Did we buy TVs at the exact same time? I just developed this issue today. I installed mine just before Thanksgiving 2021. I did buy an extended warranty and I bought from Costco so I'll get a repair or a replacement somewhat easily, but this is a pain.My C1 is fucked. White vertical line about an inch off from the left-side bezel. Broke three weeks after LG’s one-year warranty ended. Happened last week and I’m still waiting on a call as to whether or not they’re giving me a one-time courtesy panel replacement.
My advice would be to buy from a retailer that offers an extended warranty. I sure wish I did!
