    I have a similar problem, except mine has a black rectangle at the top of the screen, and the missing horizontal video lines are dispersed like a double image just below in the area that's viewable. It's the JVC AV-27020.

This is a function of your set-top box (STB), and has nothing to do with the TV. I know several FiOS users with the same trouble, and it's annoying but there isn't anything you can do to "fix" it.
