Powakaddy CT6 screen error

[ljh100]

My Powakaddy CT6 has failed to work today. Battery is fully charged

Initially control panel was blank. Later attempts resulted in screen error display as per image attached.
Is anybody able to advise the likely reason for the fault.

Thanks

Could be a faulty motherboard, which normally results in the entire screen not coming on and the trolley not working (although battery light will still be on).

Just in case it helps anyone else an update to my original post...I look my trolley to a repair agent. The engineer initially advised it could be the controller or handle. Further investigations identified it was the controller which he was able to replace from stock items.
