It sounds like it could be a row of dead/stuck pixels....Does it happen to happen on all sources? On a game system DVD player etc?
I have a Samsung 50" plasma TV and it's over 3 years old. It has a thin read line on the screen and I'm wondering if this can be repaired and how much would my repair cost. The line is quite noticeble when watching sports on grass fields or anything with a green background. Help.
