Try to run the service test.
Could be the board is shot again.
I am not sure about the specifics of how this configuration error works but perhaps one of the other devices is open and it comes up because it cannot see it.
Try turning the breaker off for 5 minutes or so to see if it will reset
Try the connector cleaning
Measure the other components with a meter
If all the above are OK then odds are the board is gone again.
Connector Cleaning
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
