This unit came in after a big electrical storm. When power is applied you hear a slight hum from the speaker outputs but it does not respond to any input. It seems to be a problem in the output or driver section but this is difficult to trace. Does anyone have a service manual for this? Thanks, Lenny

Probability-wise in those circumstances, whatever can least accommodate
voltage surges, so anything requiring a nice low 3.3 or 5V supply ie the
main system control micro knocked out first
