Chosen Solution
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. Update (05/04/2019) Actually the blurry jittery portion is for only the lower half of the screen. Update (05/04/2019) My LG tv model is the 60UH7700-UB.
I have repaired many of these under warranty. Unfortunately the problem was corrected with a new panel. The panel is as much as the TV it self. It is not a feasible repair. It may surprise you, as most of these models have or will come to an end, as in your case. Wish I could tell you different. Thank you for asking, Matt of Martins TV Repair.
