I Was Moving My LCD TV And I Touched The Screen, Now I Have Blue Streaks In The Screen. How Do I Fix It?
I have that too. But technicians tell me it is cracked glass and that I have to replace. I have also been told it would be cheaper to just buy new. I looked on ebay and found both replacement screen and instructions. But while I wait, I have noticed that some of the blue bits are going away. Maybe, if left alone, it will recover from this shock.
