I’ve done a few iPhone 5s screen replacements and battery replacements. I have one now that was working fine. I replaced the screen and the battery, and now I get no screen. The phone turns on, because it’s recognized by iTunes, but nothing else. I’ve tried different screens, and still nothing. I don’t know what else to try.
When u try a new screen and don’t turn the iPhone off you need to do a hard reset by pressing power and home or just disconnect and reconnect battery.. Falling that check for damaged pins on the motherboard were screen plug in
