Options. 28-06-2020 07:00 PM in. I got a trouble with my Samsung UE55KU6450 Smart TV (4 years old): When I turn on TV, screen works fine in the begining, but vertical shadow stripe appears a few later. I note the same area at the rear of the TV is a little hot, as the bottom front. I've tried auto image testing and trouble remains in all tests.
Chosen Solution. One of the common failures is of the LED strips inside the TV which provide the back light. It can be a single LED that fails since they are connected in series. i have successfully changed the individual LEDs to repair these recently. If you have a volt meter, check the voltages present on the connector that goes to the panel. hbsGWsE.
