My Yamaha Clavinova cvp-7 will turn on but the keys wont play?

The pedals have long since stopped working and now the keys, but this was passed down to my daughter, a budding pianist. I would love to be able to fix it if possible. Any suggestions?

SOURCE: My Clavinova CVP 305 Piano will no longer play the

The EPROM IC might be defective and might need a change but with the help of the Yamaha service.
Howeverr leave the set ON ffor several hours if you have not used or sparingly used.Sometimes moisture within the set can cause these issues which ccan clear up when the capacitors charge up or the board warms up.The interface is having some errors /conflicts that cause this conectivity.
So keep playing , do not switch off .
Hope this tip helps.

SOURCE: Can I replace the pedal unit to the Yamaha Clavinova CVP-75?

I can't solve the problem, but just wanted to sympathize because I have the same problem. My pedal is broken on my Yamaha Clavinova cvp85a. It worked wonderfully for years but finally it broke.
I'd be in the market for buying a new pedal or fixing the old one. But I've not found any suggestions in any of these forums for either solution.

Hi, I hope can help me with this problem because I start to get desperate. I have a Clavinova CVP-85A. The sustain effect is always activated, whether the pedals are plugged in or not. I read that to...


It sounds like the inputs from the pedal switches are "floating", that is, not pulled up or down and they are drifting across the logic threshold. If I could find a schematic I could direct you right to the problem. For now, check the voltage across the switch contacts with a high impedance meter. Also check the resistance to ground of the common of the contacts. Without a schematic I am afraid to have you try things lest I direct you to do something that would cause damage.

The disk drive on my Yamaha Clavinova CVP-105 acts like it has a disk in it when it doesn't and won't always play pre-formated disks like it used to. Is the drive dieing? Where can I go to get it fixed? ...


Often these drives are continuosly selected by the controller and rotate even without a disk.

These USUALLY use the old 720K disks which are almost impossible to find. The common 3.5 1.44Mb floppies often will not work in these units.

You can SOMETIMES use the 1.44Mb disks by covering the second corner hole AND degaussing the disk with a tape eraser and then reformating the disk in the Clavinova.

The pre-formatted 1.44Mb disks without degaussing SOMETIMES leaves artifacts between the tracks used by the 720K disks that causes problems.
