pioneer qx 8000

Left channel has quit playing all of a sudden. It just started buzzing even though there was no music playing, I just happen to be in the room when it started. Speakers all work on a different amp and the output drives all meter the same. Anybody worked with this issue?

Re: pioneer qx 8000

Could be a bad capacitor in any amplifier section. Possibly a poor ground connection. Power supply problem would be unlikely as the other channel is working. Is the problem evident in all modes (tuner, phono, aux)?
