Hi All, I did a little investigation and removed the screen and found that it was not the screen I had given to the repair shop but another. I also found that by opening the phone and closing it again the black shadow disappeared. Does this mean that the screen is faulty or the ribbon cables >? I did manipulate the ribbon cable to try to recreate the fault but it didnt come back. the bend radius in one of the cables an be described as kinked. Should there be a kink or a bend ?
