- This Video Highlights the Process of disassembling and replacing worn rubber contact strips in a Yamaha P-515 Digital Piano.
I repaired a dead C#5 key. The sensors were OK but it needed a new circuit board (the one in the middle). Note that on mine you must have the head phone circuit board plugged in to produce sound (unlike the video).
thanks so much! so clear and precise. dead D5 no more! q-tip and rubbing alcohol did the trick. had to do it after work too, took about 2hrs (it/s 1:30am here); You know d5 is an end piece in the rubber strip...i bet those are the first ones to go as they get uneven wear...
Great video. I will attempt the same repair this week on mine. One recommendation. Consider wearing cleaning gloves and taking other precautions to maintain a dirt free environment.
Thank you for this video I did it first try 2 1/2 hours.
My 515 is 4yrs old I play 2-3 hrs a day
1 key just started velocity problems recently .
Thank you very much! You helped me a lot! I had a problem with C4. It was too loud, and the reason was the dust that had accumulated over 5 years. Now I cleaned all rubbers and all notes sounds right! This wouldn't have been possible without your guide. Thank you!
Great video! Need to cleanout a key on my cp88, no video and yamahas are built like safety boxes. Nords are way easier.
I want to know if replacing the plastic shells on both sides requires removing the screws at the bottom, which is the shell removed in the first step of disassembly, or can it be removed directly? Thank you!
I believe you can just remove the bottom side screws and slide those side shells off. Hope this helps!
Thank you for posting the video. Using it, I just successfully completed the cleanup of my P-515, including replacing some of the contact strips, and wanted to share a practical tip. To hold the keys in their un-pushed position while the keyboard is upside-down, use a bar (could be a 1/4 inch dowel, the length of the whole keyboard) to insert it right through the counterweights. This will allow you to place the contact strips easily. To place the bar or to pull it out, put the keyboard down in its normal position. Then, flip the keyboard with the bar in it to work on the contact strips.
Yes this sounds like a great idea. Thanks!
Brilliant video, thanks!!!
Didn’t;t quite need to go as in-depth as you did - my issue was a broken USB-A port on the back after my son tripped over the cable and yanked it, snapping the port internally….and the n it wouldn;t connect by cable for SmartPianist. One the top control panel was off, it was easy enough to remove the one single circuit board with the connector and de-solder the broken connector and replace it with a new one which cost pennies. All working well now. Spot on!
hi, was following your video and it was very helpful! I put the keyboard back together after moving the rubber contacts/cleaning. It turns on but no sound now 😢
Do you have any ideas/tips? Would this likely be forgetting to connect some cable?
figured it out 😂 was really panicking for a few days. The 5 cables, if any of them are disconnected could result in the keyboard turning on but no sound. Turns out not so easy to break even if you're bad at this like me! Just make sure to connect them, some can come loose accidentally.
Cheers thanks for video a ton.
Is it correct to assume that there is no adjustability for small positioning of the white keys themselves relative to the gaps between the keys? Reason I ask is that on my P515, there is a bit of inconsistency with the gaps between the white keys across the keyboard, and it would be nice if there was some adjustability to even these out. It's not pronounced enough to cause two adjacent keys to touch, but it's close in a few places. Thanks for the video!
I don't think there is a way to adjust them but I haven't actually tried to do that.
I just did it... Some keys had full velocity and I had to stick to harpsichord or organ sounds (instead of my beloved Bösendorfer) so I checked and cleaned the rubber bands that were full of cat hair. No replacement needed but i guess I will order parts just in case. Those rubber bands are really difficult to put back since you have to keep the keys pressed (or depressed, not sure). This was by far the most tricky part and I was quite anxious to test my piano (and afraid it would be completely unplayable). It works OK now, I'm relieved, so thanks a lot for your work.
Oh, and I guess I will cover the keys now. Messy beast.
Lol yes I could definitely see animal fur making an impact on the playability. The trick I found for replacing those rubber strips was basically to prop the keyboard up where there was no weight on the keys. That made it easier to get the contacts in place along with the circuit boards. Glad you were able to fix it! Cheers.
Very useful video. Made taking my P515 apart so much easier with your tips and also gave me the part number to order. So I repalced the rubber contacts as you described. Electric screwdriver is useful so many screws. Thanks for making and posting the video.
Glad it helped you out. This one still has a lot of screws but my P115 has a lot more lol.
Wow. I'm scared of Yamaha. Too many keybed issues.
They have been rock solid for me! Keep in mind we use these pianos for a piano bar situation and they are played 8-12 hours a day, 365 days a year. I do this repair about once every 6 months of use so that's a ton of playing hours!
Excellent vid and excellent work. 10:16 hehehe ----- we know the feeling!! I better order some spare pads while I can too. It looks like we need pads combination 11, 12, 12, 12, 12, 12, 12, 5. Making up the 88.
Question for you....hope you can help me out.... i own a white 515... but the panel just above the keys with the logo on it, has become smutty due to the dust cover...black stains... I want to exchange that....after taken the side panels of, I can lift it out? Or still attached with screws?
