After Screen Replacement, black screen and phone vibrating

Hey Guys,

I bought a white iPhone 5 replacement digitizer screen. Carefully moved the camera and home button over, attatched it and powered the phone up. It worked perfectly, however the home button was slightly off, so I shut it off and took of the screen and adjusted the home button.

I should mention I didn't reattatch it right there, I brought it home. I took good care of it, so I don't think anything broke but I could be wrong.

At home I tried reattatching the mew screen and it remained black. When I plugged it into iTunes, it does reconize the phone. It will either vibrate or make a notification noose every coulpe of seconds when plugged in.

So at this point I am assuming and kinda hoping I just damaged the. display. The owner of the phone stupidly threw the old display out, but I order a new one that is supposed to get to me quickly. Do you think I just damaged the display cables or something went wrong?

I tried holding the home and lock button for a while.. didnt seem to do anything

The phone isnt synced to my itunes so I am hesitant about restoring it, but I can probably back it up usong some other service. If restoring is what I need to do I can do that. Right now all I have is a black screen:(

Thanks Guys!
