Maintenance of iPhone 4 - Assembling it back

Hello all,

Long story resumed: I've got an iPhone 4 that, at least in the beginning, seemed a steal.

The device suffered from a serious fall (2 stores tall is what I have heard). My manager told me if I could recover the stuff inside of it, I could keep it since he already had bought another one for herself. Job done, she got her pics and I got myself an iPhone 4. Of course it was in shambles, so I got a new screen (the old one even got the flat cable ruptured) with the necessary tools to try and assemble it back.

I assembled everything as per instructions of iFixit and the iPhone still won't show any image. The display has been verified and tested by my supplier, so it's obvious the problem is on the device.

Sure, not everything is flowers, there are a few missing components which are coming later on (vibrator being one of these and the Speaker Enclosure other). Also, I'm missing a few screws. Still, the device IS booting up. I even got it listed under iTunes.

And so, my question is: could there be anything else making it not show any video on the display? Do I have to assembly it completely in order to provide some kind of "contact area" the display requires to start its magic?

How do you know the screen is good? Have you performed any test yourself? I have gotten "supplier tested" screens that don't work. Also when did you do this screen swap. There have been reports of the replacement LCD failing to work with the new ios7. If there is a way test it with a screen you know works. Than you will know you have a faulty replacement screen. Also make sure you didn't pinch the ribbon cable when installing the replacement screen.

Sadly I've seen the display being tested in front of me, since I kinda don't trust buying those through eBay and whatnot. Nothing against them dealers, it's just that this kind of stuff NEEDS to be tested. Also, I tried to be as patient as possible while assemblying, I'm pretty sure the ribbon has not been damaged during the assemble.

iOS 6 installed btw.

Any other tips?

If not, I guess that's that and I got an expensive 32GB pendrive, lol.
