PS4 Diagnose Faulty Panasonic MN86471A HDMI Encoder IC Chip Tutorial (WLOD)
HTML-код
- Опубликовано: 27 авг 2024
- This video goes through how you can diagnose and repair a faulty Panasonic MN86471A HDMI Encoder IC chip on your PlayStation 4 (PS4) video games console.
This chip can fail and cause picture artifacts, snow, flickering picture, dropped audio and black screens among other issues.
Man you the best!!! I always wanted to learn microsolder. My hdmi port broke on mine 1 year ago and i just so happen to run into 1 of ur videos and it was downhill from there. Ive bought 16 used PS4s so far and successfully repaired 10. Im looking forward to doing my first APU as soon as i can afford better tools. Im working with a cheap walmart solder gun and a $10 microscope i ordered from wish. My first 2 repairs were with a magnifying glass taped to my phone camera lol. Thanks Andrew
Very thorough tutorial! Almost gives me the confidence to try this repair myself.
Thank you.
Hi i have a ps4 white light problem and need advice.
So i traded a faulty xbox one original for a supposed faulty ps4 original from a person that fixes consoles that wanted the Xbox for spares.
So on the day i got home with the ps4 i used my ps3 cables to power it on and it miraculously powered on which surprised me as the controller was connected properly using the usb cable.
But i saw the screen flash black then back to the home screen which i didn't know what is was then it did it once more and was displaying perfectly.
After about 5 mins of waiting for it too show some errors or switching off because i did not expect it to work i plugged in my usb speakers to the other usb port on the front while the controller was plugged in.
That was when the screen went black instantly. I didn't know what happened and pressed the eject button and a copy of GTA 5 came out which means the console was still powered on.
When i plug the controller and speakers in on my ps3 super slim at the same time is says too many devices drawing power something like that.
So i think it drew too much power on the ps4 and caused a wlod on the ps4.
Im trying to do a home repair with minimal tools and if you could give me some idea of what the usb ports could have shorted eg a transistor or fuses or something.
It still powers on and everything but that was the defining factor i think that contributed to the white light of death.
Any recommendations would help as ive watched a lot of RUclips videos and most are the ic chip or some transistor .
Its a original ps4 with wlod 1116A
love the idea of soldering long pins or needles to the tester tips
all of your videos are extremely helpful! I replaced my first hdmi port successfully the other day thanks to your vids. thank you for sharing your knowledge
Thank you and congratulations on the successful repair :-)
I need this done to mine. I just recently dropped my ps4 off at the local repair guy to have fixed knowing that I had this same problem. When I explained the problem and my suspension of what it could be, I was reinsured it shouldn't be a problem to repair. Well guess what? Got a phone call letting me know they replaced the hdmi port only to have the same issues and they do not have a in house person to replace the i.c. and apparently there is not a person in the whole city of Austin that can fix this problem. So I guess I'm doing it myself. Thanks for the excellent video guide! I really would love to send it to you for repair..
Would have been nice to capture the HDMI port testing on camera, although I suspect this is done this way intentionally so not to give away tricks of your business or because it's hard to get everything on camera AND the DMM.
Glad you showed testing continuity of the video filters to the chip itself though, helped me verify my HDMI video filters as ok.
I replaced my HDMI encoder chip and I now have video and sound...Many thanks for this and all your other content, you have shared and helped me and so many others, you do great things :)
Nicely done! Finally I can realize which is the problem with my PS4.
Thanks. You are very good at what you do and at explaining it to others. Keep it up. Thanks to you, I got a blue light of death (long version) off ebay going with the 3 washers trick only to find white light of death after that. I fixed it by watching your videos and changing the hdmi encoder. I second your comment about hot air stations. My trusty Aoyue 968A+ got the old hdmi port out (it fell out whilst taking the shield off the hdmi ic on the other side of the board lol) but could not get the board hot enough to allow for aligning the hdmi port pins with a new port. Thankfully, the old port was OK and the previous owner had given up at that stage. Cheers.
