Most of that flew cleanly over my head. I think you're trying to deal with a line on your LCD. Have you made sure the LVDS cable is plugged in to the logic board securely? If it is, then most likely you need a new LCD panel. You can actually open the LCD panel by throughly heating small sections of the outer edge of the glass, and carefully yet firmly prying the glass up with suction cups. But the LVDS cable is easiest to check.
