My jittery blurry picture problem
Picture problem is slowly getting worse over the past week. First a thin horizontal black line appeared completely across screen, about third way down from top. Then a few days later a thin horizontal green line appeared completely across the screen about halfway down. Then the entire screen now goes back & forth from normal to slightly blurry & jittery, then back to normal. This is repetitive and takes only a few seconds each time.
Actually the blurry jittery portion is for only the lower half of the screen.
My LG tv model is the 60UH7700-UB.
Is this a good question?
