I have exactly the same problem with an iphone 6 plus. Replaced a working cracked screen with a new one (used my camera, homebutton and backplate. When I switched it on the new one had a backlight but nothing on the screen except a bit of light. Put the old screen back on and it works ok. Returned the screen and bought another one from a different supplier with the camera and backplate already fitted and exactly the same issue! Is this coincidence I’ve had two defective screens with the same problem or is it something else?
