This TV did have a burned out (blackened, actually) LED on one of the backlight strips. I replaced that whole strip, and all the backlights are now working/steady, with no blinking… unfortunately, there is no longer any picture on the screen. Before, when the backlights would flash on, I could see the LG menu and screen, but now there’s nothing, just a dark-gray screen.
ctgriffi first thing that comes to my mind is to recheck all the cables and connections. IF your backlight works etc. then check the main board and the T-con board (let us know the exact model so we can check deeper). check to make sure that you have power to the T-con board.
