This is hard to explain so I didn't know how to search for this on here. I have a Panny 50" 60U. I've noticed on numerous times that when the screen is mostly white or a light color that if there is a dark object in the middle, a shadow or a light gray color will band out of the sides of the dark object that is equivalent in height to the object and goes out from the left and right to the edge of the TV. For example, when I watch "The Office" and a confessional is going on there are usually blinds on the window behind the person. I will see dark bands that are equivalent in height of each blind come out and display on the walls of the office. Its very subtle but I notice it. This often happens when text is displayed on the screen. Any help here? Is my TV defective?
