Re: LG 55UK6750 PLB ...Help Please

If I'm looking at what I think I'm looking at the board where the ribbon cables are connected but no connectors, that's your address board, or the display panel itself. the tape trick and all that jazz just bypasses shorts in your screen.
BUT backing up and just thinking of your symptoms, I'd suggest main board or tcon as those are the only two that will control the picture other than the screen.

So I work at a TV Parts distributor and I have a customer who has a TCL 65S401TDAA GTC002311A. His original issue is sound, no picture. We have sent him 3 main boards, we know they are good, as they are all doing the exact same thing, but they are distorting his picture. He has replaced the TCON also which made no difference in his symptoms. But here is where it gets weird, including some of his emails: "
I received the second replacement main board, but I'm having the exact same distorted image as with all three boards. I have tried each of them with the original and the replacement...

Hi,
NJ, 26 female, from Kentucky.
I know pretty much next to nothing except what I've been able to learn from working at a TV parts business. But that's exactly why I joined, to further my knowledge.
