Hello, As I already wrote in the headline, The display is no longer working. I didnt replace The Display it was in an mobile Shop, but The Shop didnt exist anymore. The iPhone makes some noise if i Connect it with an Charger. Is the Backlight circuit damaged or is the Screen faulty and cheap? (the Backlight is completly DARK!)
If you can’t make out an image at all on the display with a flashlight chances are it’s a bad screen.
