Ok I'm not sure what's caused this but here goes.
The past couple days, verticle green lines just appear on the screen at random times. When I'm online it's usually 10x worse. Like when scrolling up and down the lines get progressively worse until they practically are over a good part of the screen. The lines go away depending on what web page i'm on, but there are 7 lines across the screen, about 3 pixels wide each in various places on the screen that just will not go away. I've tried demagnetizing the screen but the lines will not go away. So I figured I'd ask for some help. Thanks for any advice.
