Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Brightness uneven or insufficient
MediumSymptoms: Field dim or unevenly lit.
Root cause: Condenser too low or mis-centred, iris aperture wrong, dirty optics, or the illuminator lamp / LED aging.
Image not clear (contrast / definition poor)
MediumSymptoms: Low contrast or definition, one side dark, image moves while focusing.
Root cause: Wrong cover-glass thickness (needs 0.17 mm), no immersion oil where required, air bubbles in the oil, or the objective not fully in position.
Illuminator lamp / LED failure
MediumSymptoms: No or dim light.
Root cause: Lamp / LED at end of life, or a rheostat / driver fault.
Focus / stage mechanism wear
LowSymptoms: Coarse / fine focus slips or binds, mechanical stage stiff.
Root cause: Worn focus clutch or dried stage grease.

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: Uneven or dim field
- Raise and centre the condenser and set the iris aperture.
- Clean all optical surfaces.
- Check the lamp / LED and replace if dim.
- Verify Kohler alignment.
- Re-check across objectives.
Symptom: Image not clear
- Fit a 0.17 mm cover glass and place the specimen level, clipped by the clamp.
- Use the correct immersion oil with oil objectives and clear any bubbles.
- Remove oil from dry objectives.
- Set the iris aperture and re-centre the condenser.
- Confirm each objective seats fully in the light path.
