What This Guide Helps With
Identifies causes of incorrect color, tint, or failed white balance that affect image accuracy during endoscopic procedures.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Confirm the camera system is not in use on an active patient. Move the procedure to a backup system before troubleshooting.
Verify Connections
- Check the camera head is properly seated in the processor port.
- Inspect the cable for damage or loose connectors.
Expected Outcome: Secure connections should allow recognition of the camera and enable color settings.
Check Processor Settings
- Access the VISERA Elite processor menu and ensure white balance mode is selected.
- Some procedures may require manual or automatic white balance reset.
Expected Outcome: Processor confirms white balance function is active.
Clean the Camera Lens and Light Guide
- Wipe the distal lens and light guide with approved lens cleaning solution.
- Residue or debris can skew color readings.
Expected Outcome: Clear lens improves accuracy of white balance.
Re-run White Balance Procedure
- Use the processor’s white balance function per standard protocol.
- Follow prompts exactly; ensure room lighting is adequate and target surface is neutral-colored.
Expected Outcome: Color calibration completes without error.
Swap Accessories
- If issues persist, try a different camera head or light cable if available.
Expected Outcome: Confirms whether the problem lies with the original head or processor.
If the Problem Persists
Common external causes have been ruled out; internal processor or camera head calibration may be faulty. Remove device from service, label Out of Service, and send for repair or bench evaluation. Knowing when to escalate prevents further procedural delays or patient risk.
Clinical Use Tip
- Never perform white balance on an active patient; always use a test surface or neutral target.
- Ensure adequate room lighting to avoid calibration errors.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Endoscopic image colors appear incorrect, unable to complete white balance."
Cause
What was observed during troubleshooting.
Example:
Camera head and processor connections verified; manual white balance fails; lens clean.
Resolution
What action was taken.
Example:
Reattempted white balance with alternate accessories; issue persists; device removed from service and sent for repair.
Helpful Details to Include (If Known)
- Processor display messages
- Indicator lights during white balance
- Lens or cable condition
- Test target used
- Final device status (Out of Service)
Final Thought
White balance issues may seem minor but affect surgical accuracy. Logical troubleshooting—from safety to connections to settings—ensures proper escalation and patient protection. Document all steps clearly.
That is successful troubleshooting.
