Most common cause of this is long screw damage . It is likely that the screen has been removed and the screws holding the LCD connectors in place have been put back in the wrong order. The screws are different lengths, and if not put back in the correct positions it will damage the tracks in the bottom of the screw holes.

After you replace the Digitizer if you are getting random key presses it is likely to be because Kapton tape has not been applied to the edges of the digitizer. You need to cover the silver strip around the edge of the digitizer with kapton tape before reassembling. Works every time.

There is a way of making the Wifi/Bluetooth Antenna replacement much easier. If you have a steady hand and a soldering iron simply desolder the connecting cable from the bottom of the antenna and solder it back onto the new antenna. This means there is no need to dismantle the iPad and the repair is much faster. Hope this helps :-)