Excellent video mate, I've just learnt so much from this 47 minutes. I've got just the board here to try all this out on too. Thanks again
You're welcome and good luck!
Howd it go?
Fantastic job done highly confidently. Excellent teaching as well. Good on you. Thanks.
Thank you :-)
Andrew, your video's are great. You are definitely someone who never gives up, like that ! Just had a ps4 with WLOD and flikkering black screen at random times
- under microscope I saw 1 pin moved about 1mm inside, so that one needed replacement
- replaced HDMI port, same problem
- replaced HDMI IC, same problem
- gone through your video's, measured everything again, all GOOD, so eventually concluded that the NEW HDMI IC chip was defected
- replaced HDMI IC by another new one, and BOOM, working !
Satisfied, but still thinking, how could that happen ? Never seen a new defective HDMI IC chip, did you ?
Had one before now but only the one thankfully. Not bad going really in the circumstances lol :-)
Really annoying though as it does leave you scratching your head for a while:-)
Andrew Paul Thinking about desoldering and soldering back the hdmi Ic's with my rework machine, which I use for reballing apu's for blod ps4's. Also Thinking about a test method to test new hdmi ic's, suspicious hdmi Ic on boards and desoldered hdmi ic's. When I desolder and solder back a hdmi Ic with my rework machine, i can make a video, if you like.
I scratched my head actually all the time yesterday, when It did not work after replacing the Ic for the first time. Left my girlfriends house on sunday and said: I need to get back to work, I need to fix It.
Thanks for showing this. Now I know I don't have the tools or the patience for this. I'll leave this repair up to the professionals.
always say around here, that in the USA! it's always better to buy a new one than fix an old one! because of the facilities to buy electronics! already here in Brazil! we tie with wire! we put ribbons, we stick! or we make the most infinite exotic repairs, when we have no parts! I liked the way you are perfectionist in replacing the aligned resistors etc! well professional your work!
Your videos are really helpful explains alot how to repair and check if any damage
its very helpful to have such a detailed tutorial, without your video I wouldn't have found anything concerning my problem. Keep it going :D
you make it look so easy! took me a few hours to solder the new IC chip but was a success. thank you for this great video!
Hi
I want to ask you did
Need a microscope to solder the new chip ?
It certainly helps, but it's not a definite requirement.
@@AndrewPaul thanks a lot
subscribed
Thanks! :)
Thanks so much, you have helped me yet again! This is educational but I enjoy watching so much. I appreciate that you show the whole process rather than editing everything to make it more appealing to the masses. Keep the great content coming and thanks from Australia.
Great video! Keep on going mate! Now I'm going to fix PS4 that used to have some artifacts (screen goes red, and customer reporting also some sound problems which I didn't noticed) while playing games. What I think it can be faulty HDMI encoder IC. Hopefully the GPU is OK.
real top marks for the way you run through the fault finding process .,very interesting
Cheers mate.
Thanks for this video!!!!! I successfully diagnosed and replaced the IC chip in one of ours!
There is a very fine line between not enough & too much heat/air flow. I like to use a temperature controlled heat gun, to preheat the board, & also use low temp thermal alloy, known as "Chip Quick" to help loosen the pins of the chip, as well as the shield. Often, I use no hot air station, just the heat gun. If the chip has a thermal pad underneath, then I break out the air station, but just to melt the solder pad under the chip. I see that this chip has no pad.
I really like this kind of videos, I find them very interesting and entertaining
Ill be doing this on my ps3 this weekend. I like the method you used for soldering the new chip on. Most seem to put the chip on bare traces(no solder), then put a big glob of solder or solder paste to one side & drag solder all the way around. May work but it looks easier in vids & its easy to mess up doing it that way imo.
I just had a PANASONIC MN8746A replaced and now the image is seen with a little snow in the background.
All the best
Check for loose pins / dry joints on the encoder legs.
Use solder paste to tin the pads instead of regular solder. It lays down better, and most of the time you can lay the chip on it, heat and it lays down a nice filet.
