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? Leonard G.
