No Sound Yamaha Clavinova CVP 96
by: Alfred

Dear Joey: I believe the CVP 96 is a stand-up unit, and energized by a cord directly from the outlet? The problem COULD be 1) Defective Component in the iunternal circuitry, 2) If you used light-weight Headphones recently, did you remember to remove the Adaptor? 3) Try Initializing the keyboard by pressing the last white key WHILE turning the Unit ON. (Warning any previously recorded music will be erased). You should not attempt any DIY action other than (2 & 3), and have a qualified technician check the instrument if these do not resolve your problem. Good luck, and please keep us posted so we can all learn how you fared. Thanks.

CVP-96 AUDIO PROBLEMS
by: MARK J SCHACKNOW

I have a CVP-96 that had no sound on the left channel and white noise on the right channel. The problem ended up being (IC1)on the jacks/eq board, an 8 pin surface mount dual op-amp IC for the line input channels. Since I am a senior technician, I traced the problem down with my scope to find that the IC (UPC4570 or NTE 778SM) was in parallel with the L and R channels from the digital board. Removing the IC from the board solved my problem. (I CAN INSTALL THE IC LATER IF I WANT TO USE THE LINE INPUT JACKS.) This isn't a job for something that came from Radio Shack. Be careful and good luck. I also have the schematic on this model if anyone needs help. tubeman1@windstream.net
