I own a Hitachi 50V500A 50 inch LCD rear projection TV. It's been great, but lately I've noticed that when I play DVD's, I get magenta colored lines outlining the actors and actually on the actors' faces. It's annoying. I've tried hooking up 3 different DVD's including a progressive scan, and nothing's changed. Has this ever happened to you? Does anyone have any thoughts on how I can get rid of this?
