Ответ на "iPhone 4 screen is black after replacement"I've had the same problem. My phone was absolutely fine, till I smashed the screen. It still worked fine, I just obviously couldn't see properly due to the broken glass. So I went to get a new screen put on, and it was fine and dandy for about a week - then the screen went completely black. But it was still receiving text messages and phone calls. I took it back to the guy who fixed it, he opened it up and played around with it and it turned back on. Sure enough, it only lasted a week - now it's back to black and useless. Super annoying, did the guy tear a cable or something? Is it even worth fixing? I'm lost and have tried everything.
