I've published a free video lesson at decplay.com/FREE showing the unique DecPlay method (as featured on BBC) - to help adults / seniors learn songs on piano quickly and easily - without reading music notation.
Last week I noticed a serious key-malfunction in my Yamaha PSR-S670 keyboard, where one E-Minor-key would automatically play the above A-key in full volume and when pressing the E-Minor-key while holding down the A-key at the same time, this A-key wouldn't give off any sound. After watching your video I had the necessary confidence and insight into the keyboard interiors (which are similar for my keyboard as well, although it's a different model) to venture into opening the instrument and cleaning everything like you did, including the contact spray treatment. And before cleaning, my dad made some soldering on a contact that looked a bit damaged. So, I wanted to give you my deepest thanks for this excellent video which made our home repair possible in the first place. It saved us all the trouble and money that would have gone into professional repairs or even a new purchase. Many friendly greetings from Leipzig, Germany.
I was given an old Yamaha psr-31 with dead keys f and b. It was a different lay out opening it up to clean than this demonstration, but I followed the intentions in the video, all the while berating myself for spending so much time bent over this old thing and not understanding how dust could make these keys not work for multiple octaves. I thought after all that work it had to have been another problem that I couldn't do anything about. But lo and behold, I screwed everything back together and the damn thing works now!!!! Thank you!!!
Hi Julie, thats great to hear - so glad the video was of use. I'm thinking of doing an shorter version of the video - do you think its a bit too long? thanks Declan
Thank you very much for this video. You saved me a bundle by not having to buy a new keyboard. I had a moment of panic when I opened up my Yamaha P105 to discover the keyboard is attached very differently than yours. But the principles are the same and after a few hours of swearing, aligning and realigning screws I got it cleaned and reassembled. AND I am now happy that my Eb and A keys work again perfectly. Cheers and thanks again. PS using an electric drill/driver with an extended bit-and set at the lowest torque!-saved a lot of time.
I have the same issue right now. My Ebs and As are working in light touches but in full volume but not working in heavy touches.. do cleaning it solves the problem? Thank you.
I just purchased a P-105 that arrived with a bunch of non-working keys. Can you describe what was different from the above video when you fixed yours? Thanks!
@@In_Set it’s been a long while since I took it apart and I curse myself for taking only one photo. But if memory serves when I unscrewed the base and removed it the keys were attached in a different fashion. But if you stare at it long enough it makes sense and I just followed the tutorial. The one caveat I have is this: don’t scrape out the white goop inside the cavity-it’s piano key lubricant! My problem was simply years of dust and a bit of dog hair that had infiltrated the uncovered keyboard. I now cover the keyboard whenever I’m not playing. Sorry to be vague, but that’s the best I can remember.
Nice sharing, well described how to fix dead keyboard keys. However the cleaning of rubber pads should also be discussed as the keys won't function if the carbons inside rubber pad are rusty. I had this problem in keyboard. I simply washed the pads with water, dried and put them back on the keyboard and my keyboard is now functioning well.
Asif You are a life saver.. i had mine which was giving me such problems, washed the rubber pads with soap and water and right now its working perfectly welll
At 12:09 to your viewers. He said "Contact Cleaner" and then mentioned the WD-40 brand but he did not give you a good closeup of the can. DO NOT USE actual WD-40 (it will leave a non-conductive non-water soluable film on the contacts), you MUST use contact cleaner as he said. I just wanted to be sure your viewers picked up on that.
2 adjacent notes "dead" Cleaned as per video first time in 17/18 yrs, lots of dust and dirt removed. Weak note returned on 2 keys, then noted distortion of printed circuit board at the related section, loosened nearby screw 2 turns and slipped a short strip of zip tie under board at low point. Working perfectly, fine for another couple of decades...maybe! To be played at choir rehearsal on Saturday, first outing for a v long time! Thanks for sharing the video.
Hi, thanks for this video, I'm not a musician, but my non-technical neighbour asked me to take a look at their keyboard as several keys had stopped working. All sorted now thanks to this video. One point of interest was that there was a pattern to which keys had failed. All were in the upper 4 octaves. There were 3 black (sharp) keys, each being the A#, and 4 white keys each being an E. I wondered whether there was some reason why it should be these particular keys, based upon the functionality of the instrument?
WONDERFULLY HELPFUL!! I planned to order a new keyboard when b's and f"s in all octaves stopped working. I followed your directions and now the keyboard is restored. Thank you. BTW: I substituted a microfiber cloth that came with my new glasses when I couldn't find the gloves your recommended.
I've just watched this today, as I have the problem of some keys not working. There is no quick solution. You have to undo fifty or more screws. I missed a few, so was getting frustrated, but it was my fault. I eventually managed to get it apart, and found the piano was full of cat hairs, as expected, as the cats love to sleep on it. I am following this to the letter, as far as I can see. Will have to do all the cleaning inside, with the WD40 and the cloths, but that is better than paying £100 plus to have it repaired. This is a bit premature, as I haven't got it working yet, but it seems like the best information I have found on the Internet, so I will give the guy a thums up for this.
Was tuff getting in (models are quite different) but followed cleaning instructions and it's MIRACULOUS...feels like a whole new piano. MUCHAS GRACIAS!!
The A and D# keys on my Yamaha DGX 203 suddenly stopped working. Found this video and had it working in less than 1 1/2 hours! Thanks a bunch for the video.
Thank You for this! I took my wife's Yamaha Keyboard apart and did the process, different model but close enough. Worked well. She said the notes sound more clear now.
Thanks a lot, dude! I was scared when a certain key on my keyboard started behaving abnormally...the key sometimes was unresponsive and sometimes would produce a loud sound unexpectedly... I thought it might be some circuit board problem and I might have to replace it...which could've cost me a lot of time and money...but tried the same method in the video and now my keyboard is as good as a new one!
I had a few keys that stopped working. I used a hair dryer to blow dust out through keys, and all vents. No need to open the piano or unscrew anything. Works fine now! 😂
Thanks for this comment. None of my c or f# keys were working on my Yamaha keyboard. A hairdryer on cold setting fixed all my issues in less than 5 minutes! Saved me hundreds of dollars!!!
i watched this video and cleaned my used Elegance JC-6188 keyboard that i just purchased on marketplace. It was making noise and had a dead "G" key and was kind of loud when i played, but even though you have a different brand -- your video helped --it works now!! Kudos to you. Thanks
Thank you DecPlay!! Your video helped me fix my son's Yamaha keyboard, which was playing all sorts of extra notes when 3 or more keys were played at the same time. Your method worked and it was fun to take the piano apart and put it back together. Grateful for your guidance!! Blessings.
BRAVISSIMO! I had an F# key that would not sound, or would sound only at full volume, I followed this video and VOILA, FIXED! I dare say that once cleaned properly ALL the keys sounded better, this maybe a routine maintenance if you have pets or you rehearsal space is prone to dust and dander. Thank you!
Very good video and well-explained. I was a bit wary, but now I have full confidence that I can repair the loud key on my P125! Thanks again for taking the time to share your experience with others.
I just bought the P125 last month. For some reason, It doesn't quite sound as loud as the one did at the store and I am so confused as to way. Something told me to open it up at the store to try and make sure mines had the same settings as the one I was playing that convinced me of buying this one. the highest key has such a faint sound, I have maxed out the volume on all fronts as much as possible. I feel like I may have been sold a manufacturers dud from guitar center. Do you have any advice?
Thanks for this! My problem was C2 and B3 working intermittently on my Yamaha Psr ew310. So I blew out all the dust and cleaned the connectors as instructed which restored the B but no joy with the C no matter what I tried. In the end out of desperation, I literally swapped out the entire key set and pad with the next one along. Don’t ask me how, but it worked!
Wow! Problem solved! 💯 My keyboard is a Yamaha PSR-E373 and it had this problem where the D and G# keys on each octave either played in full touch response volume or had no sound at all. We were supposed to have it sent to repair, but I tried to look up for a solution online first. I saw this, followed the steps, and cleaned the heck out of it (it was filled with webs and small spiders 😅), and finally reassembled it and tested it.. and it works! Thanks so much! It sure saved us some extra money! 😁
I’m not sure - as they contain an electrical contact, I personally wouldn’t use water on them - compressed air might be better or Circuit board cleaner
Nice video. At 15:31 Also clean the Carbon Impregnated Rubber contacts inside those gray rubber overlays. Pollution in the air causes a thin glaze on them over time. You may have to lightly roughen up the surface with 200 grit sandpaper (that is 200 grains per inch in US sandpaper, I am not sure how sandpaper is designated in other parts of the world), and then clean again. If you find a rubber contact that is deformed, cracked, and simply not like the rest, you can replace the Grey Overlay or replace the Carbon Rubber contact with one from an old remote control and the like. Never throw away an old remote. Those carbon/rubber contacts are hard to find as nobody knows exactly what they are called.
