I have a 50" Sony Wega and recently noticed about an inch high reddish bar at the bottom of the screen. The bar extends the width of the screen. My 4 year old son left Star Wars Lego on (XBOX 360, what else), but the console is set to dim after 15 min. of inactivity which it did. Is this a burn in problem or pixel reconfiguration? It's been evident for about 2 weeks. It doesn't seem to be getting worse. You can also only notice it when the screen is displaying a light color. It also can be seen when the cable is on. Any help out there?
