Is the two Ribbon cables the connection between the touchpad and the control board it doesn't come off it is on the glass panel with the knobs. or is the white wiring harness the connection?
I am not sure what you mean by the above.
The ribbon cables are hard wired to the keyboard.
Have you tried removing power from the unit for 10 minutes or so and then trying it again to see if it will reset.
These things are very sensitive to ground connections so I would check all connections which go to the frame.
You may want to try the following.
Connector Cleaning / Checking
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.
