65 is logic card, faulty initial setting
possible causes are:
faulty DIP switch (DSW) setting on logic card
model not set
or faulty logic card
i would check all your connector plugs, wiring associated with them and check the DSW switch and make sure its working, wiring on it is good, no loose or broken wires.
