Very interesting, do you have another digitizer to try? If you don't, then you can try cleaning the contact with some alcohol, but I assume you did that. Make sure the ribbon didn't get pinched while closing it up. Latches closed down I assume. Could be a bad digitizer, could be a silly error during install. Best to tear it down and check again. Good luck.
