Has anyone else had issues with a red line appearing on the screen? If so, were you able to repair it and what was the cost? This happened a week or so ago on mine. It's just out of warranty by a few months and were were told it would be between $1000-$1200 to repair. At that point I might as well buy another TV. I have 5 other regular Samsung TV's and have never had an issue, so didn't buy the extended warranty. It's super disappointing that I paid over $1600 for a TV that apparently is already needing to be replaced in 1.5 years.
I am dealing with the same issue with my Samsung 8k tv. Had it for about a year and a half, and now have two thin vertical rows of red lines. Soon after they appeared, the tv began power cycling. I hit the power button on the remote and a blue screen came up for a few seconds, then it powered off, then back on to blue screen, then off, etc, all on its own. I had to unplug it to get it to stop.
I spoke with Samsung support and scheduled what was to be a very expensive in home visit, but ordered a replacement OneConnect cable from Amazon for my tv. When it arrived I replaced the cable and it resolved the power cycling issue but the two red lines remain. From what I have read online it sounds like it could be ribbon cable connections plugged into one of the boards in the tv, but I am not confident trying to resolve that issue myself. I'm happy I can power on my tv again and will deal with the red lines soon. Good luck!
Nope, that's a main board error. You can't troubleshoot that, it's just fried. You either need a board replacement or a whole TV replacement if under warranty. If not I'd ask for the price of the board to see if it's feasible to get that or just a brand new TV
