I had an ipad 4 in for repair with the same problem a few weeks ago. I gave up on it as I think that the problem was a firmware corruption and that is not recoverable through the usb interface. You should look into a way to flash to the firmware directly to the chip.

Were they the original screens ? I've seen the digitizer connectors become loose on the cheap generic ones and this causes the screen to jump around and behave sporadic.

Yea.. that was the original screen.

You said that it's in dfu mode, right? That is a software problem the screen should be fine.
If it's not detected you should be able to get it back in dfu the way you normally enter dfu mode on an ipad.