Super helpful video! Thank you so much for explaining everything in such great detail! A few of the keys on my keyboard were dead, especially all the C keys. My keyboard is around 17 years old (unused for most of those years) and had never been cleaned inside before. Had to wash the rubber pads to get the dust off completely, but after drying them up completely and using the contact cleaner on the board, the keyboard is working flawlessly and feels brand new!! Thank you!! ❤
I used your video to help me fix a key on my Roland e-28. Different construction but I figured it out. Very tedious as I had to l lift out every single key separately. But it's now fixed and I'm happy 😊 Thanks
Got it sorted thanks, 2 things I did was wipe the contact strip with 93% alcohol and tried to push the connections in. I don’t know which one worked but it’s playing ok now.
I was about to sens a 'donated' 88 note digital yamaha to the dump I will do this and rescue and pass on to someone who cannot afford one for their very talents daughter. . Your video has many ripple effects. Thank you and God bless you. .
Thank u for actually showing every step. For us that think about attempting something for the 1st time it helps.The Yamaha YPG 235 had screws hidden where the batteries go. Couldn’t figure why cover wouldn’t open lol .. thank you for ur help
Here's a tip from Katrina Zawawi - @DecPlayPiano Hi Dec, thanks for keeping in touch. Given that it seemed, bizarrely, to only be working properly from about 2.35pm onwards, it occurred to me that, as we live in a small bedsit with winter washing, cooking and a high degree of humidity, it might just be condensation (although why this has only started to be a problem now I'm not sure, we've been here over a year and it was just as damp last year). Anyway, this morning my boyfriend got out a hairdryer and applied it up and down the keys, particularly the hinge-ends over where the circuits are, and after 3 minutes or so switched the keyboard on again and... hey presto, it was fine! So if anyone is having probs that can't be solved by an interior clean, it's maybe worth asking what conditions they live in, and just try running a hairdryer over the key-tops for about 3 minutes. NB we had already tried leaving the dust cover on all night, but that made no difference. Hope this might be of use.
I am truly getting annoyed and angry with my P-45. Cleaning everything the first few times was kinda fun. One enjoys being able to repair stuff themselves. And I was very thorough with my work. I put the rubber elements in lukewarm water and soap, the carefully dried them. I also wiped the surfaces on the circuit board not just with wet cloth but with a cloth dipped in hydrogen peroxide just in case the problem had been caused by some form of fungi. The keyboard worked like new for a few months after that, then a key which I had no problems with before, started acting up - maximum loudness, then silence and so on. I believe the technology used is just not right. Anyway unwilling to unscrew the 50 plus screws I looked for solutions in Internet again and noticed your post. After blowing the hairdryer at the silent key, the key woke up - well sort of. That suggests that you might be on to something. Still I am hoping to eventually stumble upon a more permanent solution. Thanks and regards
Thanks man. You helped me a lot. I had to search for other videos too, because my keyboard is a Yamaha PSR 550. The steps to open it changed a bit. I also made a dry cleaning only, with cotton swabs. But, your video put me on the right track. Best regards.
Excellent tutorial. I have an older keyboard that's been in storage for a few years, and several keys arent working. I was thinking about buying a new one, but this video makes it look fairly easy to fix it, so I'll at least give it a try.
I have a Yamaha P115B with the same issue (on D and Ab on the last 2 octaves). The disassembly does not match your video, since to reach the keys you have to disassemble another layer but the solution works nevertheless. Just cleaning the contacts and the rubber did the trick! Thanks!
Hey Buddy.. I have the same problem.. P115B and last two octaves D and Ab !!!! But a bit worried if i would mess it up after disassembling.. :( how did you really clean the contact did you use any contact cleaner spray like indicated in this video ?
@@sujithkv82 Hey man. I won't lie to you, I was afraid more than one time of breaking something while doing the repair myself, so I won't blind say for you to just do it. It's not hard, but it's not a walk in the park if you never done it before, specially since its harder than the model in this video. I found the P115B service manual first at elektrotanya.com/yamaha_p-115b_p-115wh_p-45b.pdf/download.html#dl, this was essential. I followed its instructions, looking at the video in the similar parts just to make sure it was similar enough but there are a lot of differences. First, its easier to leave the keyboard upside down and lift it when removing the lower cover, differently from the video, because the keys wont be exposed yet (see the picture in the manual). Take the same care in lifting the proper side to avoid detaching or breaking the flat cables which connect the 2 sides. Then you have an extra step compared to the video, more screws to access the keys (section A-6 from the manual). Then you can lift it up. It has an specific angle for it to move out (careful, its heavy), and then you can place it carefully on the lower assembly (the other part you removed before). Now you will be in a similar state as the video and can do more or less the same steps from there. Yes, I used a contact cleaner just like in the video, cleaned up with a soft cloth (a lot of dust came out of the contacts) and just on the side with problems (last 2 octaves and the last C, which needs to be removed before its possible to remove the rest). I let it dry for a couple of minutes before reassembling. When reassembling, make sure the keyboard is snugly fit on the position, otherwise only when doing the last step you will see the case wont close. You will know something is not right if the bars below the keys become stuck for any reason. Lift it up and reposition again. I am talking by memory here, so don't blindly trust me, there is a risk of breaking your equipment so make sure you are accepting this before trying. Otherwise, breathe, take it slow and good luck!
@DecPlayPiano, @Ricardo Trindade, thanks a bunch .. At least for now, it did work for me too.. :) I am still wondering how come it affected only for D and Ab for multiple octaves!!! that too for me and @Ricardo.. The contact not clean should typically affect all keys the same way... So, I am a bit worried if some more issues are hidden.. Will observe for couple of months and update.. Thanks again.
For some time now, when I touch the body (except for the wooden part) or when I hit the keys a little hard, my piano makes a sound like a marble. This issue gets worse when I hold the pedal and play music.(I tried even when the piano is turned off and there is no electric current in it, it still makes this sound). What is the problem? My piano model is clp725
THANK YOU SO MUCH! It was GREAT help for my P-45 piano Yamaha.Your videos are very clear and helpful.It is very nice that you think of helping other people!🙂🙂🙂
You are very welcome - I learn a lot from videos other people have posted, so it is a pleasure to return the favour :) P45's are great - hope it is giving you lots of fun!
Thank you!!! My gig bag has been disintegrating and leaving little nylon fibers everywhere. Shortly after throwing it away, I developed a problem with my A and Eb. Since they're a tritone pair and the problem went beyond one octave, I thought it might be corrupted firmware or a failing sound card. But I also suspected dust. I'm seeing that my cleaning didn't go deeply enough (I didn't remove the keys). I'm going in for the rest. And given all the nylon fibers my old bag was shedding, I suspect there's even more to clean.
I hope my Yamaha DJX is set up the same way inside. My "Main Voice" key is stuck and it hampers functions. I use this Yamaha to record a lot. Contrary to it's "toy-ish" look, this keyboard is a monster in functionality. I plan on buying another before you can't even find one. I will repost after the cleaning attempt. Usually when I take things apart they go back together in worse shape or incomplete with missing parts. Great video and love the British accent. (If you're not from Britain please don't be offended.) :). Thanks for posting.
Can confirm this fixed me dead keys of Mi, and Si (bemol) [all of them, on the entire keyboard] on Yamaha psr 295. As in the video all I did was open, disAssembl all keys - clean, and reAssembe. must note that one DO started being in full volume after reassemble it back...probably I'll need to open and reset the rubber there correctly. Thanks!
Amazing video!!! Thanks for sharing. I have a Yamaha PSR 550. And my floppy disk is stuck, rubber buttons don't respond, and sound get this disturbed line distortion thing, Any idea how to fix those? Everything seems intact to begin with.
And then they say they don´t know what to do during pandemic lockdown....For DecPlayPiano...it takes 26 minutes... for us A full hour ¡loved this tutorial! Thanks for sharing it. 💋👍
Thank you so much for posting such an informative video. Unfortunately, after following this advice to the letter and reassembling the keyboard, it appears to be no better off (although we tested like recommended just after putting the keys back on) and it seemed to work fine then. Overnight it seems to have gone back to where it was. The same keys not working. Any suggestions? Thank you for your time
one idea would be to test the keys at various stages, to try to identify at what point they go off - eg were they working after you fully assembled the keyboard or did they cease working when you put the screws in. It could be screwing the case on is causing some movement on wires or circuitboards that might have a damaged connector - so if the problem isn't dirt under the contacts, doing this might help to find the problem. Another thing to make sure the rubber contact pads are clean inside and to move the rubber pads around so they sit on different keys and see if this changes which keys have a problem.
@@DecPlayPiano Hi, thank you for the extra information. Unfortunately, we have tried your recommendations over and over, and it appears that all the C# and all the G's are prone to not sounding/full volume. This happens with the case closed or opened. Any further thoughts?
