What have you tried so far?

I replaced the tough pad and this did not repair the issue.


There are a few things to try.
1) Unplug unit from power for 5- minutes to see if the board will reset. Plug in and if problem is still there go to #2
2) Make sure that keypad cable on main PCB is in plugged in all the way . If it is go to step #3
3) Make sure connector (CN06) on Main PCB or PCB board is plugged in securely. If still not working – Replace the main PCB board.

See service manual link below on page #38 for complete directions.
