Hi Francis,
The frames don't roll, they stay as they are supposed to. I have horizontal white lines that roll up the screen. They distort the picture as they move up the screen, I'd like to fix that. Does this info help?
Thanks,
Joe
Francis,
The picture is stable and doesn't move. The lines are from side to side and roll up the screen from bottom to top. There are two adjustments on the back of the cabinet, neither one has an effect on the rolling lines.
