Magnavox Plasma TV Model # 50mf 231/37
Power up problem: On pwr up the pwr lgt comes on, hear relays click - no audio or picture. Pwr lgt stays on.
Unplug and replug unit until audio and picture comes on - works normally from there, ususlly takes about six tries.
Occasionally the audio will come on without the picture. On occasion the picture will fill the screen and disappear again. Maybe relay points not making contact???
