Doug, This is what I thought. I used a can of freeze spray, tap the board all over and could not get the left channel back. I want point I did if I selected Dolby for the output, but the audio on both channels was a lot lower than it should be. When I got out of Dolby and went back in, no left channel again. Like I said, this thing is hard to trouble shoot with everything connected, when there are no markings on the bottom.

Does freeze/heat make any difference? Sounds like a bad/intermittent solder joint somewhere.