@@DecPlayPiano Thank you so much for your help. Both my partner and I are much more aware about the nature of taking a keyboard apart and putting it back together. We can do that really well, lol. But yes, I think it might need the help of a keyboard technician. We're going to speak to someone soon. Thank you again. Your video has been very helpful, even though our case is different.
@@KundaliniWithKatrina thanks for your feedback. Let me know how you get on and if you find the solution so I can share this to help others. Good luck. regards Declan
Just wonderful, I've been looking for "how do i change from octave to ableton keyboard?" for a while now, and I think this has helped. Ever heard of - Penaycer Rudimentary Preponderance - (just google it ) ? It is a good exclusive product for discovering how to play the piano easily without the headache. Ive heard some amazing things about it and my neighbour got excellent results with it.
Hi again, I’ve followed your instructions which made it very easy to do but it hasn’t solved the problem. All of my C and F# keys have no sound, any ideas ???
Hey hey hey hey. Jus sharing how I fixed this problem. All of my C and F# Keys have no sound in my Yamaha P115. What I did, I used a blower that strong enough (Literally strong air) and I pressed each keys for seconds to dry it, because the cold temp is the problem. When I turned the power on again, it's working again. 😍😍😍😍😍 I got this idea from the comment section in other video. But this vid would help as well if your keyboard have dusts inside. I hope it will solve your problem.
Thanks for sharing your solutions. I try to vacuum first to see if that fixes it but blowing air can also this lodge any dust and debris that is affecting the contacts. The only risk with blowing air is that he could move the dust and debris on to other contacts, causing a problem somewhere else, but if all else fails, then this is worth trying.
Actually I didn’t fix it to start with, i took it apart four times and had a few more problems. Eventually I was giving up, I was still trying to use the keyboard to keek up a bit of practice and the suddenly it fixed itself. I have no Idea what the problem was but perseverance seems to help
At 13:02 it is best to wipe with a linen lint free cloth. Cotton, gloves or otherwise, can leave traces of cotton fibers behind and that is not desirable. Also, when wiping, just don't slide the cloth along - that just smears the debries around. Use the "rolling wipe" technique. That is where you roll the wipe up (away) and ahead as you wipe so fresh clean cloth is always making contact as you wipe the whole length. This is the best method to clean these carbon trace overlays.
Hi! I have a yamaha clp860 and an octave of keys has just jammed. technician came and said the plastic part that holds all the keys is broken and it would necessitate a keyboard replacement costing about $1000 ! :( ...have you ever faced such an issue- any thoughts / ideas welcome! THX
Hi Konica - I'm not familiar with the clp860 keyboard - but I would recommend trying to find a replacement part before changing the entire keyboard. You could try contacting Yamaha or try ebay. Another idea would be to see if the broken plastic part could be repaired. Good luck :)
Hi! First of all, thanks for the video. I have an issue with my P125 Yamaha and I would like to know if anyone know how to fix it: When I hold any C key and after that press the imediate previous B key, that B doesnt sound at all. Simultaneously or separatly they sound like a charm, but as described they dont. Thanks for any assistance!
I have a casio keyboard and I've tried a few fixes but it seems to not be the contact itself or the silicon pad. The keys are only loud when playing multiple keys alongside them, such as chords. This is really annoying and I was hoping you would have the answer! Thank you!
Good to know that there is a possible fix for this. I haven’t had this problem yet, but in case I do I know that there is a possible solution. Thanks for the upload. I’ve got the MP 32.
Thank you for this tutorial. I clean my piaggero, and it was fine for few days. Than it stoped play those two notes per octave. I think that I clened circuit well, but my rubber strips were a bit dusty. Could you advice how to clean rubber strips? Can I wash them with dish cleaner in warm water? Thanks
the most important part of the rubber, is the metal contacts beneath the rubber - I've never washed mine and I would be cautious about damaging the metal contacts. My advice would be to vacum clean the dust off the rubber (both sides) and then using a small bit of contact cleaner on the contacts - making sure not to touch them with anything that might leave any debris behind (eg don't use tissue paper or cloth that leaves lint behind).
@@DecPlayPiano thanks for fast reply. Thats what I thought So. As its rubber it is a bit sticky.. I was not able to get rid of dust of it. But as it seems that once problem occures middle octave cuts off notes on higher octaves.. I swiched highest full octave rubber with middle. It seems to working. for now.. Thanks again.
I just saw a video that said instead of using contact cleaner, use just water or rub a no. 2 pencil on the contact points, to deposit graphite on them (and presumably improve the electrical connection)
I have a problem with a single C key: it plays fine several repeat notes, then the volume jumps up, and then it is silent for a few presses - and again. I found that on the rubber contact part, the conductive paint wore off (and the contact board was dirty from it). I plan on experimenting with salvaging some contact material from older digital stuff (rubber computer keboards? remote controls?), havent tried yet. I am not sure if resistance of the material matters (for yamaha key control board). Graphite could work too - but it will also stick onto the borad, I doubt it would last long.
I opened my keyboard cleaned it and all but my issue is still there. my all A & D# keys are not working, they work sometimes but then they stop working suddenly. I tried to press the rubber bands without my keys and those notes seemed to be working fine. I think the issue could be with all of the keys or rubber bands idk . Can you share any insights?
@@DecPlayPiano I would like to add that it used to work fine. I started learning again after not using piano for 3-4 months and encountered this issue. Just wanted to add this so maybe it would give you a better idea of the situation and you can help diagnose it. Anyways, thank you for the video and help.
Hi - all I can suggest is that you follow the steps in the video and see if that fixes the problem - if not, then it might need a keyboard repair technician to look at it.
yes - they are great keyboards for portability - but I now have 4 that have dead keys - I wonder if it's a fault with the wiring / circuit board - if anyone from Yamaha is reading - can you let us know how to do a more permanent fix than cleaning the contacts? ??
@DecPlayPiano That sucks, sorry to hear about dead keys. Wonder if the contact cleaner ? I know it is not supposed to and I have used it many times but you never know. Thanks again
@@DecPlayPiano Hi, I have a great solution! Never buy another Yama DP. I learned my lesson and went to Kawai DPs. I am about to go thru the cleaning procedure again for my 3 Yama keyboards so I can put them on Ebay and get them the hell out of here. Btw, love the action of the Kawai's medium $ kawai es920 etc. has a good action. But their GREAT Hybrid actions start at the level of the Ca49 GFC (Grand Feel Compact Hybrid Action) and up . I just bought 2 of those for my 2 different homes because of the action that (finally) feels a DP that really does feel like an acoustic. Anyway, the dead key problems seem to be less prevalent Kawai's than the epidemic ones in the Yamas. For instance my Kawai ES8 went about 5 years without any dead keys vs an average of 2-3 years for the Yamas'.
so we're not doing the crappy pecil trick to fix the keys, and just cleaning them with some deoxit? nice. do you suggest the same for the underside of the rubber bits as well?
There was no mention of him doing that. But a very mild sugar soap in warm water and soft toothbrush would suffice. If the rubber pads themselves ever give problems and cleaning doesn't work, O have use a bit of brake cleaner on a cotton bud to rub the rubber contact pads with on old remotes which got the pads working again. Just like a remote control the rubber pads can wear out, but with a very sharp blade the old ones can be carfully sliced off without cutting too deep and with flexible glue new pads applied.
Hello, I'm from Brazil I tried this on my Yamaha P95, but I forgot the order of the keybed. There are some numbers write on the top of the pieces. Do you know if I had put them in wrong position it will work as normal? (I hope write right,I speak Portuguese). Thanks for answering
I think they should work ok as long as they fit correctly - the end ones are usually different sizes - I recommend placing them in ascending order and test if they are working ok before you reassemble the case.
I live by the ocean and a couple of keys are dead. I suspect salt is on the contacts. In addition to the information on your video, is there anything else I should do to clean them? Thanks
@@DecPlayPiano Thanks for the quick response. I will try the graphite route first. As I am in a rural area of South America, getting a contact pad section will be difficult. Any other suggestions would be appreciated.
@@donwilson974 hi don - blowing compressed air on them, cleaning them with contact cleaner (using a lint free pad) and rubbing graphite from a pencil on the contacts inside the rubber, is all I can suggest. Good luck!
I will let you know how it goes... thanks for getting back to me. Should I try a light rub with fine sandpaper to get the salt off the contact (or corrosion)?
same problem with my psr e353, all keys are working in single tap, but everytime ive pressed 3 keys, only 2 keys works, and 1 key muted.. ive alredy tried to clean the rubber and the pcb also same problem.. yes your right its on key of d.. maybe the problem is on the circuit board.
@@refinetricks2712 I only know about cleaning the dust and dirt from the key contacts - your problem sounds like something else - sorry I don't know how to fix your problem.
