I have a C-35 Concert Piano. The power comes on, the speakers pop, the lights light but there is no sound. No output from stereo outs and no output from phones. Help anybody?
I have found bad surface mount capacitors that leak and eat the circuit board area around them. I have been able to replace all the small surface mount caps and make these boards live again.

Kit Kelly, I am a tech in southern Florida and I have come across several of these pianos with this problem. The problem is in the mixer/preamp board, No longer available from factory. I have been able to find the bad parts and bypass them, but it only buys the owner a few more month. Technical answer, Check IC 12, Q1, Q2 or the capacitors around IC 12 on the mixer/preamp board ( KLM-1546) the board with the MIDI outputs on it. I find the last good signal area and connect it to the first good area of the preamp area going to amplifier. I personally owned one of these and just last year I had to put it down :-(