I'll apply this to my projector that I bought many years ago, but never got the hdmi to work. Thank you
nice video ... if 4 chokes are dead after power surge, are there any chances that IC survived ? can i just bypass chokes to test IC and then replace them if IC is OK ? i have this ps4 that died after power surge ... it was completly dead and after i have replaced power supply with ATX PS and now it has WLOD, cheking those chokes like you did shows all 4 chokes are dead ...
Thanks Andrew this video helped me fix a faulty hdmi ps4.
Congratulations on the successful repair and happy gaming :-)

Awesome work Andy thanks for the advice given yesterday its much appreciated
No problem mate, cheers.
No worries I've sent you another message on eBay about that us console if you could take a look when you get sec it would be appreciated.
Hello from France! Thank you for your videos, they are very helpful! However, I messed up a bit trying to replace the Panasonic chip. Before i even got to that part, I removed a component when I took off the lid/heatsink. I don't know the value of that component (a resistor no doubt), and I wish I could send you a picture, that is, if you have the time to help me out. In any case, thank you again for sharing your experience with such clarity!
Au final, tu as réussi à la ressusciter la console ?
Hi Andrew,
I'm new to repairing but I've taken on the challenge of repairing a PS4 original, I found (SAB-001 model). Tested the HDMI pins and pins 1-12 (all the data pins) are shorting to ground. Is this normal? Everything else around it looks fine.
The IC encoder side had some sticky residue on it so is this likely a bad IC?
Thank you so much for the video! It's been amazingly useful! Keep up the excellent explanations!
Hopefully I wont have to replace the IC chip, but if I do, Thanks for this video!
Sadly, the person who had the ps4 before me had attempted the repair and caused some pad damage and I wasnt able to preform the repair. :(
Hi Andrew, thanks for all your videos, I have to say they are really useful. I'm facing an issue with my PS4 Pro console, when I turn on the console it says Too Many Devices connected. Ethernet Port is dead, Usb Ports are dead as well, Sony suggested to reset the console, and now I have a beautiful reseted console without being able to sync the controllers.
Do you know Is there a way to sync the controllers in a hacked/cracked way so I can Sync them and use the console. Or do you know which chip needs to be replaced based on your experiencie?, I want to try to fix it by my self, since I was told that the board must be replaced, so! Thanks in advance!
could you also tell where you place the black pin and red pin of the voltmeter when testing the Chip and also when testing the Port.
when testing continuity it doesn't matter.
Hello Andrew! Thanks a lot for this video first of all! But what I would like to know is it necessary to put back the metal clip and how do you put it back?
First testing from the pins to the alternates had me confused as I couldn’t really see what he was doing and my motherboard is completely different from that one. Would really like to test everything before I buy a new chip. Also what are you putting on the chip before removing it. And what temperatures are best for removing the chip. Mine didn’t have a cover over the chip and it’s directly behind the port on the same side.
Im having flickering image to no image, then it comes back then artifact then its goes to normal. Then backs with the cycle.
Do you think i have the same problem with hdmi pansonic ic?
Hello there, would you be able to help me with something please, I think my PS4 has a board problem, when I insert a game or dvd the green goes or fuzzy with green dots, I have tried different hdmi cables factory reset etc but no luck
Awesome video!! just passing trough this can I ask what was the air flow and heat you use aswell as the flux I'm practicing with other boards before doing this but my flow and flux aren't helping.
Great video, u shed light on my problem which is no picture or sound... Even in safe mode boot... Do u think I have same problem?
Very possibly. Check the condition of the HDMI port first - if all good then this is the most likely cause.
Andrew Paul
Ur a pcb savant btw... Yeah HDMI port looks good no pins out of place
A real techie...enjoy your videos...I would love togain access to some schematics,,,if you have them
Wouldn't we all ha ha! Sadly they're tucked away nicely in Sony's vaults :-(
Many thanks though and glad you enjoy the content! :-)
what about the reading on the caps near the hdmi ic ?
