Per advice yesterday, we took the back off an tapped on the circuit board to find a loose connection, etc. Everything looked fine. TV stayed on for about 1 1/2 hours or so. The SECOND I went to move the circuit board the TV shut off, requiring us to unplug it, wait 15 minutes or so, and plug it back up...dont see any dark areas on the board and have wiggled all cables and cannot recreate the problem in a specific area..any suggestions?
