If the Optimum monitor's digital display isn't showing anything, first ensure the power cable is securely connected and the power switch is turned on. Verify that the voltage is within the range of 230V +/- 10%. If these steps don't resolve the issue, unplug the device. Also, check the fuse and replace it if needed. Finally, make sure that the machine tool and the position display cover are well grounded.
