Lathe CNC Control Box Fault Diagnosis

My lathe CNC is experiencing complete machine downtime due to issues with the control box. The controller and relay are both flashing, but there are no specific error codes or messages. I need an electrical engineer based in London to diagnose the problem and help get the machine back up and running.
