I'm not sure but i think the screen they replaced in my TV last week is defective or something. It's near the top of the screen where it looks like there's a line that goes across the screen and it looks like it gets a little bit brighter above it. It's a little hard to explain but i noticed it a couple of times before (i think), nothing major, but when i was watching HTTYD, it really showed during the foggy scenes. Other then that, you can't see it.
