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?

@jprado63009 if you replaced all of these boards (T-Con Board, the Power Supply / LED Driver, and the Main Board) and still do not have any video, then the issue is with the panel. there are no more boards that you could change. The only thing left would be the driver boards that are part of your panel. you could check to see if you find any burned or otherwise damaged component but ultimately it sounds like a bad panel. This of course assumes that you have all the right replacement boards and that those boards work as they should
