What This Guide Helps With
Addresses low illumination, flickering, or LED failure to ensure consistent and safe visualization during procedures.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm the system is not in use on an active patient.
- Move the procedure to a backup light source or camera system to prevent risk.
Check Power Source
- Verify the light source unit is properly connected to a live outlet.
- Confirm power switch is on.
- Expected Outcome: Unit powers on without error indicators.
Inspect Cables and Connections
- Examine fiber optic or light cable for damage, kinks, or loose connections.
- Ensure connectors are fully seated on both camera and light source.
- Expected Outcome: Properly seated cables restore normal illumination.
Check Lamp or LED Status
- Observe any LED indicators or display messages on the light source.
- Replace the lamp or LED module if indicated by the system.
- Expected Outcome: Light illuminates steadily without flickering.
Swap with a Known Good Light Source
- Connect the camera head to a verified working light source unit.
- Expected Outcome: If illumination returns, original light source may be defective.
Verify Settings and Mode
- Ensure brightness and mode settings are correctly configured on the camera and light source controller.
- Expected Outcome: Properly configured settings restore adequate light output.
If the Problem Persists
External causes (power, cables, lamps) have been ruled out.
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Recognize that continued troubleshooting without proper tools may risk further damage.
Clinical Use Tip
Never attempt light source troubleshooting while the patient is under procedure.
Always confirm backup illumination is available before swapping or disconnecting light cables.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"OR staff reported flickering or dim illumination from the Image1 S light source."
Cause
What was observed during troubleshooting.
Example:
"Fiber optic cable kinked and LED module nearing end of life."
Resolution
What action was taken.
Example:
"Straightened cable, replaced LED module, verified stable illumination."
Helpful Details to Include (If Known)
- Outlet tested and confirmed live
- Cables swapped and inspected
- LED status indicators
- Light intensity observed and recorded
- Final device status: fully operational
Final Thought
Patient safety and uninterrupted visualization are critical. Begin with basic external checks, escalate only when necessary, and document all actions. Proper procedure protects both patient and equipment.
That is successful troubleshooting.
