Digitizer Not Responding After Professional Replacement

I put a new screen on the iPhone and the digitizer will not respond. I tried to reset the device and everything and nothing fixes the problem.

Thanks for the help!

There will be a few environmental variables here:

- Each screw is unique in size, differentiating by 0.2mm each. If the order is mixed up, a long screw could have penetrated the board.

- The flex cables are very fragile, and may have been damaged during the process.

- Pride aside, it's safer to replace the entire assembly rather than just one part, such as the screen but not the digitzer or fingerprint IO cable. Or, at least have the items on standby.

- Miniaturization of Electronics has placed much greater need of ESD protection, ESPECIALLY on iDevices. I wear Nitrile gloves, i have an ESD wrist strap, I work on an ESD mat, both items connect to a small junction box that grounds at the wall outlet center-screw. Nothing mysteriously breaks, ever - You should do these too. :)

What's ESD? Is there a guide for replacing just the glass? A guide for the digitizer? Where can I get these parts? What are Nitrile gloves and where can they obtained? Why do the center screw?
