I Have a new Toshiba 51hx83 I've noticed a dull section in the upper center of the screen. It's about 6 inches in diameter and does not seem to be on the screen but behind it. the picture is perfect and the spot not visible when the tv is on. It's only seen when the tv is off. Is this some part of the inner works that I'm seeing and is this normal or does this seem odd. I have not called for repair as the picture is fine but have never seen something like this on other sets.
Anyone have any thoughts.
