Looking for a "map" of the CVP 85-A circuits

[leonardm]

Hello,
I'm looking for the technical "map" of the Clavinova CVP 85-A (circuits, chips, cables, ...).
No one can repair it at Yamaha Music France because Yamaha does not produce CVP 85-A motherboards any more. I decided to do it by my self and I need this "map".
Please help !
Regards,
Léonard

See if you can order the service manual from Yamaha. I don't know how to do that in France, but in the US you can call customer service and order the manual. It gives you all the details down to every chip and resistor.
