tv about one year old. never abused. left the room for ten minutes and returned to a tv with sound but no picture (black screen). changed cables, changed inputs, unplugged unit, etc, etc. when i used other inputs the input sucessfully changed with the remote as the audio matched the input i selected, i.e., cable tv, dvd, etc. i checked the fuses on the boards in back and all are good. no repair facilities within 150 miles. any ideas????
If you mean you've lost all picture, including the OSD and you've tried unplugging the set and turning it back and still nothing then I'd probably suspect either the Y or Z sustain boards.
