Turned on my LG 65UF6800 one day and all I got was the right half black and the other half was a random color that would change every couple minutes. No sound, no menus, nothing. Tried resetting, nothing. If the problem is a board, I’d love to know which one before I have to go through them all one by one.
@slicergba going strictly by your description, this sounds like a bad t-con board. Post some images of what your screen shows with your question. Use this guide Adding images to an existing question for that. That way we can see what you see.
