Disklavier

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.
