Re: Lg 65UH655O BARS ON THE SCREEN
More likely to be panel.
You need to open up the back and see if the T-CON, tab bonding boards are on the bottom edge of the LCD panel or not.
Did anyone spray the screen with cleaner to clean the screen?Never stop learning

Re: Lg 65UH655O BARS ON THE SCREEN
I had the same exact defect on a little older LG, it's a common issue on LG panels, the problem is on the source driver cof that began to slightly desolder, i have fixed it for some minutes but i had too much hurry to remount the bezel, the story is long, i ended cracking the cof due to shim mal positioned, its not easy when there is not a confortable plane of work. I think a better technique than mine can be used to fix it much faster and better with the use of a simple soldering iron stylus.
the other side should have shown a picture.
NOTE: A COF is a chip! not the band that holds it.Last edited by Davi.p; 08-08-2020, 05:20 AM.
