White lines all over my screen

I've got the same thing but fortunately the lines are only at the top and are about the same size as the font.

For example if there is a 2" high (white) caption at the bottom of the screen there will be very thin white lines, very close together like a barcode, at the very top of the screen matching the length (width) of the words. If there is a space in the caption, there will be a space in the white lines.  Thankfully, they are ghost like so they are easy to ignore.

Note: It can also happen with bright colored graphics.
