If no one has a schematic diagram, and the amp does nothing when you power it up, you should begin checking the DC voltage on the pins of IC1 on the power supply driver board.

You should have ~12v on pins 8, 11 and 12.

You should have 5v on pin 14.

Pins 3 and 4 should be at or below ~3.3v.

Pin 7 should have 0v.

Place the black meter lead on the ground terminal of the amp for all of the measurements. Remote voltage will be applied for all of the tests above.