I feel we should do a crowd fund to get you a new heat proof mat lol my ocd would kill me if that was mine.
Wow, now this is learning. !
I love watching your videos. Just wondered what flux and solder you use? My de-soldering braid seems to solder itself to the point I'm de-soldering so thought it maybe my flux?
Flux is Amtech NC-559. Solder is just a generic 60/40 tin/lead with Rosin core flux.
Could there be another issue to the no signal problem other than hdmi port and hdmi encoder ic chip? (How likely it's another issue other than this two?)
This made it easy, checked my connections, still no video, nor will it go into safe mode
Sony really should have done a recall for this. My first PS4 died after a few months with this issue and under warranty it was sent back. Lost in transit so the store just gave me a new one. The replacement PS4 has had the exact same issue many years later. So I'm 2 for 2.
hi, sorry you can help my please, whats the name of 4 chip down chip mn86471a... , in the video you speak about this in 27:03 -27:19...thank you adrew paul
so where does one get a chip, trying to prove myself to people very confident i have the skills to replace it i just need to know a reliable source to get one
Hey Andrew! first off, great vids man! absolutely love them. Question, Have you worked on any SAC-001 boards? They are the newer slimmer boards. I've got a WLOD that seriously has me stumped. HDMI port has been replaced, i checked the 4 x optoisolators and they seem fine... just wondering if you've seen anything like this
+Daniel Wynne I have but not for this issue. I've got a perpetual wlod video coming in the next week which might be of interest and might throw some light onto a possible solution for the SAC revision board too. Cheers.
Sounds good m8! I've just ordered a replacement MN864729 from China. hopefully replacing this will fix it. i'll let you know if it does.
Cheers!
Thank You Andrew! I revive a ps4 with same problem!
My pleasure :)
what is that goop he uses on the motherboard im gonna have to get some?
Hi. Can i use the MN86471A instead of MN864729? Are those two compatibles with each other? Thanks in advance
Hey, keep up the good work! Do you think it would be possible to post the HDMI pinout without using red on green(maybe blue)? I'm colorblind and wasn't able to see anything.
Sure thing mate I'll see what I can do :-)
Hello. I'm starting to learn, to repair things. I have a ps4 1116a, which does not give an image. I did as you explained, but even so, there is still no picture. I noticed that near the hdmi encoder, as you said, it has 4 components, all in a row. They seem to me to be capacitors and resistors, but I don't know. Can you tell if this affects anything, in not giving an image? The components are the ones you mentioned.
Hello! I would like to know if you replaced back the metal panel/heatsink(don't know if it was?) over the chip
Thanks mate for sharing and for your time!
No problem :-)
Are the IC encoder pinout the same on the PS3 slim?
Hey Andrew, I appreciate your videos very much! I have a PS4 with no video and I’m at a loss. I’ve tried everything in your videos with still no picture! Could you do a video of going over all the caps and diodes and the values of them on the hdmi circuit? Thanks Andrew
Wazzup bro , My beloved 1st generation ps3 slim having a problem, it stuck at 480p at HDMI. I resolder the PS3 HDMI port and it not fix the problem, do you think it's the panasonic MN8647091 hdmi transmitter is the problem? it can't recognize 720p 1080i and 1080p stuck at 480p only. AV multi out is functioning normal.
+playstation2bigs Hi mate - yes that's probably your issue.
+Andrew Paul do you think it's a cold solder joint? or replace the whole i.c. ?
+playstation2bigs It might be worth doing a drag soldering job on the IC to see if you can get rid of a cold joint or two but if it's anything like the MN86471A found in the PS4 then dropping of the HD resolutions indicate an internal fault and will require a replacement of the IC. Cheers.
Thank you very much Andrew more power
+playstation2bigs That's what happend to my PS4 3 weeks ago!
mofos wanted 200$ to fix it. I rather pay 400 for a new one with 3 years warranty.