Hi good night, nice sharing, please can you give a recomendation I´ve a Yamaha Digital Piano P-95B only the last Octave not sound, almost all keys works, the last octave have only 6 keys with not sound, please can you recomend me another thing to do. I cleaned all the electronic board and check the continuity in all buses. Or can you please share the schematic diagram. Thanks god bless you.
General question, I bought a Yamaha P35B , the headphone jack doesn't work. Any thoughts on that? Where can a new jack be purchased, and do you recommend replacing it myself. I requires soldering .
I have a yamaha portatone electronic keyboard psr 273 and i dont see a tab on the keys to pull them out so i can't clean them.. how do i solve this problem?
Some more tips. So on my keyboard, 3 keys went dead. Cleaning the landing pads and swapping the rubber membrane did not cure the problem. Looking at the circuit board, I noted that keys are wired in groups. Although the three keys were not next to each other, they were in fact part of a group. So I traced the fault to a break in the PCB track. I fixed this with a bit of soldering and the dead keys are now alive! However, all three now play louder than any others. This cannot be due to their membranes, as it is not common to all three keys. So I have more work to do!
@@DecPlayPiano like the actual keys, the white and black pieces that you push with your fingers? That's the only thing I haven't done. I'm about to try it again.
Hi I have an issue with my npv80. When I turn on the power, everything works but after playing some time, suddenly the left sound (left speaker or left output with the jack to amplifier) is gone. After repowering the keyboard it works again but after a while it simply quites again the "left sided", sound. I have already did a factory reset but that didn't resolved it. Do you have any idea what can be the cause? The keyboard is about 6 to 7 years old and I am doubting to buy another one. Is it still worthy to repair it. I hope you can give me some advice. Warm regards, Leo Luiten, Almere, The Netherlands
Hi Leo - sorry I don't know what that might be - if the wires to the speaker are not loose then I would recommend taking it to a keyboard repair technician
Did your rubber bands also show two central feet of different size, like mine? Just performed your actions on my Yamaha p-115 to fix dead keys, all of the keys are dead. I inserted my rubber pieces such that the large foot is south and the small one north. Maybe that was the wrong way. Please tell me if you remember!
@@DecPlayPiano I dont mean those. In the center they have two larger notches that press on the contacts when the key is depressed. Do you know what I mean?
@@DecPlayPiano I think 15:35 is the only time, since there we see rubber bands upside-down. Anyway, the distance to the camera is too large to make out details at this point. Though you previously referred to these notches on the underside as "contacts" and advised us to make sure no dust collects at these points. Anyway, heres an update: I went through the whole thing again, and actually replaced the rubber bands such that now the longer notch has contact to the upper contact and vice versa. Plugged the power in, and all keys sound again! In hindsight this makes sense, as the contact boards need some way of measuring velocity. I guess in order to do that it measures the distance between the lower and upper contacts being struck. Thats why the notches need different lenghts, so that the upper contact is struck at a delay. I guess in my case having inserted the rubber bands in wrong orientation avoided striking the upper contact, and thus without the upper contact registering anything the velocity converges to zero and there is no sound. Anyway, thanks to your video I have no dead keys anymore! Thanks a lot!
The middle part of the rubber does have a large foot that is near the top. They are near the part that has the rubber portrusions that get inserted into the mother board. You can't put the rubber part backwards because the rubber portrusion wouldn't have anywhere to be inserted.
DecPlayPiano It’s a DJ X Yamaha and it seems like the only notes that work are the 7 lower keys the rest play notes that are the wrong tune and they will randomly be loud quiet loud quiet I was hoping to fix it since I ordered it online for $150 I could still return it probably but the shipping alone is $100 so I’m hoping I can get it fixed for reasonable price do you know where I could Find out what the problem is?
DecPlayPiano I don’t expect you to reply but thank you for sharing your video because that’s very informative and it was a very well-made video, It would’ve been nice to see up close for a little bit but then again I have a little phone screen out loud thanks for replying
Can you please tell me that all of my keyboards A keys in every octave are not giving sound when i press them but the key gives sound a little later . Can you please tell me what to do
I Don't think so as my video is designed to show how to remove dust and dirt which stop the keys working properly. Water damage is a different problem. I definitely wouldn't turn on the keyboard until it has totally dried out. If the water evaporates without causing damage then you might be ok - if not, then I would recommend taking it to a keyboard repair technician.
I cleaned the contacts as directed. The problem remains. It is the upper 3 F#'s and the upper 2 C notes. Since it is essentially the same (2) notes but in sequence, it might be something else. Any suggestions? Thanks.
Don Wilson have you vacuumed out the circuit board and checked that there is no dust or debris that might be causing a problem? If so, then you could try replacing the rubber contact pads.
If you put the rubber pads in upside down, the keys will be loud automatically (at least on my Kurzweil). I doubt that is the problem given the spread-out nature of those keys, but thought I'd mention it.
Hi Jonece - if there is no sound at all and the volume is up and there isn't anything plugged in the headphone socket, then it sounds like a problem that would need a keyboard technician to fix.

I've published a free video lesson at decplay.com/FREE showing the unique DecPlay method (as featured on BBC) - to help adults / seniors learn songs on piano quickly and easily - without reading music notation.
Last week I noticed a serious key-malfunction in my Yamaha PSR-S670 keyboard, where one E-Minor-key would automatically play the above A-key in full volume and when pressing the E-Minor-key while holding down the A-key at the same time, this A-key wouldn't give off any sound. After watching your video I had the necessary confidence and insight into the keyboard interiors (which are similar for my keyboard as well, although it's a different model) to venture into opening the instrument and cleaning everything like you did, including the contact spray treatment. And before cleaning, my dad made some soldering on a contact that looked a bit damaged. So, I wanted to give you my deepest thanks for this excellent video which made our home repair possible in the first place. It saved us all the trouble and money that would have gone into professional repairs or even a new purchase. Many friendly greetings from Leipzig, Germany.
I was given an old Yamaha psr-31 with dead keys f and b. It was a different lay out opening it up to clean than this demonstration, but I followed the intentions in the video, all the while berating myself for spending so much time bent over this old thing and not understanding how dust could make these keys not work for multiple octaves. I thought after all that work it had to have been another problem that I couldn't do anything about. But lo and behold, I screwed everything back together and the damn thing works now!!!! Thank you!!!
Hi Julie, thats great to hear - so glad the video was of use. I'm thinking of doing an shorter version of the video - do you think its a bit too long? thanks Declan
It's just right. Don't change a thing. Thanks!
Thank you very much for this video. You saved me a bundle by not having to buy a new keyboard. I had a moment of panic when I opened up my Yamaha P105 to discover the keyboard is attached very differently than yours. But the principles are the same and after a few hours of swearing, aligning and realigning screws I got it cleaned and reassembled. AND I am now happy that my Eb and A keys work again perfectly. Cheers and thanks again. PS using an electric drill/driver with an extended bit-and set at the lowest torque!-saved a lot of time.
I have the same issue right now. My Ebs and As are working in light touches but in full volume but not working in heavy touches.. do cleaning it solves the problem? Thank you.
I just purchased a P-105 that arrived with a bunch of non-working keys. Can you describe what was different from the above video when you fixed yours? Thanks!
@@ruizguevarra2482 sorry for delay. I just saw this. The answer is yes. Keyboard still working perfectly!
@@In_Set it’s been a long while since I took it apart and I curse myself for taking only one photo. But if memory serves when I unscrewed the base and removed it the keys were attached in a different fashion. But if you stare at it long enough it makes sense and I just followed the tutorial. The one caveat I have is this: don’t scrape out the white goop inside the cavity-it’s piano key lubricant! My problem was simply years of dust and a bit of dog hair that had infiltrated the uncovered keyboard. I now cover the keyboard whenever I’m not playing. Sorry to be vague, but that’s the best I can remember.
@@GaryBoire Thanks very much! Appreciate it :)
Nice sharing, well described how to fix dead keyboard keys. However the cleaning of rubber pads should also be discussed as the keys won't function if the carbons inside rubber pad are rusty. I had this problem in keyboard. I simply washed the pads with water, dried and put them back on the keyboard and my keyboard is now functioning well.
Hi Asif - thanks for sharing
Thanks, I wondered if those pads might need some extra treatment.
Great tip! I've had problematic keys on my Behringer UMX61 for awhile. Hope to review it fully tonight.
@@xversacex I will pray for your success.
Asif You are a life saver.. i had mine which was giving me such problems, washed the rubber pads with soap and water and right now its working perfectly welll
At 12:09 to your viewers. He said "Contact Cleaner" and then mentioned the WD-40 brand but he did not give you a good closeup of the can. DO NOT USE actual WD-40 (it will leave a non-conductive non-water soluable film on the contacts), you MUST use contact cleaner as he said. I just wanted to be sure your viewers picked up on that.
2 adjacent notes "dead"
Cleaned as per video first time in 17/18 yrs, lots of dust and dirt removed.
