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.
Illumination fault
MediumSymptoms: Light out, dim, flickering, uneven field, colour shift.
Root cause: Halogen bulb or LED module / driver at end of life, or a light-guide / power fault.
Focus / magnification-changer fault
MediumSymptoms: Fine focus slips or binds, magnification changer sticks, image not sharp.
Root cause: Worn focus drive or a magnification-changer detent fault.
Stand / arm / brake drift
MediumSymptoms: Head drifts down, will not hold position, arm joints loose.
Root cause: Spring-arm counterbalance or friction brakes out of adjustment.
Green (red-free) filter / filter-wheel fault
LowSymptoms: Filter will not engage or is stuck in place.
Root cause: Worn filter mechanism.
Camera / video / capture fault (video colposcopes)
LowSymptoms: No or poor image, capture software will not connect.
Root cause: Camera, its cable, or the imaging PC.

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: Dim or no illumination
- Replace the bulb / LED module with the correct type.
- Check the driver / power supply and connections.
- Inspect the light guide (if fibre) for dark fibres.
- Confirm even, full-brightness output.
- Replace the driver / power supply if output stays low.
Symptom: Head will not hold position
- Adjust the spring-arm counterbalance for the head weight.
- Check the friction brakes at each joint.
- Replace the counterbalance / brake kit if adjustment does not hold.
- Cycle the arm through its range.
- Confirm the head stays put at working positions.
