SOURCE: yamaha clavinova clp 200 - ear phone jack slid

The control panel hinges upwards and you have to move the keybed back a bit to get at the jack. All the screws on the bottom for the keybed. I'm not sure where the ones for the control panel are.

Without power to the unit no sound should be generated. Make sure there are no other connections.

MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.

Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.

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.

How do I remove the top cover of a Yamaha Clavinova, CVP 30 digital piano?


There are 2 possible things to look for - can't remember due to age of your instrument.

Look under the piano - about 20cm in from front corners, can you see a screw head set in a metal bracket. If so undo these and the top cover / lid will lift.

If not try : Close cover over keys, get a torch and look above the cover through the slit to the far left and right about 10cm in you might see a screw head - under these (1L 1R ) lift top cover / lid.

I hope this helps

HOW TO REPLACE CONTACT STRIP OF YAMAHA CLAVINOVA CVP 92 DIGITAL PIANO ?


Successful repair of my Yamaha Clavinova CLP 880

The principal to replace your contact strip will require one further step to that shown here where the customer has replaced the felts.

When you have the keybed out you will see the contact strip part 220. This is held in place behind the circuit boards. Remove boards, replace strip and reassemble.

It might be worth considering felts whilst you have the keyboard in bits as these wear out.

It sounds like you have a part overheating and failing, then cooling off and starting again. i would take it into the nearest Yamaha repair facility or contact your local authorized repair to come take a look before it goes out of warranty.

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.
