I have a question regarding my Samsung LCD tv. The model # is LN-T5265F. This started last week. When I first turn my TV on, I will have a very thin vertical green line on the left side of my screen. After about 10-15 minutes, it will go away and not come back until the TV is off long enough for it to cool off. Just yesterday it started putting 2 vertical lines right next to each other on the left side of the screen. Again, both lines go away when the TV warms up. What would cause this? If it was a LCD panel going bad, why does it fix itself after warming up? Any insight on this would be great. I know that if it is a panel going bad, it will exceed what the TV is worth. It has the line on all inputs also (PS3, Wii, and DVd) Thanks for any help.