Weak note returned on 2 keys, then noted distortion of printed circuit board at the related section, loosened nearby screw 2 turns and slipped a short strip of zip tie under board at low point. Working perfectly, fine for another couple of decades...maybe! To be played at choir rehearsal on Saturday, first outing for a v long time! Thanks for sharing the video.
fab :)
Hi, thanks for this video, I'm not a musician, but my non-technical neighbour asked me to take a look at their keyboard as several keys had stopped working. All sorted now thanks to this video. One point of interest was that there was a pattern to which keys had failed. All were in the upper 4 octaves. There were 3 black (sharp) keys, each being the A#, and 4 white keys each being an E. I wondered whether there was some reason why it should be these particular keys, based upon the functionality of the instrument?
WONDERFULLY HELPFUL!!
I planned to order a new keyboard when b's and f"s in all octaves stopped working. I followed your directions and now the keyboard is restored. Thank you. BTW: I substituted a microfiber cloth that came with my new glasses when I couldn't find the gloves your recommended.
I've just watched this today, as I have the problem of some keys not working.
There is no quick solution. You have to undo fifty or more screws. I missed a few, so was getting frustrated, but it was my fault.
I eventually managed to get it apart, and found the piano was full of cat hairs, as expected, as the cats love to sleep on it.
I am following this to the letter, as far as I can see.
Will have to do all the cleaning inside, with the WD40 and the cloths, but that is better than paying £100 plus to have it repaired.
This is a bit premature, as I haven't got it working yet, but it seems like the best information I have found on the Internet, so I will give the guy a thums up for this.
Thanks - yea the screws are a pain!
Didya fix it?
I just fixed my yamaha with the help of your video...thanks a lot....you saved me a lot of money😀😀😀😀😀😀😀
Was tuff getting in (models are quite different) but followed cleaning instructions and it's MIRACULOUS...feels like a whole new piano. MUCHAS GRACIAS!!
so glad you found it useful :)
The A and D# keys on my Yamaha DGX 203 suddenly stopped working. Found this video and had it working in less than 1 1/2 hours! Thanks a bunch for the video.
hi Dan glad it worked for you - thanks for the feedback
Thank You for this! I took my wife's Yamaha Keyboard apart and did the process, different model but close enough. Worked well. She said the notes sound more clear now.
great - glad it helped :)
Thanks a lot, dude! I was scared when a certain key on my keyboard started behaving abnormally...the key sometimes was unresponsive and sometimes would produce a loud sound unexpectedly... I thought it might be some circuit board problem and I might have to replace it...which could've cost me a lot of time and money...but tried the same method in the video and now my keyboard is as good as a new one!
thanks for your feedback - so glad it helped :)
did you use a contact cleaner? or you just cleaned it normally?
I had a few keys that stopped working. I used a hair dryer to blow dust out through keys, and all vents. No need to open the piano or unscrew anything. Works fine now! 😂
great feedback thanks
Thanks for this comment. None of my c or f# keys were working on my Yamaha keyboard. A hairdryer on cold setting fixed all my issues in less than 5 minutes! Saved me hundreds of dollars!!!
i watched this video and cleaned my used Elegance JC-6188 keyboard that i just purchased on marketplace. It was making noise and had a dead "G" key and was kind of loud when i played, but even though you have a different brand -- your video helped --it works now!! Kudos to you. Thanks
Thank you DecPlay!! Your video helped me fix my son's Yamaha keyboard, which was playing all sorts of extra notes when 3 or more keys were played at the same time. Your method worked and it was fun to take the piano apart and put it back together. Grateful for your guidance!! Blessings.
Glad my video helped :)
BRAVISSIMO! I had an F# key that would not sound, or would sound only at full volume, I followed this video and VOILA, FIXED! I dare say that once cleaned properly ALL the keys sounded better, this maybe a routine maintenance if you have pets or you rehearsal space is prone to dust and dander. Thank you!
thanks for your feedback - so glad my video was of help to you :)
@@DecPlayPiano thank you for sharing! I have an older casio that I am goin to try and fix next!
Very good video and well-explained. I was a bit wary, but now I have full confidence that I can repair the loud key on my P125! Thanks again for taking the time to share your experience with others.
thanks for the feedback - much appreciated
I just bought the P125 last month. For some reason, It doesn't quite sound as loud as the one did at the store and I am so confused as to way. Something told me to open it up at the store to try and make sure mines had the same settings as the one I was playing that convinced me of buying this one. the highest key has such a faint sound, I have maxed out the volume on all fronts as much as possible. I feel like I may have been sold a manufacturers dud from guitar center. Do you have any advice?
@@TriggaTreDay Sorry, no I don't.
Outstanding! I had a duff Ab3 for months and now its ALIVE! Thanks so much.
Hi Craig - so glad my video helped :) regards Declan
Thanks for this! My problem was C2 and B3 working intermittently on my Yamaha Psr ew310. So I blew out all the dust and cleaned the connectors as instructed which restored the B but no joy with the C no matter what I tried. In the end out of desperation, I literally swapped out the entire key set and pad with the next one along. Don’t ask me how, but it worked!
Wow! Problem solved! 💯
My keyboard is a Yamaha PSR-E373 and it had this problem where the D and G# keys on each octave either played in full touch response volume or had no sound at all. We were supposed to have it sent to repair, but I tried to look up for a solution online first. I saw this, followed the steps, and cleaned the heck out of it (it was filled with webs and small spiders 😅), and finally reassembled it and tested it.. and it works!
Thanks so much! It sure saved us some extra money! 😁
Wow. Small spiders??? So you fixed it?
I also have a yamaha 373. Just one key is not working.
What did you do?
Hey! Please reply , Can i Simply Soke those rubbery , grey strip on the green circuit underneath the Keys With Water?10:28
I’m not sure - as they contain an electrical contact, I personally wouldn’t use water on them - compressed air might be better or Circuit board cleaner
Nice video. At 15:31 Also clean the Carbon Impregnated Rubber contacts inside those gray rubber overlays. Pollution in the air causes a thin glaze on them over time. You may have to lightly roughen up the surface with 200 grit sandpaper (that is 200 grains per inch in US sandpaper, I am not sure how sandpaper is designated in other parts of the world), and then clean again. If you find a rubber contact that is deformed, cracked, and simply not like the rest, you can replace the Grey Overlay or replace the Carbon Rubber contact with one from an old remote control and the like. Never throw away an old remote. Those carbon/rubber contacts are hard to find as nobody knows exactly what they are called.
Super helpful video! Thank you so much for explaining everything in such great detail! A few of the keys on my keyboard were dead, especially all the C keys. My keyboard is around 17 years old (unused for most of those years) and had never been cleaned inside before. Had to wash the rubber pads to get the dust off completely, but after drying them up completely and using the contact cleaner on the board, the keyboard is working flawlessly and feels brand new!! Thank you!! ❤
so glad my video was of help :)
I used your video to help me fix a key on my Roland e-28. Different construction but I figured it out. Very tedious as I had to l lift out every single key separately. But it's now fixed and I'm happy 😊 Thanks
Glad my video was useful
Got it sorted thanks, 2 things I did was wipe the contact strip with 93% alcohol and tried to push the connections in. I don’t know which one worked but it’s playing ok now.
great - glad it is sorted - thanks for sharing how you did it
Thank you for the video. Today I learned how to repair my keyboard by myself. Worked liked a charme.
glad it worked for you - thanks for sharing your feedback
I was about to sens a 'donated' 88 note digital yamaha to the dump I will do this and rescue and pass on to someone who cannot afford one for their very talents daughter. . Your video has many ripple effects. Thank you and God bless you. .
Great video. Can you please identify the contact cleaner you used and whether it is a deoxit type of cleaner. Many thanks.
It is WD-40 contact cleaner - not sure about ‘deoxit’
Thank u for actually showing every step. For us that think about attempting something for the 1st time it helps.The Yamaha YPG 235 had screws hidden where the batteries go. Couldn’t figure why cover wouldn’t open lol .. thank you for ur help
Hi Cindy - thanks for your feedback - glad the video was of help to you.
Here's a tip from Katrina Zawawi - @DecPlayPiano Hi Dec, thanks for keeping in touch. Given that it seemed, bizarrely, to only be working properly from about 2.35pm onwards, it occurred to me that, as we live in a small bedsit with winter washing, cooking and a high degree of humidity, it might just be condensation (although why this has only started to be a problem now I'm not sure, we've been here over a year and it was just as damp last year). Anyway, this morning my boyfriend got out a hairdryer and applied it up and down the keys, particularly the hinge-ends over where the circuits are, and after 3 minutes or so switched the keyboard on again and... hey presto, it was fine! So if anyone is having probs that can't be solved by an interior clean, it's maybe worth asking what conditions they live in, and just try running a hairdryer over the key-tops for about 3 minutes. NB we had already tried leaving the dust cover on all night, but that made no difference. Hope this might be of use.
