I have Sharp LC-46XD1E and the TV plays fine but after 1 hour or so 2 1-pixel-wide vertical lines appear in the center of the TV (1 green 1 red) . I guess this implies that is not a LCD panel problem. I haven't opened the TV yet but I'm down to 3 possibilities :
1) flex connectors or cables from t-con to panel may be slightly off-place due to temperature
2)Image processor overheating?
3)LCD panel overheating?
What are your ideas in this ? Thanks for your answer.
