Tv Lg 42lv3500 no se ve imagen , lo único que se ve son líneas de color verticales y luego van desapareciendo hasta quedar en negro , me podrían ayudar por favor

No one ever shows how to get the wire adapters off the ends of the LED strips! Also, the spacers are very brittle, if you put a 5 in one under it, it will break. Take them off from behind and just push it in a little where the catch is and slide it gently on the face side.

My Tv is blank (not showing picture but has a black light display instead of pictures) but still plays sound loud and clear. What could be the problem please? “LG 43" smart. Model 43uk6400plf. Firmware 5.50.15”

Mine has the similar situation, no picture shown most the time and whenever picture is on, left half of the screen is flickering with white stripes (on and off) , I thought it might be the display controller's problem but not sure, will someone could guide a direction on how to fix it?
