Hello,
I bought a damaged PX-780. It seems that the controller is dead (it powers up but the screen is blank).
I have an AP-260 main board. It is the same PCB (M290-MDA1) with somewhat different connector setup.
I need circuit diagrams (service manuals) for both models so that I can replace the PX-780 board with the AP-260 board.
I'd appreciate any help with these schematics.
Janos
