Problem with digital piano Kawai CA 17 key.

Sometimes not very often this key goes up, but the note remains sounding, as if the key is still pressed. Don't you know why does it happen like this? May be, this problem will disappear with time?

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

have you tried using the can of air. you can get it at almost any drug store walmart or kmart. just spray the can of air between the keys and they should become unstuck.

SOURCE: It's a Roland HP-7e digital piano about three years old.

You may need to clean the contacts which are usually conductive rubber. I explained stuff for another Roland problem with two keys that were intermittent. I have an EP-7 that I had to do the cleaning of the key contacts. Use 91 or 99 % Isoprophyl alcohol to clean BOTH the conductive "pill" (Black under silicone rubber domes) AND the traces on the board where they press. Clean gently as the traces have a hard black coating.

White spirit is NOT what you should use. Mineral spirit leaves a residue film.

Use 99% isoprophyl alcohol.

ALSO inspect the contactboard for cracks by candeling with bright light behind it.

Check if it might be dragging on the edge of the case. The restoring force for some of these comes from a silicone rubber dome that is oart of the contact. SOMETIMES the dome fails.

Why do keys produce no sound?


Hi Kyle:
Have a look at your manual.
Sometimes you'll find that there will be an "input" setting required.
You might also try google with his link.

QS8 keyboard. Why is volume in organ mode much louder than piano mode when I switch between modes without touching volume slide?


On organ mode, in general, almost all brands of the modern keyboard, velocity setting is not enabled. Setting velocity is used to determine how much the level of the sound that follows how strongly you press the keys. It is really just to imitate the sound of vintage organs, which in the past, electronic organ technologi not use the velocity on the keys. So, how strong / slow we press the keys, the sound level will remain the same.
At the Piano mode,modern keyboard using setting velocity. This also to imitate an acoustic piano, which, if we press the keys slowly, the sound level will be slow as well, and vice versa.
So, in your case,at the same volume slider, try to play on the organ modes, note level. Moving to the piano mode and press the keys securely powered (full power). Then the sound level should be equal to the organ mode.
On modern keyboards, also included organ sound that added velocity setting. Usually found on the user bank.

What is the piano age by serial number 1872


Hello, you will need to look inside the Factory's site. Generally, they put a link to this purpose. If not possible, try a search section in Google, using words like: "serial number" age piano Kawai, changing the Kawai word for the name of the maker of your instrument.
Good luck!

I just experienced my p85 with a key problem on the F# below middle C. You will need to disassemble the keyboard and usually the keys are groups of 6 - 8 keys. If you remove the group that has the problem you might be able to find the problem visually. Mine just involved removing and reinserting the F# key back into the assembly. Then reinstalling the group of keys. If you can't get the key to work properly, you will probably need to buy the group assembly from Yamaha.

Hi there, I have a Nord Stage EX 76 and played a gig on friday night outdoors. I have set the keyboard up and now one or two of the notes occasionally sound much louder than they should. The problem...


What has happened is that one of the contacts on those notes is not working properly. Each key has two contacts. One makes before the other as the key is pressed. The processor MEASURES the time between those as you hit the key to read the VELOCITY you have hit the key with. This velocity is often used for loudness on many voices such as the piano. These contacts are USUALLY conductive rubber pills suspended in silicone rubber "domes". One can disassemble the key area and clean BOTH the black rubber pills and the circuit traces they are pressed against using Q Tips and ONLY 99% isoprophyl alcohol to restore proper operation
One needs to be very careful when disassembling unit as there are many tender ribbon cables and connectors. Best to have clear work area and two people to "control" the halves of the shell while opening..
