Janos Posted February 25, 2021 Share Posted February 25, 2021 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.
