iPhone Won't Turn on After Screen Replacement

[Mythlin]

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.

Sounds like a loose connection somewhere. I would re-open it and double check everything.

I've tripled checked everything, even took my old LCD replaced all the necessary components on it and it doesn't work either.. Which it did when I started was just cracked

You assume the risk when opening up the device yourself.
I know this doesn't answer your question, but if you cant find out why it does this, an Apple store tech wont replace the screen, or phone for you as you operated on it yourself.

Hopefully you find whats wrong
