Hurco bmc30htm console issues

I picked up an old bmc30htm here recently and have been going through it cleaning and fixing things, finally got to the point of firing it up and I’m having a big issue with the the console board keys not working . So basically I can’t even put it in manual mode to power it all the way on. I’ve used an external keyboard to go into the hidden menu and run the keyboard check and basically none of the keys register.

Has anyone seen a similar issue or have and idea for troubleshooting it? Thanks!
