There is nothing wrong with the screen itself. When you first power up there is no line at all the "Compaq" logo appears and you can go into BIOS and there will be no lines.
Once the windows screens start to appear the lines appear, I've used both the Tv out and VGA out and the lines are still there.
Possible the graphics chip on the mainboard gone then?
What could it be?? Any ideas??
