Unfortunately, I don't have any way of knowing what would be causing this.
Is it happening on other inputs, or just the one the TV is running through? I'm wondering if it's a cable reset or box/line interference...?
Every now and then, I get a red line our red shadow in the middle of my screen. Sometimes the top, middle our bottom but always in the middle of the screen. Its not random because when the same commercial comes on the red appears in the same area each time. It seems to show up during certain scenes. Such as a solid white or gray back ground or when watching the news when and theres a close up of someone and theres not very much movement. This is very hard to explain. My warranty ran out 4 months ago (of course)so I need some help. Any advise would help. Thank you.
