I am not 100% sure what the issue is but I do believe it is the battery. If it works fine on the charger while being powered but taking it off stops everything from working, it would make sense that it is the battery not pushing enough power to make the device work properly.
I would hang out a bit and see if some others can give better advice, just in case
