Yamaha CLP-860 Digital Piano Keys Making Noises

As the elecrical power off, the keys are making clicking noises as they release from the down position. This becomes a nuissance clicking sound when I play staccato notes at lower volume setting. Is this common on Yamaha digital piano? I would think the felt at the top and botom stopper need to be replaced. I would believe that those felt would be easy to replace. Where can I find he information on how to replace the felt, what part number, and where I can purchase those parts.

Thanks

The part numbers are only available through the Yamaha Corporation. The Service manual, which is available for purchse (note that this is NOT the owner's manual) will have them.

I repaired mine on my own. I used a sticky foam tape of the correct width (approxiately 3/8 wide) and overlaid one layer directly over the original felt pad. I used a white foam tape like is used for carpet or other indoor needs. If I were doing it again I would probably use something just a little thicker and softer than what I used (appx. 1/16 thick).

Disassembling the Clavinova and removing the entire GH88 keyboard for this work is not hard if you are even moderately handy. I had the entire mechanics of the unit laid bare in 45 minutes with no manual (and not one curse word).

I am going to write up a tutorial on this soon as many people have asked about it.

By th way, I have heard that the factory pads are $100. My solution cost me about $3. Even if I have to do it again in a year, it's a win.

    DinoBob -

    I have the YPG-625 model from Yamaha. The keys make a 'clunk' noise when released, which is quite annoying while playing softer passages.

    I'm unable (and unwilling) to pay exorbitant fees to get this problem resolved. However, I need to know exactly how to disassemble the keyboard without removing any unnecessary screws.

    Also, I notice that even keys I never use (at the extreme ends of the keyboard) make the same clunking noise. It seems to me that they'd be quiet, since the felt padding wouldn't be worn like it would be with keys that are used often. What gives here?

    Any advice you could give would be much appreciated. Thanks!

    Hello DinoBob!
    I think I have the same problem as the Paul guy with his YPG-625. I just bought a CLP840, and clickity clunk on every single key. SO annoying. I feel like I bought a lemon.
    Did you make that tutorial on how to put the tape in? I would love any advice you have.

    I did the same on mine Clavinova CLP-810s using the felt tape commonlly used for isolating windows and doors. Its is fairly simple procedure.

Try dusting the keyboard with talcum powder. Shake the unit around a bit, so it gets under the keys. That will likely help "lubricate" the keys and quiet down the noise.

Yamaha digital piano clp 170


This is a common problem with Yamaha keyboards. The problem is caused by worn-out rubber contacts in the keyboard assembly. In my old Clavinova CLP-500, there was one long rubber contact strip under the keys with two parallel strips of semiconductor material. The Clavinova circuitry determines key velocity by measuring the timing between when the key hits the first and second strips of semiconductor material. The harder you play a key, the less time it takes the key to hit the second semiconductor strip after hitting the first.
After years of playing the keyboard, the keys eventually cause tears in the semiconductor material and this messes up the timing measurement for key velocity. The only solution is to take the keyboard apart and replace the rubber contact strip with a new one.
I got rid of my CLP-500 four or five years ago and got a new CLP-170. The CLP-170 is now having exactly the same problem that the CLP-500 had. Yamaha has re-designed the rubber contacts in the CLP-170 so that there are now eight individual contact strips instead of one long one. The problem is essentially the same, though. You have to take the keyboard apart and replace the worn out rubber contacts.
Here are the part numbers for the rubber contacts that need to be replaced in the CLP-170: V8286600 Rubber Contact, 12 keys, D-C#   Qty. 6 V8286800 Rubber Contact, 11 keys, A-C#   Qty. 1 V8286700 Rubber Contact, 5 keys, D-C   Qty. 1
I suggest you also get a copy of the CLP-170 service manual, part number 001677. It has descriptions of all the steps necessary to take the thing apart and put it back together again. You'll also need a "rod" (which is just a long dowel), part number TX000670. Before you take the circuit boards off the keyboard assembly, you have to insert the dowel between the keys and the frame to keep the keys from falling back and getting in your way. A 5-foot long 1/4-inch dowel will probably work. (I haven't yet taken apart my CLP-170, and I don't have Yamaha's "rod," so I'm not sure if 1/4 inch is the right size or not. I'll report back here if it's not.)
Good luck, Howard
