Hi Mark,

Have there been any recent power outages or thunderstorms which may have damaged the control panel by causing a power surge?

If the controller pad suddenly stopped working, then either it has suffered some damage or has an internal fault, and will need to be sent for repair or possible replacement.

As it is over 8 years old, it may have suffered a sudden failure due to a faulty component - it would need to be tested at a service center to locate the faulty component and replace it.
