What This Guide Helps With
Addresses unresponsive or erratic touchscreen and control panel behavior caused by calibration drift, connection issues, software faults, or environmental interference before assuming internal hardware failure.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Confirm the system is not actively imaging a patient.
- If urgent imaging is needed, move the patient to another available system.
2. Check for External Interference
- Ensure no strong magnetic fields or nearby devices could affect touchscreen performance.
- Remove any cleaning wipes or protective films that may obstruct touch response.
3. Inspect Connections
- Verify the control panel cable and connectors are fully seated.
- Check for visible damage to the ribbon or harness connecting the panel to the main unit.
4. Perform Software Restart
- Reboot the ultrasound system using proper shutdown procedure.
- Observe if touchscreen and control panel respond correctly after restart.
5. Calibrate Touchscreen
- Access system settings to initiate touchscreen calibration.
- Follow on-screen prompts and test response accuracy.
6. Update Software / Firmware
- Check for available system updates addressing touchscreen or control panel issues.
- Apply updates following manufacturer instructions.
If the Problem Persists
External causes have been ruled out. Remove the system from service, label it Out of Service, and send for repair or bench evaluation by authorized personnel.
Clinical Use Tip
Do not attempt touchscreen troubleshooting on a patient actively being imaged. Move any patient to a backup device to maintain therapy continuity and patient safety.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Touchscreen intermittently fails to respond during exams; control panel buttons occasionally do not register input."
Cause
What was observed during troubleshooting.
Example:
"Touchscreen calibration was off, and control panel ribbon was slightly loose."
Resolution
What action was taken.
Example:
"Performed touchscreen calibration and reseated control panel connectors; system tested normal afterwards."
Helpful Details to Include (If Known)
- Touchscreen calibration results
- Control panel cable and connector status
- Software version and firmware updates applied
- Environmental factors affecting touch response
- Indicator lights or error messages
- Final device status after troubleshooting
Final Thought
Always ensure patient safety, rule out external factors, follow proper calibration and update procedures, and document all actions taken. Escalate to authorized repair when necessary.
That is successful troubleshooting.