Hi, sorry to bother you under an old video. I have two main questions:
1. If my PS4 as a WLOD problem, can I be sure it's a Encoder IC problem?
2. What heat gun are you using? How many Watt can it emit?
Thank you!
I'm brazilian! Your videos have helped me a lot! I'm curious to know how much it would cost a repair job like this in the US?
First of all thank u for your help. Sadly i have another doubt. Checking on the internet for the Panasonic chip MN86471A i found out that there are lots of models with various prices of the same chip. May you tell me whats the difference ? Quality of the component? it seem strange because every chip is sold by panasonic. Of course im not an expert , thanks for your support.
It's just re-sellers trying to maximise profits on the parts as seems to be common these days sadly so prices naturally fluctuate wildly. Go for the cheapest reliably rated seller you can find.
Thank you so much!!
You're welcome. :-)
Hi Niccolò Im from Italy too. I would to do the same repair on my old ps3 slim but i'm a noo so I need some advices. Could you help me? If yes, could you share an email address / honagout to have a chat someday? Thanks a lot
Hello Sir, I have PS4 slim, HDMI port is ok. but there is no image on the tv. i dissembled it, is there any other reason , other than This Chip? its number is MN864729
great videos indeed very helpful..thx
i wonder u can help here with with a issue..im in repair service...yesterday after another hdmi replacement of the hdmi ic..my console is not powering at all no beep too..everything seems prety clean..i removed the ic completely still no power..pls advice thanks
They should make the HDMI port like a USB thumb drive to be easily remove.
and an extra slot in case on slot gets damage, so we can just switch the HDMI output to the other side.
With the encoder inside eventually as a one part easy replace.
that defeats the purpose of a motherboard. it might make repair harder but makes making the ps4 easier because everything is soldered on the motherboard
have you ever had a ps4 never worked on where you changed hdmi port and hdmi ic but still no video signal, and ps4 doesn't beep properly to enter safe mode? but the system seems to turn on properly with the white light? just no safe mode with hiding down power button, just shuts off
Can an encoder be causing a black screen that makes the TV think it has signal but still has full audio?
Yes it can.
I just replaced the hdmi port, witch didnt seem broken to me, but i did it anyway. That didnt work and its not picking up on the TV. Is that an encoder problem?
21:45 Need to trace the filters before changing the ic just to be safe! U may be getting rid of a good ic for nothing if there's no continuity on your filters.
Do you have another video in which I can see where do you place the pins of the Voltmeter it is difficult to see with your hands covering the area. Thanks a lot.
hi Andrew
Love your Videos.
I have the famous WLOD, replaced the HDMI chip TWICE and still no joy, I have managed to have another look at my PS4 mainboard , and to my surprise I see that I have an smd component missing. The missing component is located above the HDMI chip on the top right-hand corner. it the second smd component if you looking form the extreme right-hand side just above the HDMI chip. I would like to know what component it is resistor/cap/diode, and the value of the component.
Please would you check up on a donor board so that I can get the components or at least the type and value for replacement.
Looking forward for your response
Many Thanks
ash
Hy,one of small smd from 2 which are in front of the IC was missing,I try to replace with another but not working,any information?
Hi Andrew, I've had the exact same issue as appears in your video although the tech shop i left it in to be fixed with had it for 3 weeks said its beyond repair. Do you do repairs in London or have any contacts for repair in London?
Hi Ciaran,
I'm based in West Yorkshire but I accept mail-in repairs from all across the UK and EU. If you want to send your machine in for inspection / quote then drop me an email to ytandrewpaul@outlook.com and we can arrange that for you. Many thanks.
Just emailed you there mate thanks
Hi Andrew, I have replaced a HDMI transmitter chip, but for some reason only getting Sound output on the HDMI.... would you have any idea what would be next suspect? HDMI port looks fine, so i haven't replaced that yet.....
Sound but no image is typically down to a bad encoder, however as you've just changed it I'd be more inclined to suspect a loose / bridged pin. Give them all the 'nudge' test with a tweezer blade and see if you can get any to move and resolder them if they do. If you've any shorts / bridges between pins then these will need to be removed. If that all looks good, check the EMI filters to ensure they're within spec.
