I absolutely love my UN65KS8000, and it's probably the best set I've ever owned, picture quality-wise, so I'm concerned that the set is exhibiting some obvious issues with what looks like dark shadows or stains emanating from the bottom of the set along the left half of the display. It was only visible on white scenes months ago, but has definitely progressed to the point when it can be seen across any background. I'm assuming it will keep getting worse until it's too distracting, which would be a shame. What are my options for trying to fix or have this problem fixed? Or at least troubleshoot (besides power-cycling). Appreciate any help or assistance!
Do you notice this concern on all sources of the TV and have you tried replacing the HDMI cables for the TV?
I have indeed checked all sources (including using built-in apps), used different HDMI cables, and it's still the same issue unfortunately. I've tested it every way I can think of. The problem doesn't vary at all.
