Sharp LC42D64U - strange line of static in standard def

I have the same problem I believe. It's not your tv, it's the show/commercial. I get that once in a while on SD channels and during some commercial that are not in HD on the HD channels. The only way to fix is either Stretch the Image, or I think you might have an option in your Dish Receiver to move the picture. Kinda like on a pc monitor, you can move the picture up down left right, I think you can do the same with your Dish Receiver. But, move it too high and you might get a missing line on the bottom. It's a work around...not the best solution, but hopefully one day SD programming will get their act together.

the line of static is closed captioning information sent by the broadcaster. It's normal to see when watching SD material in Dot by Dot mode. Hit stretch to overscan enough to get rid of it if it bothers you.