I am truly getting annoyed and angry with my P-45. Cleaning everything the first few times was kinda fun. One enjoys being able to repair stuff themselves. And I was very thorough with my work. I put the rubber elements in lukewarm water and soap, the carefully dried them. I also wiped the surfaces on the circuit board not just with wet cloth but with a cloth dipped in hydrogen peroxide just in case the problem had been caused by some form of fungi. The keyboard worked like new for a few months after that, then a key which I had no problems with before, started acting up - maximum loudness, then silence and so on. I believe the technology used is just not right. Anyway unwilling to unscrew the 50 plus screws I looked for solutions in Internet again and noticed your post. After blowing the hairdryer at the silent key, the key woke up - well sort of. That suggests that you might be on to something. Still I am hoping to eventually stumble upon a more permanent solution. Thanks and regards
Great tip - thanks
Thanks man. You helped me a lot. I had to search for other videos too, because my keyboard is a Yamaha PSR 550. The steps to open it changed a bit. I also made a dry cleaning only, with cotton swabs. But, your video put me on the right track. Best regards.
the upper octive on my dgx-500 has shifted in sound down 2 notes. Can that be fixed. otherwise the keyboard plays just fine.
sorry - I don't know the answer to that
Excellent tutorial. I have an older keyboard that's been in storage for a few years, and several keys arent working. I was thinking about buying a new one, but this video makes it look fairly easy to fix it, so I'll at least give it a try.
Has it worked? I have the same situation
How’d it go?
I dislike these these comments that don’t leave closure
I have a Yamaha P115B with the same issue (on D and Ab on the last 2 octaves). The disassembly does not match your video, since to reach the keys you have to disassemble another layer but the solution works nevertheless. Just cleaning the contacts and the rubber did the trick! Thanks!
Hi Ricardo - glad to hear it :)
Hey Buddy.. I have the same problem.. P115B and last two octaves D and Ab !!!! But a bit worried if i would mess it up after disassembling.. :( how did you really clean the contact did you use any contact cleaner spray like indicated in this video ?
@@sujithkv82 Hey man. I won't lie to you, I was afraid more than one time of breaking something while doing the repair myself, so I won't blind say for you to just do it. It's not hard, but it's not a walk in the park if you never done it before, specially since its harder than the model in this video.
I found the P115B service manual first at elektrotanya.com/yamaha_p-115b_p-115wh_p-45b.pdf/download.html#dl, this was essential.
I followed its instructions, looking at the video in the similar parts just to make sure it was similar enough but there are a lot of differences. First, its easier to leave the keyboard upside down and lift it when removing the lower cover, differently from the video, because the keys wont be exposed yet (see the picture in the manual). Take the same care in lifting the proper side to avoid detaching or breaking the flat cables which connect the 2 sides.
Then you have an extra step compared to the video, more screws to access the keys (section A-6 from the manual). Then you can lift it up. It has an specific angle for it to move out (careful, its heavy), and then you can place it carefully on the lower assembly (the other part you removed before). Now you will be in a similar state as the video and can do more or less the same steps from there.
Yes, I used a contact cleaner just like in the video, cleaned up with a soft cloth (a lot of dust came out of the contacts) and just on the side with problems (last 2 octaves and the last C, which needs to be removed before its possible to remove the rest). I let it dry for a couple of minutes before reassembling.
When reassembling, make sure the keyboard is snugly fit on the position, otherwise only when doing the last step you will see the case wont close. You will know something is not right if the bars below the keys become stuck for any reason. Lift it up and reposition again.
I am talking by memory here, so don't blindly trust me, there is a risk of breaking your equipment so make sure you are accepting this before trying. Otherwise, breathe, take it slow and good luck!
@@rtrind very elaborate bro!! Thanks a lot..
@DecPlayPiano, @Ricardo Trindade, thanks a bunch .. At least for now, it did work for me too.. :) I am still wondering how come it affected only for D and Ab for multiple octaves!!! that too for me and @Ricardo.. The contact not clean should typically affect all keys the same way... So, I am a bit worried if some more issues are hidden.. Will observe for couple of months and update.. Thanks again.
For some time now, when I touch the body (except for the wooden part) or when I hit the keys a little hard, my piano makes a sound like a marble. This issue gets worse when I hold the pedal and play music.(I tried even when the piano is turned off and there is no electric current in it, it still makes this sound). What is the problem?
My piano model is clp725
THANK YOU SO MUCH! It was GREAT help for my P-45 piano Yamaha.Your videos are very clear and helpful.It is very nice that you think of helping other people!🙂🙂🙂

Thank you very much but mine changed it is not flowing the sounds 11:31
Thank you!!! My gig bag has been disintegrating and leaving little nylon fibers everywhere. Shortly after throwing it away, I developed a problem with my A and Eb. Since they're a tritone pair and the problem went beyond one octave, I thought it might be corrupted firmware or a failing sound card. But I also suspected dust. I'm seeing that my cleaning didn't go deeply enough (I didn't remove the keys). I'm going in for the rest. And given all the nylon fibers my old bag was shedding, I suspect there's even more to clean.
Worked perfectly. I had every D and A flat not working . All fixed for the cost of some contact cleaning spray
Than you

Bro this method fixed my keyboard. Hope you're doing well, thanks for the content.
Glad it worked for you 😊
I hope my Yamaha DJX is set up the same way inside. My "Main Voice" key is stuck and it hampers functions. I use this Yamaha to record a lot. Contrary to it's "toy-ish" look, this keyboard is a monster in functionality. I plan on buying another before you can't even find one. I will repost after the cleaning attempt. Usually when I take things apart they go back together in worse shape or incomplete with missing parts. Great video and love the British accent. (If you're not from Britain please don't be offended.) :). Thanks for posting.
Can confirm this fixed me dead keys of Mi, and Si (bemol) [all of them, on the entire keyboard] on Yamaha psr 295. As in the video all I did was open, disAssembl all keys - clean, and reAssembe. must note that one DO started being in full volume after reassemble it back...probably I'll need to open and reset the rubber there correctly.
Thanks!
thats great thanks for the feedback
Amazing video!!! Thanks for sharing.
I have a Yamaha PSR 550. And my floppy disk is stuck, rubber buttons don't respond, and sound get this disturbed line distortion thing,
Any idea how to fix those?
Everything seems intact to begin with.
I don't know about floppy disk or distortion issues unfortunately
@@DecPlayPiano Thanks for an answer regardless. ^^
Great video. Gonna take apart a reface CP with a missing note. I know it's a smaller scale, but I think I have the general idea. Thanks.
And then they say they don´t know what to do during pandemic lockdown....For DecPlayPiano...it takes 26 minutes... for us A full hour ¡loved this tutorial! Thanks for sharing it. 💋👍
Thank you so much for posting such an informative video. Unfortunately, after following this advice to the letter and reassembling the keyboard, it appears to be no better off (although we tested like recommended just after putting the keys back on) and it seemed to work fine then. Overnight it seems to have gone back to where it was. The same keys not working. Any suggestions? Thank you for your time
one idea would be to test the keys at various stages, to try to identify at what point they go off - eg were they working after you fully assembled the keyboard or did they cease working when you put the screws in. It could be screwing the case on is causing some movement on wires or circuitboards that might have a damaged connector - so if the problem isn't dirt under the contacts, doing this might help to find the problem. Another thing to make sure the rubber contact pads are clean inside and to move the rubber pads around so they sit on different keys and see if this changes which keys have a problem.
@@DecPlayPiano Hi, thank you for the extra information. Unfortunately, we have tried your recommendations over and over, and it appears that all the C# and all the G's are prone to not sounding/full volume. This happens with the case closed or opened. Any further thoughts?
Hi Katrina - I'm not sure what else to suggest, other than to try a keyboard technician.
@@DecPlayPiano Thank you so much for your help. Both my partner and I are much more aware about the nature of taking a keyboard apart and putting it back together. We can do that really well, lol. But yes, I think it might need the help of a keyboard technician. We're going to speak to someone soon. Thank you again. Your video has been very helpful, even though our case is different.
@@KundaliniWithKatrina thanks for your feedback. Let me know how you get on and if you find the solution so I can share this to help others. Good luck. regards Declan

glad to be of help - let me know how you get on
Just wonderful, I've been looking for "how do i change from octave to ableton keyboard?" for a while now, and I think this has helped. Ever heard of - Penaycer Rudimentary Preponderance - (just google it ) ? It is a good exclusive product for discovering how to play the piano easily without the headache. Ive heard some amazing things about it and my neighbour got excellent results with it.
Please where do i get the contact cleaner.