@@AndrewPaul i did check all the pins, pretty sure there is no bridging or loose pins though i will check again once more just to be damn well certain ! I continuity tested the 4 filters, they all came out fine.... just like how you did it in this video. Pretty stumped to be honest, the sounds on but no ones home ! lol.
@@AndrewPaul Thanks, was one of the EMI Filters! Brilliant!
nice man ur really nice, we need more people like you instead of useless fortnite players and streamers :D
Could you replay to me and tell me what tools would i need to do this myself
quick question i actually replaced my internal fan awhile back and about a 6 weeks later i fell asleep watching you tube on console woke and put it in sleep mode when i got home and tried turn it on sometime it starts to run and then shuts off other times it cuts on normally but i get no picture or sound any idea what might be causing this.
Hi Andrew, let me first compliment you on your very professional work !!!
it helped me a lot.
I have this problem where i changed the hdmi port but still no signal, when measuring the pins direct to the filters in front of the ic, all ok.
but when i measure from the via points to filters nothing happends.
might have any indications for me ?
Thanks in advance pal !
Hi,Have you scraped the vias back to expose the copper before attempting to check them for continuity? Cheers.
Hello Andrew, no i didnt, but i think if the pads to the filters have continuity the vias will be ok, right ?
Now the telly doesnt give me the "NO signal" indication but rather black screen and if i play around with the hdmi i sometimes get a green snowy image, tried also booting in safe mode but the same..
Hi pal great video I’ve just replaced a hdmi port and it’s just white light no image on the tv I’ve gone through your steps and found the 2nd and 3rd filter by the control chip doesn’t have any continuity so I’m guessing replace those and hopefully will work
Did you manage to get this issue fixed I have a PS4 here with similar issues swapped hdmi port and also IC from a scrap board i don't think the issue on this one is the IC but wanted to do it anyways for practice. I have not tested the filters yet as have not got fine enough multimeter probes yet just borrowed some that may be pointed enough going to test the filters tonight thanks for the videos Andrew very educational
Hello Andrew, I have a WLOD ps3 with no sceen output, safe mode not possible. Replaced the HDMI IC chip and after that the screen output was a noisy red. And when I moved the hdmi cable (good one) the screen went intermittently from red to nothing, so I also replaced the HDMI port. Now the screen output is constantly noisy red. Tested the 4 video filters next to the HDMI IC and they are all good. HDMI port pinout is good (checked your other video). Also the connection of the 8 points (video filter points) with top and bottom mobo are good. What do you think is the problem here ?
+ProConsoles Was the IC a known good part? Is it possible to test it on another board?
+Andrew Paul It was a brand new one actually. But I do have a scrap board with a good one on it. Can desolder that one and use it for this board. Can't stand this, it has not been fixed. After diner I will continue and finish this ps4. Tomorrow the customer flies back home in the US. I soldered on the HDMI with drag soldering with JBC soldering iron on 365C. Need to find out test points first. Besides thanks a lot for your very fast response ! :-)
No problem, and please let me know how you go :)
+Andrew Paul Replaced the HDMI IC chip, by a HDMI IC chip I desoldered from a scrap board and ....... again no screen output. Somehow this HDMI chip was not good, I hope and suppose. Tomorrow I will take again, a new HDMI IC chip and post the results. I like to mention that I desolder the HDMI IC chip somehow different, then how you do it. I use low melt solder to lower the melting point from 217C to 150C, then use hot air to desolder the IC chip. I think it is a little bit more safe. Do not want to damage the surrounding components.
+ProConsoles Soldered in a new HDMI IC and still the same problem. Pin 13 of HDMI connector does not have a low resistence. All connections from end of HDMI cable to the test points are good, video filters are good. Nothing of the soldered connections have shorts. Still WLOD without screen output.
