Phil,
Don't go through the same thing I went through.
I had a customer with a high end receiver, I repaired the original
problem..came back twice for solder
connections in different circuits..
Examine the board carefully, especially anything standing off the PC. Move some
of the larger transistors
while looking on the bottom of the PCB to see if the leads are moving also.

Pioneer SX-303R stereo reciever.
Tried to keep subject line brief.
Customer complaint was "it lights up, but with no sound thru the
speakers. just a low hum in speakers is all thats heard".
I powered it up on bench, and works fine. Unit uses four power
transistors as outputs, not the STK modules. All seems OK, tho.
Is he possibly dealing with protect mode due to some bad speakers in his
home?
