I have a dim/dark area in the center
I hate to threadjack but this looks similar to my UN55KU7500FXZA. In short the TV works fine (powers on, HDMI works, audio, smart apps etc.) but I have a dim/dark area in the center that sometimes appears immediately, other times it appears after maybe 30 minutes of use. The dim/dark area still shows a picture with color and everything but is just dim/dark. (There are some very bright areas on the edges as well but I can live with those.)
Is this a reasonably easy problem to fix?
I played a screen test video and took a picture of the TV.
