What This Guide Helps With
Addresses loss of video signal or corrupted output over HDMI/SDI, ensuring surgical monitors receive accurate visualization for safe procedures.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Confirm the system is not connected to an active procedure. Move the patient to a backup display or camera system to prevent procedural risk.
2. Verify Output Connections
- Inspect HDMI/SDI cables for visible damage, kinks, or loose connectors.
- Confirm the correct input is selected on the surgical monitor.
- Expected outcome: Properly seated and undamaged cables should allow signal transmission.
3. Test with Alternate Cables and Monitors
- Swap the HDMI/SDI cable with a known working one.
- Connect to a different compatible monitor if available.
- Expected outcome: If video appears, the issue is likely cable or monitor-related.
4. Check Camera Hub/Processor Output Settings
- Access the Image1 S output settings menu.
- Ensure HDMI/SDI output is enabled and set to the correct resolution/format for the connected monitor.
- Expected outcome: Correct settings restore video output.
5. Power Cycle the System
- Turn off the camera system and monitor.
- Wait 30 seconds, then power them back on.
- Expected outcome: Temporary glitches may clear and signal restored.
6. Inspect for External Interference
- Ensure no high-power devices or long cable runs causing signal degradation.
- Expected outcome: Reducing interference may restore stable video.
If the Problem Persists
External factors have been ruled out. The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Knowing when to escalate avoids unnecessary risk and damage.
Clinical Use Tip
Never attempt HDMI/SDI troubleshooting on a device actively in use on a patient. Always provide an alternate system to maintain continuous surgical visualization.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"HDMI output not displaying on OR monitor during procedure."
Cause
What was observed during troubleshooting.
Example:
"HDMI cable was damaged; output settings on processor were misconfigured."
Resolution
What action was taken.
Example:
"Replaced cable, corrected output settings, verified video on monitor."
Helpful Details to Include (If Known)
- Cable type and length tested
- Monitor model and input port used
- Indicator lights on hub/processor
- Any unusual video artifacts, flicker, or color distortion
- Final device status
Final Thought
Effective troubleshooting prioritizes patient safety, logical checks, and clear documentation. External factors often cause HDMI/SDI failure; knowing when to escalate ensures safe, efficient resolution.
That is successful troubleshooting.
