[TechAssist] Zenith SS6515G, Intermittent Sound

Friends,

This set has intermittent sound.  It's driving me crazy.  Once it comes
on, will be fine until turned off for awhile.  May come back fine, may be
no audio for several minutes, may no audio for hours.

This is all I know.  The audio pcb is fine.  When I have no audio, there
is no audio going into the module.  With no print, I don't know where it
is lost.  Thought it was the rear-panel switch that selects AUX
STEREO/TV, but that idea did not pan out.  Am pulling my hair out on this
one, but I have little left!

I know I am giving little information, but it's all I have.  Unit came in
dead.  I repaired the p/s and all seemed fine.  The customer came to pick
it up and asked to see it working.  It came on with no sound.  He said,
"Oh, yes, before it died it had no sound."  (Nice to tell me then!) 
While we were talking, the sound came on.  This has haunted me for three
weeks.

A schematic or even a block diagram would be most helpful.

All suggestions welcome.

Thanks,
