Ok so I replaced my led back lights but when I put back together my led lights turned on and screen was black. Then at bottom mid of screen redish yellow vertical lines start slowly appearing. Tv automatically turns on as soon as I plug it in. I do not believe I damaged the panel. I however unplug the t con board while tv was on and lines go away and theirs a solid black screen with back lights working. However, I’m Not sure if I install the fuser films and sheets in right order or not. I think I did but not positively sure. As soon as I get a day off work, I will post pics/ video.

There’s also no sound. When I plug it in tv will immediately turn on, on it’s own. I can’t choose a channel, do not see any display nor sound. The longer I leave it on the more lines show up on the tv.
@jerelbug double check your work. Make sure that you have all wires reconnected properly. Let us know how you handled the panel when your replaced the backlight. For now, it does look a bit like a panel issue. Double check the TAB on this and see if the ribbon cables have come loose.
hey i am having the same problem i went from having a tv that wouldnt turn on to a tv that looks like an iron gate with some color is in the middle plus the tv turn on automatically. i have no control with power or anything
