Subject: [disklavier] DC3FII Stopped Working -- Need Service Manual
 
  
I am a new member.
 
Our DC3FII (with DKC850 controller) stopped working between songs.  I suspect the problem is the power supply mounted under the piano, as I no longer hear the high-pitched sound it used to make.  I am an electrical engineer,  but won't be able to make much debugging progress unless I can get a service manual with schematics.  Are they available?
 
If I can't repair the power supply does Yamaha repair them or sell new ones?
 
I appreciate any advice, also perhaps on tests that can be done to help identify the problem.
 
Thanks
