- In this vid, we finish off the repair of the most common problem on these units. A bit labour intensive to get into, but fortunately the replacement PCBs are affordable and readily available. And the documentation for these units is exquisite!
Hey Brad, thanks so much for these 2 videos. I recently purchased a used P70 that needed new Upper and Lower Felt Stoppers. My original intent was to get in and get out but after seeing the dust and dirt inside I decided to do a full breakdown and cleaning. That's where your videos came in so handy. Although I have a P70 it's basically put together the same as the P95. One piece I was anxiously waiting for was if/how you apply grease to the inner key mechanisms. Alas, that task was not included. I'm looking at the resident grease and it's got a lot of fuss and hairs stuck in it. I would like to clean it all out but I don't see how to reapply new grease into the plastic that is connected to the hammers. Oh well. You're quite the Craftsman Brad. Your conscientious and practical approach to your work is admirable and the way I like to work myself. Also agree with your opinion concerning Yamaha. Really rare to see such detailed and illustrative documentation these days. Yamaha is definitely "Top-Shelf" when it comes to after sales customer service. I've got 2 Yamaha electric basses and now this P70. Really enjoy all of them. Thanks again Brad, Gooday'
thank you so much. Helped me save a P-95 by replacing the center sensor board. Those pins are really tricky to insert
Nice job, worth fixing it. I just sent off my istrument off for a service £400- 500. I can buy a new flute for that price but it wouldnt be silver.
Thanks buddy both your vids really useful 😊
Wow, thank you for the great video series. I am troubleshooting my P125 (water damage) and this was very helpful. The jack board and the center key contact board had severe corrosion, so I've swapped those out. I noticed minor corrosion on the ribbon cable connecting the center to the lower key contact board, but I'm not sure how to test that out.
After replacing the two boards, most of the issues are resolved but I'm left with one octave of keys that do not work - the 2nd C# through the 3rd C. I'm totally stuck how to continue debugging this! The low & high contact boards look like new. Maybe it is that ribbon cable...
You rock ❤🎉 🙏
Hi, I need to buy a sensor board and can't find any anywhere. May I ask you, where did you buy yours? I'm in the UK. Many thanks for your videos. They have been very informative.
Really nice work as usual. You should try a click bait title, “Yamaha P95 - Made with Overcooked Calamari”.
I recently took apart a crappy plastic keyboard from the thrift store. I was surprised to see the sensor boards were sitting there unprotected directly underneath the "sieve" (aka the keys.) In your video, I was very surprised to discover that a fairly decent Yamaha keyboard has the exact same issue.
In your opinion, couldn't they vastly improve the longevity of the product by putting a super-cheap cover/deflector layer over the sensor boards to keep the schmoo from accumulating? Something simple like the clear plastic cover over products sold on hanging cardboard cards. (WTF do they call those?) Wouldn't need to make a tight seal or cover 100%, just protect most of those exposed traces and solder joints.
Hello! How did you do to order a sensor board? I bought a piano P45, and suddenly some keys stoped working … I figured out that I need to replace the sensor board, but I can’t find any website to order it.
It's not available on any websites that I'm aware of. I order them from Yamaha Australia.
I like your attention to detail, is so easy to rush. Do you often change the rubber contact strips?, I’ve found they cause a lot of dead key problems as much as the pcb’s
I've only had one or two old keyboards where they wore through the conductive rubber. There are treatments available to re cover the rubber with a conductive compound, but it's only temporary at best.
excellent
Hi Brad, thanks for the really insightful pair of videos on this. I was about to start pulling mine apart when I decided I should probably find a video. Before I go, do you have any thoughts on my problem? I got one key that plays intermittently, and also the velocity responds intermittently when it does play. The key either 1) doesn’t work, 2) works correctly, or 3) works, but at max velocity. I may decide to, but I don’t really WANT to replace a board of I don’t have to. Thanks for any help!
For those who are not aware, those probably aren't Styrofoam peanuts in in the shipping carton: as Brad seems to allude; they are most likely made of cornstarch and are therefore compostable. They'll shrink down to almost nothing if they get wet. Actual Styrofoam peanuts are horrid little things ---- non-recyclable and terrible for the environment, provide little protection from shipping damage, and generate static cling, which is bad for microprocessors and static-sensitive electronics. They should be banned worldwide. (BTW, a shop-vac is usefull for sucking the peanuts out of a large box, as long as there aren't any tubes or small parts in the carton). PS, the pink bubble wrap is supposed to be at least marginally ESD safe, but the really good stuff has a metallic or carbon impregnation or coating.
I threw a shitload of them on the lawn today to test it out, and as you mentioned, once I hosed them down for a bit, they literally disappeared and melted into the grass. I'll do this from now on! If only they could use this technology for shipping speakers instead of the expanded polyurethane foam in a polyethylene bag like Eminence do for all their drivers.
@@BradsGuitarGarage I was gonna make the same comment about the packing material. I just throw them in the sink and rinse them down to nothing.
Oh, and great video.
Hey how much do the replacements cost and is it possible to order from EU?
Find your local Yamaha distributor and send the spares dept an email.
@@BradsGuitarGarage Thanks 🙂
Hey, great video Brad! Have the same problem with my Yamaha P105. What site did you order the sensor boards from? Can't seem to find any in Australia
Hi Malcolm, contact Yamaha Australia and get them direct. Contact me via email for more info if required.
@@BradsGuitarGarage Thank you!
I’d like to slap the Yamaha design engineer who thought it was a good idea to bury all these parts under a billion screws. 😊
Just bought P-95 B a day ago. One key was sticking a little at first. I marked i, so when i open it i know where to start. Will they get stiff for just sitting up for a long time ? What does the ((( B ))) in the P-95 B stand for? What is the difference. I did get a peddle and double X stand with it. P.S. All of this started with LADYVA 's Boogie Woogie piano video's. I tried some of the cords with my midsize key Yamaha keyboard. Midsize keys way too small for me. Started looking for fullsize weighted keys. Here i am with the P-95. P.S. again. The keys way on the end are really useless for sound and sound quality. Is this the norm ? That is for all instrument sounds on this keyboard.
None of that is normal.
Sounds like your unit has been abused pretty badly, as they're very sturdy and reliable units.
Is nifty equivalent to Ajax spray and wipe? Or should I go buy some 😊
No idea where you are, mate.
The Ajax stuff in Australia is nothing like it though, I can confirm.
It's quite caustic and I'd never use it for anything in our wheelhouse other than the kitchen cooktop.
Would it be safe to dunk the sections of keys into an ultrasonic cleaner for a few minutes?
That would be an option if I had one!
Wouldn't be effective on the labels or the big chunks though.
