UN55MU8000 Black Screen With Color Vertical Lines

JUMP TO SOLUTION

I have a MU8000 series TV purchased in Dec 2017. Just today, after working perfectly for 20 months - and we were very happy - then just this evening the screen went black on all inputs (Roku and DTV are separate inputs). On the black screen are colored vertical lines (mostly purple and green) which shift and grow/shrink on the screen. Can still get sound perfectly on all inputs and can change channels on DTV. I have tried to reboot the TV, Roku and DTV boxes together and individually (didn’t work) and unplugged/replugged all cables (also didn’t work) including the DTV and Roku cables and that made no change. Attached is a picture of the screen. Seems like other models have had similar but maybe not exactly the same problem. This would be crazy to have to buy another TV after 20 months of use. I need a solution to try that is not super expensive!92863E26-0452-4DBF-85AB-FA082C2F58D0.jpeg