I buy the WD40 contact cleaner online from Amazon
Hi again, I’ve followed your instructions which made it very easy to do but it hasn’t solved the problem. All of my C and F# keys have no sound, any ideas ???
glad to hear you have now sorted this with alcohol cleaner and pushing in the connectors
Hey hey hey hey. Jus sharing how I fixed this problem. All of my C and F# Keys have no sound in my Yamaha P115. What I did, I used a blower that strong enough (Literally strong air) and I pressed each keys for seconds to dry it, because the cold temp is the problem. When I turned the power on again, it's working again. 😍😍😍😍😍 I got this idea from the comment section in other video. But this vid would help as well if your keyboard have dusts inside. I hope it will solve your problem.
Thanks for sharing your solutions. I try to vacuum first to see if that fixes it but blowing air can also this lodge any dust and debris that is affecting the contacts. The only risk with blowing air is that he could move the dust and debris on to other contacts, causing a problem somewhere else, but if all else fails, then this is worth trying.
Actually I didn’t fix it to start with, i took it apart four times and had a few more problems. Eventually I was giving up, I was still trying to use the keyboard to keek up a bit of practice and the suddenly it fixed itself. I have no Idea what the problem was but perseverance seems to help
At 13:02 it is best to wipe with a linen lint free cloth. Cotton, gloves or otherwise, can leave traces of cotton fibers behind and that is not desirable. Also, when wiping, just don't slide the cloth along - that just smears the debries around. Use the "rolling wipe" technique. That is where you roll the wipe up (away) and ahead as you wipe so fresh clean cloth is always making contact as you wipe the whole length. This is the best method to clean these carbon trace overlays.
Thank you very much for this! My daughter dropped milk into some keys of a Yamaha E463 and this helped me fix the dead keys.
glad it helped - thanks for the feedback :)
Hi! I have a yamaha clp860 and an octave of keys has just jammed. technician came and said the plastic part that holds all the keys is broken and it would necessitate a keyboard replacement costing about $1000 ! :( ...have you ever faced such an issue- any thoughts / ideas welcome! THX
Hi Konica - I'm not familiar with the clp860 keyboard - but I would recommend trying to find a replacement part before changing the entire keyboard. You could try contacting Yamaha or try ebay. Another idea would be to see if the broken plastic part could be repaired. Good luck :)
@@DecPlayPiano -Ok Thanks very much for your response. I will try that. THX
Hi! First of all, thanks for the video. I have an issue with my P125 Yamaha and I would like to know if anyone know how to fix it:
When I hold any C key and after that press the imediate previous B key, that B doesnt sound at all. Simultaneously or separatly they sound like a charm, but as described they dont. Thanks for any assistance!
I have a casio keyboard and I've tried a few fixes but it seems to not be the contact itself or the silicon pad. The keys are only loud when playing multiple keys alongside them, such as chords. This is really annoying and I was hoping you would have the answer! Thank you!
sorry - I'm not sure what that could be
Good to know that there is a possible fix for this. I haven’t had this problem yet, but in case I do I know that there is a possible solution. Thanks for the upload. I’ve got the MP 32.
thanks for the feedback - the NP32 is a great keyboard - I hope you won't need to clean under the keys for a long time :)
Thank you for this tutorial. I clean my piaggero, and it was fine for few days. Than it stoped play those two notes per octave. I think that I clened circuit well, but my rubber strips were a bit dusty. Could you advice how to clean rubber strips? Can I wash them with dish cleaner in warm water? Thanks
the most important part of the rubber, is the metal contacts beneath the rubber - I've never washed mine and I would be cautious about damaging the metal contacts. My advice would be to vacum clean the dust off the rubber (both sides) and then using a small bit of contact cleaner on the contacts - making sure not to touch them with anything that might leave any debris behind (eg don't use tissue paper or cloth that leaves lint behind).
@@DecPlayPiano thanks for fast reply. Thats what I thought So. As its rubber it is a bit sticky.. I was not able to get rid of dust of it. But as it seems that once problem occures middle octave cuts off notes on higher octaves.. I swiched highest full octave rubber with middle. It seems to working. for now.. Thanks again.
I just saw a video that said instead of using contact cleaner, use just water or rub a no. 2 pencil on the contact points, to deposit graphite on them (and presumably improve the electrical connection)
I'm no expert, but I've heard that too - it makes logic sense - anyone got any experience of using water or pencil graphite to fix non playing keys?
@@DecPlayPiano ruclips.net/video/zrqhPdbdN1A/видео.html
Interesting - I wonder how long it lasts. Imho the problems will come sooner from the rubber pads, before the contact board. Guessing though.
I have a problem with a single C key: it plays fine several repeat notes, then the volume jumps up, and then it is silent for a few presses - and again.
I found that on the rubber contact part, the conductive paint wore off (and the contact board was dirty from it).
I plan on experimenting with salvaging some contact material from older digital stuff (rubber computer keboards? remote controls?), havent tried yet. I am not sure if resistance of the material matters (for yamaha key control board).
Graphite could work too - but it will also stick onto the borad, I doubt it would last long.
I opened my keyboard cleaned it and all but my issue is still there.
my all A & D# keys are not working, they work sometimes but then they stop working suddenly.
I tried to press the rubber bands without my keys and those notes seemed to be working fine. I think the issue could be with all of the keys or rubber bands idk .
Can you share any insights?
if cleaning doesn't work, then it could be faulty connection on the circuitboard - which unfortunately I can't help with.
@@DecPlayPiano I would like to add that it used to work fine.
I started learning again after not using piano for 3-4 months and encountered this issue.
Just wanted to add this so maybe it would give you a better idea of the situation and you can help diagnose it. Anyways, thank you for the video and help.
Hi, I got a Yamaha psr-520 some key not working I don't know how to fix it , please help me, Thanks
Hi - all I can suggest is that you follow the steps in the video and see if that fixes the problem - if not, then it might need a keyboard repair technician to look at it.
Thanks bro you saved my piano
Thanks for the great professional cleaning procedure for those contacts !!!👏
yes - they are great keyboards for portability - but I now have 4 that have dead keys - I wonder if it's a fault with the wiring / circuit board - if anyone from Yamaha is reading - can you let us know how to do a more permanent fix than cleaning the contacts? ??
@DecPlayPiano That sucks, sorry to hear about dead keys. Wonder if the contact cleaner ? I know it is not supposed to and I have used it many times but you never know.
Thanks again
@@DecPlayPiano Hi, I have a great solution! Never buy another Yama DP. I learned my lesson and went to Kawai DPs. I am about to go thru the cleaning procedure again for my 3 Yama keyboards so I can put them on Ebay and get them the hell out of here.
Btw, love the action of the Kawai's medium $ kawai es920 etc. has a good action. But their GREAT Hybrid actions start at the level of the Ca49 GFC (Grand Feel Compact Hybrid Action) and up . I just bought 2 of those for my 2 different homes because of the action that (finally) feels a DP that really does feel like an acoustic. Anyway, the dead key problems seem to be less prevalent Kawai's than the epidemic ones in the Yamas. For instance my Kawai ES8 went about 5 years without any dead keys vs an average of 2-3 years for the Yamas'.
thanks, cleaned keys on my yamaha. one key was buggy, not consistent. hope it will work better
It worked!! Fixed my a and eb keys
Glad to hear it worked for you :)
so we're not doing the crappy pecil trick to fix the keys, and just cleaning them with some deoxit? nice. do you suggest the same for the underside of the rubber bits as well?
How did you clean the rubbers that were outside of the camera?
There was no mention of him doing that. But a very mild sugar soap in warm water and soft toothbrush would suffice. If the rubber pads themselves ever give problems and cleaning doesn't work, O have use a bit of brake cleaner on a cotton bud to rub the rubber contact pads with on old remotes which got the pads working again. Just like a remote control the rubber pads can wear out, but with a very sharp blade the old ones can be carfully sliced off without cutting too deep and with flexible glue new pads applied.
Hello, I'm from Brazil I tried this on my Yamaha P95, but I forgot the order of the keybed. There are some numbers write on the top of the pieces. Do you know if I had put them in wrong position it will work as normal? (I hope write right,I speak Portuguese). Thanks for answering
I think they should work ok as long as they fit correctly - the end ones are usually different sizes - I recommend placing them in ascending order and test if they are working ok before you reassemble the case.
@@DecPlayPiano I really appreciate that! Thanks for answering
The power button is continously blinking and no sound. What might be the reason? Pls advice 🙏
Hi - sorry I can't help with this - sounds like a job for a keyboard technician.
@@DecPlayPiano ok no worries. Thanks
I live by the ocean and a couple of keys are dead. I suspect salt is on the contacts. In addition to the information on your video, is there anything else I should do to clean them? Thanks
You could try rubbing graphite from a pencil on the contacts or replacing the contact pad section (it’s not too expensive)
@@DecPlayPiano Thanks for the quick response. I will try the graphite route first. As I am in a rural area of South America, getting a contact pad section will be difficult. Any other suggestions would be appreciated.
