Audio, video, tuning, OSD, switching functions are apparently normal except
video mutes after about 1 sec.  Suspect micro may not be getting sync return
and thinking it should mute video, but I have no manual on this one.

Same symptom on tuner and video input.

Does anyone have a manual?  Anyone see this problem before or familiar with
the circuit that does the muting?
