It sounds like one or more board connections have come loose. Check for missing connectors in the backbox.

Quoted from Warbleboopie:

The only wire that's weird is some green one right at the bottom of the backbox but I think it's an extra ground?

Probably.
What are the three LEDs on the MPU doing? (The lower left rectangular board)

Quoted from Warbleboopie:

The power driver board has 4 red lights. I don't have a meter. No other boards have lights on in the backbox except for the top right board has one light on.

Well, that's the problem. Your MPU is not getting power.
Either the fuse, or the connector to the MPU or from the driver board is not on.
