update, I tried it with an S-Video cable and it did the same thing. Also it seems to only happen on channels that are 4:3 even when it's an HD channel broadcasting in 4:3 (something like Seinfeld). So it happens on HD and non-HD channels. The white line stops where the 4:3 stops also, so it doesn't run across the whole screen.
I also tried a different cable box and same thing.
Please let me know if I should return this tv?
Thank you.
