After just disconnecting the internal cables, to lift up the PCB and see what is the digital filter type on the bottom side, the unit went dead.
All the stabilized voltages are there and correct but the display is dark and front panel buttons reaction does not occur.
On top - its my friends CDP that makes me feel more miserable :(
Please, help me with schematics to try and make it alive again :hot:
