Root cause: Condenser aperture stopped down too far (should be 70-80% of objective N.A.), condenser not focused/centred, or the optical-path lever not on the 100% eyepiece position.
Image will not come into focus / eyepieces not coincident
MediumSymptoms: Cannot focus even with the objective raised, or double image.
Root cause: Stage attached incorrectly, or interpupillary / diopter adjustment not performed.
No power / lamp does not light
MediumSymptoms: Dead unit or the lamp will not illuminate.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Field too dark or uneven
- Open the condenser aperture to ~70-80% of the objective N.A.
- Focus and centre the condenser so the field-diaphragm image is sharp on the specimen.
- Set the optical-path lever to the 100% eyepiece position.
- Clean all optical surfaces.
- Re-check Kohler alignment.
Symptom: No power / lamp will not light
- Reseat the power cord at both ends.
- Turn off and unplug, wait 30 min, then check/replace the halogen lamp.
- Check the mains fuse.
- Refit the lamphouse cover fully before switching on.
- Confirm illumination and brightness control.
