I'd look over all the connectors and wiring harnesses of the whole thing, and see if there is any obvious damage, bent pins, etc. Maybe open the box itself and see if theres any signs of damage to the board? Cracked solder joints, etc.

Not sure if you just purchased it new but if you did it might be worth trying to get a refund or exchange.
