Yamaha keyboard Repair - Easy fix for keys not working - or being full volume - piano 

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!

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 :)

Thanks - yea the screws are a pain!

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

so glad you found it useful :)

great - glad it helped :)

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.

fab :)

Hi Craig - so glad my video helped :) regards Declan

hi Dan glad it worked for you - thanks for the feedback

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!

My P-45 is not functioning at all. The power button is just blinking. Is this problem same as yours? What did you do?

@@nancydeluta3821 same problem. What is the solution? Pls advice

Hi Cindy - thanks for your feedback - glad the video was of help to you.

thanks for your feedback - so glad it helped :)

did you use a contact cleaner? or you just cleaned it normally?

glad it worked for you - thanks for sharing your feedback

so glad my video was of help :)

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!

Glad my video was useful

cheers Danny You are so welcome!

great - glad to hear it helped :)

Hello did this work on your e403

you are very welcome :)

great - glad it is sorted - thanks for sharing how you did it

Glad it worked for you 😊

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'.

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.

thats great thanks for the feedback

thanks for you feedback - much appreciated :)

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

glad to hear it helped - thanks for the feedback :)

glad it helped - thanks for the feedback :)

great - so glad it was of help :)

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 :)

great to hear it helped :)

thanks for the feedback

I assume the circuit board shares resources with keys according to a set pattern, which might explain this

Same here

The people in the Middle Ages were right: It’s the interval of the devil! 😝

glad you found it useful

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.

Hi john - thanks for your feedback - glad it fixed your keyboard.

Strange, every B flat and and E were suddenly not touch sensitivity for me.

Good day, can i ask if you clean every D and Ab keys? thanks in advance.

@@rainlordmanlapaz965 hi Rainlord I cleaned the whole length . Once it’s in bits , the cleaning is easy Regards John Everton

@@johneverton5342 Thanks for your help John. Hoping i can fix my keyboard now. Much appreciated

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zrqhPdbdN1A.html

Interesting - I wonder how long it lasts. Imho the problems will come sooner from the rubber pads, before the contact board. Guessing though.

Great detail - thanks for sharing

Hi Alan, I think it might be a different type of mechanism, but the principle of removing the dust should have similar benefits

I don't know about floppy disk or distortion issues unfortunately

@@DecPlayPiano Thanks for an answer regardless. ^^

It is WD-40 contact cleaner - not sure about ‘deoxit’

It’s contact cleaner

@@DecPlayPiano thank you so much

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 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’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

hi douglas - sorry I don't know about fixing headphone sockets

Yes it works for all the PSR range

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.

Not sure - i’ve never done that. Have you thought of using blank stickers that you write the function on?

Hi Ernesto, yes by hoover- I mean vacuum out the dust

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

sorry - I'm not sure what that could be

Hi sorry I don’t have technical knowledge- I only can share the info about how I clean the dust from keyboards

Thanks for the info Fred - I will add that into the video description

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

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 idea of cleaning out the dust works on most keyboards

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.
