How to fix a National Microscope when the light fails to operate?
- RRobert SmithJul 28, 2025
If the light on your National Microscope isn't working, start by checking all electrical connections from the AC wall outlet to the microscope's input. Ensure that all switches and intensity controls are correctly positioned. If the transmitted LED bulb is burned out, replace it. For an incidental LED bulb that has burned out, send the lamp assembly to National for bulb replacement.
