(Traded) 60" Samsung TV - kinda faulty

Have a working but sorta faulty TV. Model UN60EH6000FXZC. Works great but there is a single blue vertical line on the left side. TV works fine except for that line. I used to keep in the basement beside my workout equipment for fitness videos. Unfortunately I'm moving soon and I'm trying to downsize. Maybe you're techie and can fix it?

Missing the original remote but I'll include another Samsung remote that I picked up that works great.
