I have a 49" LED lit LG 4K lcd tv, about 2.5 years old. Really nice tv. Today I had some free time, and decided to watch this weekend's IMSA race on YouTube (No commercials). It's a 2 hour 40 minute race, that I watched over about 3 hours or so. I had to pause it a few times, and the tv will default to a screensaver after about 5 mins. However, I noticed toward the end of the race that the screen now has burn in all along the left side where the positions of the drivers are listed. These are short horizontal lines, some of which never move or shift even when the driver names change. And there were no commercials, so it stayed up the whole time. I've watched races in their entirety longer than this several times and this has never happened. Will this disappear after awhile, or is it time to TV shop?