Andrew, Wonderful video. I am hoping you might give me an idea as to the next step for me. I replaced a damaged HDMI Port and all the pins test well to the IC and to the test connection points on the board. When I put it all back together I got the WLOD. I went into safe mode and found that the unit displays well in 480P , but it doesn't want to work with any higher resolution. Does this still sound like an encoder chip problem to you? I will replace it if needed, I just didn't want to order one in before I exhaust all options. Thank you for any input.
Hi Rick, yes mate - that'll be an encoder IC failure.
@@AndrewPaul Thank you for the input, I will replace the IC and give you an update.
@@AndrewPaul Hello Andrew, I replaced the HDMI IC and it still will not give me anything above 480P. I double-checked everything and I am lost as to where to go next. Any Ideas where I should look would be appreciated.
Where did the new chip come from?
@@AndrewPaul I got it from esourceparts.ca . I get many parts from them and never had any trouble in the past. Do you think it may be a faulty chip? Is there a test I can do to confirm the chip is faulty. Again, I appreciate your input.
Do you know if that metal plate above the video chip is important? because mine came without it, it was used
Hi,
It's an RF shield - not vitally important in most situations - I've seen many machines with them left off over the years and they've been fine. As always though if you can put it back, do.
@@AndrewPaul I was worried that the ps4 would not work because of the lack of that thing. Thanks for answering me :)
Hi Andrew! Thanks for the vid. I measured the path from the chip to the filters and figured out that all pins going to the HDMI are shortened to ground. There is no physical damage on the port. I am consider changing the chip. What do you think? Regards, Erwin
I'd bet that's a very good possibility. Remove the current IC and see if the shorts disappear. If they do, change the IC.
Thanks Andrew! I changed the HDMI IC and the shorts disappeared. As the metal shield around the chip was very hard to remove, I cut it away. Therefore, I tested the PS4 without the metal shield on the HDMI chip.
The TV is getting a signal now, but still there is no picture. You can observe some noise (similar to the noise of an analog TV receiver) when the TV is getting the HDMI signal, before the TV is turning black.
So, my main question is: Also without the metal shield, I should get a better signal, shouldn’t I? (I want to avoid placing the metal shield there again, it was a pain removing it already 😊 )
Regards,Erwin
please tell me in the bunch of hdmi is where the two resistor track is from the third diode for continuity can rings and shows 22 ohms is this normal ?vipal also sveneti and 22 ohms ?there is soprotivlenie should be sab 001 was replaced with the controller Panasonic video was the white snow and the reddish then all sound disappeared'm sorry for my English bad
hey i hav a question if this was blown wud it cause a green tint on the screen? if i change hdmi inputs i get a green tint on my screen
Hi Andrew great video followed your video's and decided with your guide to change Panasonic IC chip but regrettably as everything was going so well, after removing the IC chip I noticed the four filters have come off. What's the best way to put them back on or am I screwed? :-(
Thanks
+Naz Nadeem just pop them back on - they're not directional so just line them up back on their pads, hold them with some tweezers while they reattach. Once they're all back on turn the airflow down a bit, add flux and reflow. They'll all line back up perfectly and you should hopefully be good to go!
+Andrew Paul Thanks mate, that's what I thought but it's reassuring with your guidance. Much appreciated will give it a bash
+Andrew Paul sorry mate where can I get more filters I seem to of lost one :-(
scrap boards are the best bet - PS3s have the same filters and scrap PS3 boards are pennies on eBay so just drop for one of these and swap them back over - you'll have a few spare then too :)
+Andrew Paul Just for your info I found an article on the net regarding the filters and one guy used a 30 guage wire to make a jumper connection, as long as it works that works for me :-)
Thanks Buddy for your help
Amazing video as usual Andrew! Do you have a diagram of where to check the continuity of each hdmi pin to the various places on the board please, I cant see where you test each one on the board in the video?
Sure thing mate:

Thank you Andrew, that is much appreciated :)
Where to find those at good price?
