  If the Essilor Instruments Measuring Instruments has no illumination, first ensure the power cable is correctly connected to the power socket. Then, check if the plugs on the power box or lamp cap are loose, and insert them firmly if needed. If the issue persists, the bulb may have burnt out and needs replacement, or the fuse may have blown, requiring a fuse change. Also, ensure the bulb is properly assembled and the filter lever is correctly positioned, not in the middle or gray filter position. Finally, check that the brightness adjustment knob is not at its minimum setting.
