This video was so helpful! I have a P-85 but this is close enough. Had a bunch of high keys that would randomly trigger themselves, and soon after that the rest of the keys would fail to play on every few hits. Trying to get into the thing was pretty daunting. Your video gave me all the information I needed. In my case, it was the PCB for the highest set of keys that was the issue. It had corrosion from a spill. The design of this keyboard kept the liquid neatly contained in just that one area. I got a replacement for that PCB and for its ribbon cable. Worked like a charm. I think the reason the other keys were behaving strangely was that the self-firing high keys were spamming the polyphony. I did have to wait a couple months for the part, but you can imagine how pleased I am that I was able to repair a $700 machine with $30 in parts and shipping. Thanks!

Fantastic to hear it helped, mate! Thanks for letting me know.

Agree with you regarding the great Yamaha documentation . And nice to see how a keyboard is done too . I've said no to a couple of keyboard repair offers lately , and having seen this I'm glad I did . Apart from having no expertise , I knew that the bench space and storage would be a problem . Cheers .

Enjoyable to watch even just for entertainment... you're a nice, decent bloke Brad. Great videos.❤🎉

My perfect new P95 Thank you so much for this pair of videos. This week bought a P-95. It was in pretty good shape, but one key was intermittent. (A black key, so not one I would use very much ;-) Based on your videos, I took it apart, inspected it, cleaned it very thoroughly, reassembled it (no missing/leftover pieces!) and it works like a champ. A few comments: 1) I don't know if you mentioned it, but the silicone "sensor strips" are not symmetrical. They look like they are, and they fit either way, but there is a definite upper and lower row. (The difference is the height of the carbon pill inside the dome.) On the top side, for correct orientation, there is a tiny arrow/triangle which is visible in your video. 2) When I went to replace the long screws down between the hammers, I wan't able to see any trace at all of which holes had been used before. I decided to just sort of wing it, spacing them out and being sure that each chunk of keys had one screw, As it turned out, the "wrong" holes didn't have any threads in them: the screw just dropped to the bottom without engaging anything. 3) When re-inserting those ribbon cables into the connectors, I found it helpful to orient things so I could look into the connector. If you don't see where the ribbon cable or wires are supposed to go, it's easy to get it wrong and possibly bend things. They are so flimsy that there is not much margin for error. 4) The bits of fiber tape in my keyboard had no adhesion left. So I just used what I had: plain old Scotch tape. It might be a good idea to plan ahead and have a more appropriate kind of tape ready. 5) My keyboard was a *lot* cleaner than the one you worked on. Yes, there were dust bunnies, cat hair, and (you said it!) glitter, but no sticky accumulation likely to cause corrosion. (I live in a dry climate, so that helps.) 6) The most difficult part of the cleaning process is that there isn't any great way to remove silicone grease. And (for a meticulous cleaning, anyways) it does need to be removed: that's where all the dust and grit accumulates. I basically scooped away globs with a wooden coffee stirrer, and then wiped away as much as I could with paper towels (the tough, public-restroom kind, not the fluffy ones for home.) I removed all of the hammers (keeping them in order!) in order to get at all of the sliding surfaces. For reassembly, I used a wooden coffee stirrer to apply (just enough!) silicone grease. Thanks again for your excellent pair of videos. Not only did they encourage me to take this leap (buying an older used electric piano) but they saved me from mishaps and disaster on several occasions.

A question: I recently was given a P-105 which only has four keys working per octave (2 white, 2 adjacent black)--they're the same keys on each octave. Is this something that replacing all the individual PCBs could solve, or is something bigger going on? Thanks for any advice you might have

@BradsGuitarGarage

The boards share connections, meeting at the central common board (in these units there are 3 from memory). If the damage is to the central board, there's a chance that it's hit the bus downstream of the other two boards, so it would share issues across all 3 boards, despite the damage perhaps only being limited to the central one. It's often preferable to replace all 3 (they are relatively inexpensive) unless you can confirm for certain that the damage is limited to only one.

Rush fees are normal. You're asking them to do overtime, essentially. They can't put back all the other jobs to fit yours in and be unfair to the other customers, so they need to fulfill the dates they've committed to with the previous clients. And to do that, they need to stay back to do more hours, and of course they need overtime rates to do that.

I guess the only downside to installing internally is that if you find an issue and need to perform a firmware update, you would need to make a cutout to access the USB-C port.

My p-35 while playing it randomly stops sounding all the notes and by pressing the keys, the functions are activated. much like when pressing the function mode. The function button is working properly cause i checked the continuity with the multimeter. then if i turn it off and on will sometimes have a red blinking red light sometimes it will work, but then it does it again :( i don't know what to do, all the components seem fine upon a visual inspection and it is all very clean and corrosion free

Get in touch with Yamaha if you're not in Sydney, mate. They'll let you know who the nearest service tech is.

Sidebar: TV/stereo remote controls use the same type of carbon-conductve circuit-board pads and buttons; schmutz and schmoo often work it's way between the buttons and board, causing intermittent operation. They sometimes clean up okay with just alcohol and a q-tip, but remote controls are often far, far filthier internally than this Yamaha keyboard, and I've sometimes had to scrub everything with soap and water and a toorhbrush, followed by alcohol, and perhaps cleaning the buttons and pads with a pencil eraser. Only worth doing if a new replacement remote, or programmable universal remote that works for a particular model, isn't available. Glad the service manual for this Yamaha keyboard is so detailed....but I can tell you from experience that the service manuals for a Yamaha surround sound receiver are terrible. They typically run well over 100 pages; the old style paper manuals have giant fold-out schematics, but on the more modern stuff they're only available in computerized form, which means that when you electronically enlarge/magnify the schematics they become so grainy and blurry that you can't read them, no matter how high-resolution your monitor.

Look carefully for broken solder joints around the output jack area. If all is well there, trace the signal back to where it stops with an oscilloscope and that will lead you closer to the cause.

I've done that before and they always come back in a year or two. Once the corrosion has started under the solder mask, it doesn't stop. Boards are cheap and take less time to replace than to repair.

Next time, clean the dust off the key contact boards before removing the rubber contacts, it helps to avoid contaminating the contacts on the board. After you do that and remove the rubber contacts,then you do a second vaccum.

Sorry mate, can't find my crystal ball. I suggest you take it to a local reputable tech.

Wow ---- I didn't know that they use those tv remote control type tactile sensors for these music instruments. I know that the tv remote control ones can be trouble after a while. Rubber boots also probably break down with age. Will be interesting to find out later whether all digital pianos have this same sort of sensor style. The staple inside the keyboard was a bit ridiculous haha. And the amount of dirt build up was indeed quite disgusting. One comment about the servicing of this unit --- is --- that I have seen different levels of care among different 'techs'. I admire the ones that don't have the instrument scratched up (or has scratches) when it is returned to the customer after the servicing is done. So if I were to flip the keyboard upside down, where key surfaces, and top panel surfaces are going to touch the bench --- then I would prefer to have those surfaces rest on a clean and soft surface. This is so that grit on bench or abrasive surfaces don't introduce nicks and scratches to keys and panel surfaces. Also later taking into account of sand/dirt coming out of the keyboard can contaminate bench top surfaces -- so that needs to be considered even if a soft surface is used. Also - when you accidentally allowed the detached key-bed to fall away from the outer cover - where the keyboard impacted the bench ---- that was a brow-raising moment. Should totally be avoided. Otherwise - very nice servicing session.