I was using a vga to hdmi convertor on my ps4 to use with my old monitor,coverter uses a 5 v adaptor but i accidentally plugged in 9v one,after that my PlayStation was being detacted on my tv as giving a signal but after a while it had no signal at all, could it be that its just the hdmi port itself and not the ic chip?
One question
My PS4 when running the screen is black console light White and on screen unknown input
I dont know if i recieve a faulty replacement, but before theres was continuity betwen in the 4 filters, i mean each pin of them. So i took off the ic and the short was gone. So i solder the replacement and theres continuity in the 3rd filter. Thats normal? Can you tell me if i have a faulty replacement? Thanks
Sounds like you either have a small bridge between the pins (they can bridge to the rear and are hard to spot without a scope) or a faulty replacement.
I desolder it again and clean it. Still there (in the ic) so I guess its a faulty one...
Nice vid mate,
I have question: My ps4 goes on into a white light, so no image. When i go into safe mode, it gives a screen for 1 second and after that the screen goes black again.
I have replaced the hdmi port, but no succes. Do you think it might be the Retimer on this board? Thanks in advance
What temperature do you have your soldering iron set to for applying the leaded solder to the pads?
+Chesley McDaniel It's self-regulating so I have no control over it. The iron calculates the needed temperature by measuring the heat draw across the tip when touched to place where the joint is required - so I don't know what temperature it's using. Cheers.
+Andrew Paul Oh okay, fancy! :) Thanks anyways.
+Chesley McDaniel No probs - however, my TP9 tip has blown this last week and I'm waiting for a replacement so I'm back using my old solder station for now for fine work. To drag solder effectively that station has to be set to 485 Celsius.
+Andrew Paul Thank you for that. I wouldn't have expected it would need to be that hot. Now I see why I was having trouble. My iron only reaches 450 Celsius but I was afraid to turn it up that much out of fear that it might fry the HDMI chip. Have been having hell with my ps4, pulled a pad where the Panasonic HDMI chip mounts (due to having a much to large hot air gun and being afraid of burning up the MOBO), so I attached a very small jumper wire to the proper circuit but still have WLOD. Now after several attempts, I broke off a leg on the Panasonic chip where I had the jumper wire.
Thanx Andrew for this tutorial. in the console i fixed by removing the four filters, i checked them before and they looked fine with continuity test, but i had to remove them, i really worked a lot on that console, so not 100% sure if removing the filters solved my issue.
i bought the jovy i40 solder and it is in the way now, may needs two weeks to arrive if everything went ok.
looking for your next video and if you have a PS4 that does not sync the controller at all except in safe mode, please care to share your thoughts :) it driving me nuts
I've one on the way I think mate - I'll be sure to cover it if (when) it arrives :-)
+Andrew Paul Thanx Paul, do you think that this tip www.aliexpress.com/item/Free-Shipping-T12-1403-spade-scraper-spatula-soldering-iron-tip-for-HAKKO-FX-951-soldering-station/827249593.html will work on the Isolder40, i saw in ebay it may does, but not sure, what do you think?
It looks like it might but without seeing the bottom edge its hard to confirm. I am aware of people using Hakko tips with the iSolder40 though so I'd guess it'll be OK. :-)
U are a legend
What you set temperature air hot at 🤔
480C @ 100l/min
Awesome videos, really nice work and explained thoroughly. Have a nice case here myself, CUH1116. White led. HDMI port looked okay, but used your video to check every pin. No problems. Checked the diodes, all around 0.500-0.600, so okay as well.
No shorts on the topside caps, decided to replace the HDMI IC nevertheless. No dice, still white led. Removed all 4 filters and replaced them with wires, checked continuity to the IC pins, all ok. Still white led.
Any clues to what I could check more apart from these ? I doubt the IC is bad (or even that the original one was bad), but since the port itself is pristine as well I'm really baffled here. Failing GPU ?
Check TH2001 and replace if no continuity.
Can you use a MN8647429 instead of MN86471A Chip?
No, the two are completely different.
