I have a 65" LG C9 for two months now and today I noticed a black vertical line on the image, as you can see in the attached photo. Is there any procedure I can try to solve this problem or do I already have to request a repair? Has anyone had this problem? Thanks.
I’m getting my C9 screen replaced today for the very same thing!
Sorry to say, you’ll need a new panel.
Also, I’m going through LG and not Best Buy’s warranty even though I have the extended.
LG tech that came out seemed to know his stuff better.
