Fixed Yamaha P85 no sound

by Dave

My P85 had no sound so I used the service manual to replace a part on the circuit board. C122 was at fault. The service manual has schematics and the pcb is well marked. I have an electronics background and know how to solder.

My Yamaha P85 had a no sound problem too. I replaced the two 100uf capacitors at locations C216 and C217 on the board where the DC power plug connects. Fixed it right up.
