My TV is randomly doing the thing shown in the above pictures. It shows up at random and stays on for anywhere from a few seconds to a few minutes. And as can be seen in the second picture, it shows up even over top the popup menu at the bottom of the screen.
I contacted LG since my TV is still under warranty, and they gave me the name and phone # of a local repair shop to contact directly. They came out and replaced the main board but as can be seen in the above pics taken earlier this evening, the problem stiil exists.
It is an LG 50UH5530 if that makes any difference
I'll be contacting LG/repair company again but was wondering if anyone knew what the problem likely is?
