There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable near the black lines. Unplug the ribbon cable and look for black chips on the underside of it, I think they say 100 on them, you need to resolder both ends on each chip. Should fix the black line issue.
