I can probably help. Are you sure it is a MarkII, nota MarkIIXG? Is the model of your original control unit DKC100R or DKC500**?

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
