LG 65UH6030 Blue/white screen, sound but no picture.
I have a LG 65UH6030 - 65" LED Smart TV - 4K UltraHD - 120 Hz just last month, we were watching a show and the tv went blank. we still get sound but nothing else. does not respond to input changes from remote. i purchased a repair kit to swap out the T-Con Board, the Power Supply / LED Driver, and the Main Board. I swapped out all parts individually and tested as well as swapped all at once. nothing made a difference. i dont see anything beyond the LED backlight strips for sale. Does anyone have any information on what else i could try?