@@donwilson974 hi don - blowing compressed air on them, cleaning them with contact cleaner (using a lint free pad) and rubbing graphite from a pencil on the contacts inside the rubber, is all I can suggest. Good luck!
I will let you know how it goes... thanks for getting back to me. Should I try a light rub with fine sandpaper to get the salt off the contact (or corrosion)?
Don Wilson I wouldn’t use sandpaper at all on contacts - I would only clean them with circuit board cleaning solution
I saved my lovely piano thanks
great to hear it helped :)
By hover do you mean use a vacuum to carefully take any dust there?
Hi Ernesto, yes by hoover- I mean vacuum out the dust
What's the spray used to clean the board
I used contact cleaner - made by WD (like WD40 but 'contact cleaner' NOT their standard oil product)
Hello Dec, thanx for the video, Qn: what is it that you are spraying (yellow bottle) to the plate?
It’s contact cleaner
@@DecPlayPiano thank you so much
Sir can u helpfix my yamaha psr e353. Keys are not simultaneously functioning special the key d. Sound is not normal compared to other keys.
jhun manuel other than cleaning the contacts and circuit board as shown in the video, I don’t know anything else to do
same problem with my psr e353, all keys are working in single tap, but everytime ive pressed 3 keys, only 2 keys works, and 1 key muted.. ive alredy tried to clean the rubber and the pcb also same problem.. yes your right its on key of d.. maybe the problem is on the circuit board.
@@refinetricks2712 I only know about cleaning the dust and dirt from the key contacts - your problem sounds like something else - sorry I don't know how to fix your problem.
Hi good night, nice sharing, please can you give a recomendation I´ve a Yamaha Digital Piano P-95B only the last Octave not sound, almost all keys works, the last octave have only 6 keys with not sound, please can you recomend me another thing to do. I cleaned all the electronic board and check the continuity in all buses. Or can you please share the schematic diagram. Thanks god bless you.
Hi sorry I don’t have technical knowledge- I only can share the info about how I clean the dust from keyboards
General question, I bought a Yamaha P35B , the headphone jack doesn't work. Any thoughts on that? Where can a new jack be purchased, and do you recommend replacing it myself. I requires soldering .
hi douglas - sorry I don't know about fixing headphone sockets
I have a yamaha portatone electronic keyboard psr 273 and i dont see a tab on the keys to pull them out so i can't clean them.. how do i solve this problem?
Some more tips. So on my keyboard, 3 keys went dead. Cleaning the landing pads and swapping the rubber membrane did not cure the problem. Looking at the circuit board, I noted that keys are wired in groups. Although the three keys were not next to each other, they were in fact part of a group. So I traced the fault to a break in the PCB track. I fixed this with a bit of soldering and the dead keys are now alive! However, all three now play louder than any others. This cannot be due to their membranes, as it is not common to all three keys. So I have more work to do!
Thanks for the tips :)
I wonder if the 3 keys play louder because of the change in connection via your soldering. Less resistance then the other keys maybe?
Hi, am trying to fix Yamaha PSR-300 key E, it's malfunctioning, you have to strike very hard before to tone picks the signal.
try cleaning the contact pads as shown in the video - sounds like dust or dirt might be interfering with the contacts
Would this explain why all the keys work except for F# and C? It's only those 2 notes but on every octave
This is the type of fault that can often be fixed by cleaning the keys as shown in the video
@@DecPlayPiano like the actual keys, the white and black pieces that you push with your fingers? That's the only thing I haven't done. I'm about to try it again.
thank-you for this video, got my key issue fixed today.
so glad it was of help to you. 😀
Hi, the captions of function buttons came off on my Ensoniq SQ2, is there a hime way to redo the text on the front panel? Thnx!
Not sure - i’ve never done that. Have you thought of using blank stickers that you write the function on?
Hi I have an issue with my npv80. When I turn on the power, everything works but after playing some time, suddenly the left sound (left speaker or left output with the jack to amplifier) is gone. After repowering the keyboard it works again but after a while it simply quites again the "left sided", sound. I have already did a factory reset but that didn't resolved it. Do you have any idea what can be the cause? The keyboard is about 6 to 7 years old and I am doubting to buy another one. Is it still worthy to repair it. I hope you can give me some advice.
Warm regards, Leo Luiten, Almere, The Netherlands
Hi Leo - sorry I don't know what that might be - if the wires to the speaker are not loose then I would recommend taking it to a keyboard repair technician
Did your rubber bands also show two central feet of different size, like mine? Just performed your actions on my Yamaha p-115 to fix dead keys, all of the keys are dead. I inserted my rubber pieces such that the large foot is south and the small one north. Maybe that was the wrong way. Please tell me if you remember!
I don't remember the rubber bands having different size feet - they had little bits that stick out, that fit into holes in the circuit board.
@@DecPlayPiano I dont mean those. In the center they have two larger notches that press on the contacts when the key is depressed. Do you know what I mean?
@@SuperInternetuser can you let me know the time location on the video when you first see the rubbers you are talking about?
@@DecPlayPiano I think 15:35 is the only time, since there we see rubber bands upside-down. Anyway, the distance to the camera is too large to make out details at this point. Though you previously referred to these notches on the underside as "contacts" and advised us to make sure no dust collects at these points.
Anyway, heres an update: I went through the whole thing again, and actually replaced the rubber bands such that now the longer notch has contact to the upper contact and vice versa. Plugged the power in, and all keys sound again!
In hindsight this makes sense, as the contact boards need some way of measuring velocity. I guess in order to do that it measures the distance between the lower and upper contacts being struck. Thats why the notches need different lenghts, so that the upper contact is struck at a delay. I guess in my case having inserted the rubber bands in wrong orientation avoided striking the upper contact, and thus without the upper contact registering anything the velocity converges to zero and there is no sound.
Anyway, thanks to your video I have no dead keys anymore! Thanks a lot!
The middle part of the rubber does have a large foot that is near the top. They are near the part that has the rubber portrusions that get inserted into the mother board. You can't put the rubber part backwards because the rubber portrusion wouldn't have anywhere to be inserted.
What is the more common reason for this keyboard to stop working?
it's usually dirt and dust on the contacts under the keys that causes the problem
@@DecPlayPiano thanks a lot
Does this work if all or most of keys are playing wrong sound ?
I've not come across that problem before - but it doesn't sound like that is caused by dirt under the keys
DecPlayPiano It’s a DJ X Yamaha and it seems like the only notes that work are the 7 lower keys the rest play notes that are the wrong tune and they will randomly be loud quiet loud quiet I was hoping to fix it since I ordered it online for $150 I could still return it probably but the shipping alone is $100 so I’m hoping I can get it fixed for reasonable price do you know where I could Find out what the problem is?
DecPlayPiano I don’t expect you to reply but thank you for sharing your video because that’s very informative and it was a very well-made video, It would’ve been nice to see up close for a little bit but then again I have a little phone screen out loud thanks for replying
Can you please tell me that all of my keyboards A keys in every octave are not giving sound when i press them but the key gives sound a little later . Can you please tell me what to do
Hi @DecPlayPiano would this work for a digital keyboard that had water seep in and stopped the keys from working?
I Don't think so as my video is designed to show how to remove dust and dirt which stop the keys working properly. Water damage is a different problem. I definitely wouldn't turn on the keyboard until it has totally dried out. If the water evaporates without causing damage then you might be ok - if not, then I would recommend taking it to a keyboard repair technician.
@9:50 the sound the rubbber nakes that woodgie noise when you pull them up! 😙
Very good and very helpful video. Thanks for your sharing.
Thank you so much. You saved me a lot of money...
glad you found it useful
Can i do this for e453keyboard
Can we use any type of pencil
yes it should work just the same on an E453
I have a YPP50 keyboard, presumably the predecessor to the YPT series. Do you know if the internals would be similar to your video?
Hi Alan, I think it might be a different type of mechanism, but the principle of removing the dust should have similar benefits
I cleaned the contacts as directed. The problem remains. It is the upper 3 F#'s and the upper 2 C notes. Since it is essentially the same (2) notes but in sequence, it might be something else. Any suggestions? Thanks.
Don Wilson have you vacuumed out the circuit board and checked that there is no dust or debris that might be causing a problem? If so, then you could try replacing the rubber contact pads.
If you put the rubber pads in upside down, the keys will be loud automatically (at least on my Kurzweil). I doubt that is the problem given the spread-out nature of those keys, but thought I'd mention it.
Hi sir,,,pls I have a much worse issue,,,the parts to be shaded pealed off at 10 places ,,how do I fix that?
Hi !! I have one keyboard ypg 235 it breaking work. It get the light only, no sound. What can I do for it.?
Hi Jonece - if there is no sound at all and the volume is up and there isn't anything plugged in the headphone socket, then it sounds like a problem that would need a keyboard technician to fix.
