What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting Portrait VSM monitors when the touchscreen is unresponsive or intermittently fails to register input. Common causes often involve external factors like power fluctuations, screen contamination, or loose connections rather than internal failures. Following these steps ensures safe, logical troubleshooting and helps determine when escalation is required.
Step-by-Step Troubleshooting
Verify Device Power
- Ensure the monitor is powered on and the battery has sufficient charge.
- Confirm the AC power adapter is securely connected and the outlet is live.
- Why: Insufficient power can cause the touchscreen controller to fail.
Inspect Screen Surface
- Clean the touchscreen with a lint-free cloth and approved disinfectant.
- Remove any protective films or screen covers that may interfere.
- Why: Dirt, moisture, or adhesives can prevent proper touch registration.
Check for Obstructions
- Ensure no objects, gloves, or moisture are in contact with the screen while testing.
- Why: Physical interference can cause the touchscreen to appear unresponsive.
Perform a Soft Reboot
- Power off the monitor fully, wait 30 seconds, then power back on.
- Observe if the touchscreen responds during boot-up.
- Why: A temporary software or firmware freeze can cause touchscreen issues.
Inspect Cables and Connections
- If accessible externally, verify all connectors from touchscreen to motherboard/module are seated correctly.
- Check for loose or damaged cables (without opening the monitor casing unnecessarily).
- Why: Loose connections can interrupt touchscreen signals.
Test with External Input (if available)
- Some Portrait VSM monitors allow temporary navigation via buttons or external input.
- Why: Confirms if the issue is strictly touchscreen or system-wide input failure.
Software/Firmware Check
- Confirm the monitor firmware is up to date (via GE-approved process).
- If outdated, plan for software update in coordination with IT/CE.
- Why: Firmware issues can affect touchscreen responsiveness.
If the Problem Persists
External causes are likely ruled out. Device should be:
- Removed from service
- Labeled “Out of Service”
- Sent for bench evaluation or GE-authorized repair
Stopping at this point is proper troubleshooting to avoid patient risk or unnecessary internal disassembly.
Clinical Use Tip
- Do not attempt touchscreen troubleshooting while the monitor is on an active patient.
- Move the patient to a functional monitor before intervention.
- Only operate the monitor for testing when it is safe and patient care is not compromised.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Touchscreen does not respond to any touch input; monitor cannot be navigated.”
Cause
What was observed during troubleshooting.
Example:
“Screen surface clean, power confirmed, rebooted, external connections verified; unresponsive persists, likely internal touchscreen or controller fault.”
Resolution
What action was taken.
Example:
“Device removed from service, labeled Out of Service, sent for bench evaluation with GE Healthcare service team.”
Helpful Details to Include
- AC outlet verified with multimeter or known good device
- Battery charge confirmed
- Screen cleaned and inspected
- Soft reboot performed
- External buttons/navigation tested
- Firmware version noted
- Final device status: Out of Service
Final Thought
Touchscreen responsiveness is critical for safe patient monitoring. Using a structured troubleshooting approach protects patients, ensures logical escalation, and provides clear documentation for future service and repair. Properly identifying when to escalate avoids unnecessary risk and preserves device integrity.
That is successful troubleshooting.
