Disklavier

Hi Peter.
Are you on Facebook, get in touch with Bill Brandom or Robert Charles Khumann they can give you the service manual for the particular model of Disklavier Control unit you have.  My best guess would be that it is a MK IIXG of some kind.  If you give either of them the DKC model number they should be able to give you the manual which has block and wiring diagrams and I think the circuits and specifications and parts for the whole system, very nice.
Hope that helps.
Cheers

I am new to the group, looking to purchase a used disklavier.
I would REALLY Like a U3 in polished mahogany, but seems most uprights are black.
Regardless, looked at a 1996 U1 disklavier today in Toronto, but the control system would not power.
It has been in storage for 10yrs, unwrapped and when we tried, both myself and the owner heard a click.
It would appear that there is NO Vcc on the system board up top, there is a transistor which may have failed, or maybe the aged electrolytic around it.

I can troubleshoot, but looking for a schematic to do this properly.

Piano is in very good condition, I expect this is a simple power supply failure but need information carefully determine for certain.
