Hi
If you are talking about cleaning the rubber contacts I wouldn't bother. Once they start to fail then it is best to replace them. You can do this either for the octave giving problems or best to replace complete set. Main part is VY84670R your piano has 6 octaves of these. with a shorter part at either end.

Either the keyboard is disconnected or the Keyscan on the keyboard itself is but. More than likely a loose connector.

How can I repair dead keys of Yamaha ypt310


It depends on the type of problem. If you have dirty contacts, then they can be cleaned with contact cleaner. If the keyboard has had water damage, then the key contacts could be badly pitted/rusted, in which case the keyboard would have to be replaced.

P90 sustain sound won't stop some times when am playing


You could have-
dirty contacts on the switch inside the pedal
dirty contacts in the jack the pedal cable plugs into
a cold/loose solder joint where the cable connects to the plug or to the switch.
If you rule those all out it's an internal problem with the pedal, which you can check by using another pedal, or it's internal to the P90, which will need to go to the shop.

Check and see if there is a switch on the foot pedal. Check the P-90 menu under footswitch to make sure it is set to sustain.

Yamaha keys g and c# don't work


You didn't describe your problem with enough details. If the keys operate mechanically, then the problem might be with the integrated switch assembly. You will need to disassemble the entire case enclosure to check the key assemblies. The keys are assembled into sets. You can remove the set with the bad switches and replace the entire group. In some Yamaha models you can replace individual switches ( entire key mechanism). You can also test the switches using a multimeter - simple continuity test.
If your keys are inoperable mechanically, ( won't move or move partially) you will have to disassemble the entire unit to identfy the problem. It may be a simple alignment adjustment or a broken pivot joint. You won't know for sure without removing the internals by taking it apart.
Yamaha has excellent service reps (factory trained) either in repair depots or available for house calls. Go to their web site enter your zip code to find the nearest rep. If you are not comfortable taking the keyboard apart, that is the best solution.

Dead keys yamaha psr e413 keyboard


Dead keys on Yamaha PSR e413 keyboard: Flip keyboard upside down, remove cover screws (use marked cardboard template to remember where they came out), spray suspect key-contacts with fast-drying contact cleaner, (usually a PCB with a matrix of contacts under keys), re-assemble base cover, wiggle faulty keys as far as possible to 'scrub' any dirt or oxidization. If this cleaning trick doesn't work, get a pro to check it.

Hello, I have a Yamaha P90. 4 keys are not responding. all others are ok and give sound. What happened ?


If they are the same note- different octave- it may be a bad solder joint near the main oscillator IC.

If they are the same cluster (adjacent white keys or adjacent black keys) in the octave, it may be a faulty wire connection.
