What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting situations where the Infinity Delta monitor’s display, touchscreen, or keypad is unresponsive, partially responsive, or showing abnormal behavior (flickering, frozen screen, or incorrect inputs). The focus is on external checks, system settings, and safe escalation, rather than internal electronics repair.
Step-by-Step Troubleshooting
Check Power and Battery Status
- Ensure the monitor is powered on and battery has sufficient charge.
- Observe any low battery or power warning indicators.
Why: Low power can cause unresponsive displays or input failures.
Inspect Display and Touchscreen/Keypad for Physical Damage
- Look for cracks, scratches, liquid spills, or debris.
- Ensure connectors are free of dust and moisture.
Why: Physical damage or contamination can prevent proper touch/key response.
Perform a Soft Reboot
- Power cycle the monitor using the standard shutdown and restart procedure.
- Observe if display and input responsiveness returns.
Why: Temporary software glitches often cause touch/display failures.
Check Display and Touchscreen/Keypad Connections
- Verify that internal cables (if accessible without disassembly) are seated properly in docking stations or external modules.
- For bedside monitors, ensure keyboard/touchscreen overlays are properly aligned.
Why: Loose connections can cause partial or total input/display failures.
Test with External Display or Input (if supported)
- If the monitor supports an external display or keyboard, connect and verify functionality.
Why: Helps isolate whether the issue is with the touchscreen/keypad versus internal processing.
Check Software/System Messages
- Review any error codes or on-screen messages.
- Confirm software version is current and not flagged for known display issues.
Why: Some failures are software-related and may require an update.
If the Problem Persists
After verifying power, physical integrity, connections, and system software:
- Remove the monitor from service.
- Label it Out of Service.
- Send to manufacturer-approved repair or bench evaluation.
Clinical Engineering Note: Do not attempt internal board-level repairs; this ensures patient safety and preserves device warranty.
Clinical Use Tip
- Never troubleshoot display or keypad issues on a patient-connected monitor.
- Move the patient to a functional monitor before performing any checks.
- Ensure alarms and monitoring continue uninterrupted during troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Monitor touchscreen and keypad not responding; screen frozen.”
Cause
What was observed during troubleshooting.
Example:
“Power verified, cables seated, soft reboot attempted; display remains unresponsive.”
Resolution
What action was taken.
Example:
“Monitor removed from service, labeled Out of Service, sent for manufacturer repair.”
Helpful Details to Include
- Power source tested (AC and battery)
- Physical inspection notes (cracks, debris, moisture)
- Reboot attempts
- External display/input tests
- Any error messages or codes observed
- Final monitor status
Final Thought
Patient safety is paramount. Logical, stepwise troubleshooting prevents unnecessary delays in care while ensuring defective monitors are safely removed. Thorough documentation supports maintenance tracking and future preventive measures.
That is successful troubleshooting.
