Hello, So this isn't quite like all the other posts I've read about this. I replaced my iPhone 5 screen today and everything went smoothly, put the phone back together and it turned on fine, screen worked great, etc. Then I looked down and realized I hadn't put the metal cover that goes over the ribon cables back in. No big deal, just cracked it open again and screwed that plate down. But now when I go to turn it on, nothing. Until I plug it into power and still a black screen but every 6 seconds it makes the same chime when you first plug in a normal iPhone. What's going on It worked perfect then just stopped once I opened it back up again.
