Why is my screen black? I know it works and so does the battery.
I replaced the rear case of this phone I’m working on. And have also replaced the screen. I was told it just needed a new screen when I bought it and I thought that would suffice. I have tried using the battery and screen from another phone I have fixed and know to be working. But it stays black. I’ve tried shining a bright light to see if its the backlight and I can’t see anything on the screen. When I try to restore it on itunes it recognises the phone and says its locked with a password. I’m not sure what’s going on the but the previous rear case was slightly bent. I think there is some problem with the logic board, specifically the LCD connector. Is there a way I can test this or diagnose it?
