Did you get it working i have the same issue? the picture displays with the original screen but not with the new one. i have tried 3 different screens and get the same on all of them. i even tried updating to the latest software but only get a black screen, no picture.

When i have had this on iphones i just so a reset by holding down the buttons and the screen starts to work.

Please someone help

Same here! I also findout that lcd still works, if you get some flashlight on screen in a dark room, you will see that only backlight not working when battery plugged. I tried to baking it but it still didn't worked. It's obvious that backlight could properly operate as it works when you take off the battery. I'm looking for solutions, if I find any, will wrote it here.

Did someone find a solution to this? I also replaced my screen and it keeps black solid when I turn it on, even with the touch working properly.
