Hello.

I'm having several problems with my CVP-87A (Yamaha Clavinova), and I wonder if anyone can tell me where I can find parts list, schematics and/or service manual for this Clavinova model.

starstarstarstarstar 		CVP-85A similar to CVP-87A no sound
by: Neil

Unfortunately there is no link on this page to the service manual that I too would like. The fault on my CVP-85A is that the panel lights come on but no sound from the speakers or headphones. The Speaker Protection Relay is not getting the coil voltage. I have tested the relay and it does work on the bench. The power amplifier module has Vcc and -Vcc and I can detect an audio signal on a digital volt meter set to VAC. Plugging in a CD player and applying a DC voltage to the coil to operated the relay will play music. I have changed all the capacitors on the PU board, but this did not cure the problem.

Can anyone suggest a fix?
