Worked fine until one day I was playing electric cello thru it. Sound stopped. NO longer produces sound in any speaker output, but still does in head phone output but only in one channel (left). discovered speakers I thought were 8 ohm really are 4 ohm, but had been using them for 2 years. cooling fan also is not coming on but I don't know if it should be on whenever receiver is on. Fuses on power/big transformer board see OK, can't find another fuse but haven't fully disassembled it to look. Front end still lights up, the thing looks like it is functioning normally as far as panel lites and changes with switch changes but no sound. Turning off and on is no help.
Most of these problems are rooted in a failed power amp module.
I'm working on an older technics unit but with the same troubles.

Similar problem here, but powering down for 15 minutes gives me 10 minutes of audio, then goes off again. Sub is still working, can tell if I turn it up full blast. By the way, the fan is designed not to turn on until there is a fire, then it turns on and fans the fire....(technics only)
