Hat geantwortet auf: White Vertical Lines on LCDI had this problem as well after replacing my screen. White vertical lines down the length of the screen and an unresponsive digitizer. It turned out that the problem was that the flex cable connector was not seated correctly. This is the first cable you connect for the screen (closest to the top of the phone with horizontal orientation). When I removed all three connectors and reseated them, the screen worked perfectly.