That is kind of horrifying that with this few hours it needed repair. That said, the environment plays a big factor. Often it is not the playing, but the "crap" that manages to find its way under the contact pads that causes issues - spilled beer, dust, hair, food, etc. Anyway, nice job!
Its crazy how similar the inside of this keyboard looks to my 1996 Yamaha P200, and P150
Yea we put tons of hours on our keyboards. 7 days a week 8-12 hrs a day. But yes lots of crud gets in there. I am fixing 2 of them now.
Purchasing a brand new P515 and if you were playing 3 hrs per day, how long would the instrument run well for before you started encountering problems?
Ours typically gets played eight hours per day and I would say around six months.
Sounds like by now, you've been inside that 515 a few times. Here's something I've run into and is still unresolved. Have you experienced anything like this? Just did my first repair on a P515 almost identical to your repair. Because I didn't have much history on this piano, I went ahead and replaced all the contact strips. All went smoothly....almost. At the same point you interuppted reassembly to test it, so did I. The keys that I replaced the contacts on all work perfectly. That said, the bass clef is silent. Starting with A below middle C, it plays 8 notes with a constant sustain until I cycle power. From there to the bass end is silent. The demo songs play perfectly, so I assume the problem must be in the kb module. I opened it back up completely and found the rubber strips "slightly off" which seemed minimal, but just in case, I got them perfectly aligned before reassembly. Next I inspected the ribbon connectors under a "scope" and found one wire that wasn't seated correctly in the connector. I fixed that and hooked up the electronics panel and powered it up. Same issue. Removed top panel again and double checked the ribbon connectors. I couldn't see anything so broke out the meter and tested continuity from beyond each pin (of each ribbon connector) from one board to the other (from the center board to the bass end) and they're all perfect. Its almost as if the keyboard was split and the left side was turned off.........meaning it might be a software issue......but again, this is the first 515 I've ever seen. So anyway, have you ever experienced anything like this? Any thoughts? Thanks. Jim
No I’ve never had that happen before. Strange though. Let me know if you get it figured out.
I just bought one of these used for pretty cheap because one of the keys was jammed and wouldn't make a sound. Thanks to your video I was able to take it apart and found a guitar pick jammed under a key. It came out and it all works perfectly. Thanks!
Oh my god that’s amazing! So glad it helped and hopefully things like this will allow me to grow the channel.
Awesome Help. Much appreciate Sir!! My side panels are cracked, and I didn’t know it was that easy to replace!!!
Question: To simply replace a key, would I just need to access the top of the keys as shown in min 7:39? That’s before taking off the speakers.
I believe that is correct.
Thank you @@latenightdiy1496
Would you recommend buying a Nord over a Yamaha P-515?
I don’t really know much about Nord but I know a lot of pros use them. I love the sound of the 515 but I feel like if you’re spending a lot more money on a Nord you’re probably getting a lot more features. For piano bar we don’t need all the sounds and features. We just need a good Piano sound.
In my brand new P515 three near located keys near right end (but not in the end) sounds mush shorted time even if I use the pedal.
Is this anything I can do /exchange, or its common case ? Thank you.
Hmm Im actually not sure about that one. I would say send it back if its under warranty.
@@latenightdiy1496 Returned P515. End up with Kawai ES920, could not be happier .
My guess Yamaha's long time production keyboards returned , then going to some Dealers shops and after repairs sanding back to stores. My packing Yamaha cartons was in really bad shape, looks like they traveled a lot...
It baffles me they use such primitive technology, unless it's done on purpose to break
Is this the same fix for broken keys that are stuck at maximum fortissimo?
I believe we had a low D that did exactly that and it was because of a torn rubber contact. You basically need to open it up and look very closely at that rubber button.
@@latenightdiy1496 Thanks! The music store wanted to charge me $400 to fix it, but I think I'm gonna try to do it myself, first;)
@@peter5.056 Yeah it’s not too difficult but the most tricky thing is making sure to stand the action up when you’re trying to replace those little circuit boards because if there’s any weight on the keys it’ll make it difficult to put those button strips and circuit boards back in. Good luck!
@@latenightdiy1496 ty!
Hi thanks for the video, do you know where I can Buy these (I live in Europe)?
If you’re talking about the whole piano I’m pretty sure you could find one on eBay. If it’s just the rubber key strips I usually have to order them directly from Yamaha.
@@latenightdiy1496 Thanks, I talk about rubber strips of course, sadly Yamaha's web site doesn't have any spare parts category... 😢
@@thomasquemar969 Oh yes the website is www.yamaha24x7.com you have to start a consumer account under the main menu.
@@latenightdiy1496 This web site is for US customers only but I found another one which sends guenine parts to europe, "syntaur". The price of a 12-note rubber strip is about $15, is this relevant?
@@thomasquemar969 oh glad you found a source. That’s actually really funny because that exact company is 1.1 miles from my house. 😂
