I have a Dell Latitude laptop that I replaced a busted backlight and inverter on. When I boot the system I get two vertical lines on the left side of the screen. This was a recent purchase that was damaged before I got it and so I don't know if the problem existed before I got it. Where do these two vertical lines, purple and green, come from and how to I get rid of them? I would greately appreciate any help on this issue.
