What This Guide Helps With
Addresses unresponsive touchscreen or controls due to power, lock settings, external devices, or temporary system/software issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the system from active patient use before troubleshooting.
- If in use, transfer imaging to another ultrasound system.
- Why it matters: Prevents interruption of patient care and avoids delays during procedures.
Verify the Reported Issue
- Attempt to use both the touchscreen and any physical controls (trackball, buttons).
- Observe if:
- Entire screen is unresponsive
- Only certain areas do not respond
- Physical controls still work
- Expected: Confirm whether the issue is total or partial.
- Why it matters: Helps differentiate between touchscreen failure and broader system issues.
Check for Screen Lock or Software Freeze
- Look for any screen lock icons or inactive UI indicators.
- Attempt a soft reset by pressing the power button briefly (sleep/wake).
- Expected: Screen resumes normal responsiveness.
- Why it matters: Systems can appear frozen due to software lock states.
Perform a Full System Reboot
- Power down the system completely.
- Wait 30–60 seconds, then restart.
- Expected: Touchscreen and controls respond normally after reboot.
- Why it matters: Clears temporary software or UI processing errors.
Inspect for External Interference or Accessories
- Disconnect any external USB devices (keyboard, mouse, storage devices).
- Check for gel, fluid, or debris on the screen or control panel. Clean if needed per manufacturer guidelines.
- Expected: No obstruction or interference affecting input.
- Why it matters: External devices or contamination can interfere with touch input.
Check Power Stability
- Ensure the system is connected to a reliable power source or has adequate battery charge.
- Observe for any system lag, flickering, or instability.
- Expected: Stable power with normal system performance.
- Why it matters: Low voltage or unstable power can affect system responsiveness.
Test Control Panel Functionality
- Use alternate input methods (trackball, keyboard if available).
- Determine if only the touchscreen is affected.
- Expected: Other controls function normally if issue is isolated.
- Why it matters: Helps isolate touchscreen hardware vs full system failure.
Inspect for Physical Damage
- Check the touchscreen and control panel for cracks, impact damage, or signs of wear.
- Expected: No visible damage.
- Why it matters: Physical damage can cause loss of responsiveness.
If the Problem Persists
If all external and basic causes have been ruled out, the issue is likely internal (touchscreen digitizer, control board, or system software failure).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and aligns with proper Clinical Engineering practice.
Clinical Use Tip
Never troubleshoot an unresponsive ultrasound system while it is actively needed for patient imaging. Always move the patient to a functioning unit first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Touchscreen and control panel not responding during imaging use."
Cause
What was observed during troubleshooting.
Example:
"System software freeze causing loss of touchscreen input."
Resolution
What action was taken.
Example:
"Performed full system reboot; functionality restored and verified normal operation."
Helpful Details to Include (If Known)
- System powered on and rebooted
- Touchscreen vs physical control behavior
- External devices disconnected
- Screen condition (clean/damaged)
- Power source verified
- Any lag, freezing, or error messages
- Final device status (working or removed from service)
Final Thought
Effective troubleshooting starts with simple external checks and safe system resets before assuming failure. Maintaining patient safety, isolating the issue logically, and documenting clearly ensures reliable equipment support and proper escalation when needed.
That is successful troubleshooting.
