What This Guide Helps With

Troubleshoots cart, docking, or external display problems caused by power, cabling, seating, input selection, connections, or accessory configuration.

Step-by-Step Troubleshooting

1. Protect Patient Care

If the cart, dock, or external display failure interferes with safe visualization, mobility, power, or use during a procedure, move the patient workflow to another verified ultrasound configuration.

Do not troubleshoot unstable physical mounting or damaged cables while the system is being used for patient care.

Expected outcome: Clinical care continues without reliance on an unreliable accessory or display path.

2. Confirm Which External Component Is Affected

Determine whether the problem involves:

Expected outcome: The failure is isolated to the external monitor, cart, dock, cable, or system connection.

3. Inspect the Cart and Dock Physically

Inspect for:

Do not continue using a cart or dock that cannot safely support or secure the ultrasound system.

Expected outcome: The cart and dock are mechanically safe and visibly undamaged.

4. Verify External Power

If the cart, dock, or monitor requires AC power:

Expected outcome: Required accessory power is available. If restoring external power corrects the failure, proceed to final verification.

5. Reseat External Connections

With the system safely positioned, disconnect and reconnect accessible:

Do not force connectors.

Expected outcome: Connections are fully seated and communication is restored.

6. Confirm Proper Docking or System Seating

If the PX interfaces through a dock, verify it is fully positioned and latched according to normal operating use.

Check that no object or cable prevents complete seating.

Expected outcome: The system is mechanically and electrically engaged with the dock.

7. Verify External Monitor Power and Input

For an external monitor:

Expected outcome: The external monitor is powered, set to the correct input, and receives video from the PX.

8. Test a Known-Good Cable or Monitor When Available

Substitute an approved known-good external display cable or compatible monitor.

Do not change multiple components simultaneously if the failure can be isolated one item at a time.

Expected outcome: The problem follows the cable/monitor or remains with the PX/docking interface.

9. Compare Docked and Standalone Operation

If the system can safely operate independently of the dock, verify normal PX startup, imaging, controls, and display in standalone operation.

Expected outcome: The ultrasound system itself operates normally, helping isolate the issue to the cart or dock, or the problem persists regardless of docking.

10. Check for Movement-Related Intermittency

With no patient dependent on the system, observe the connection while the cart and cables are moved only through normal operating positions.

Do not flex or stress connectors deliberately.

Expected outcome: Communication remains stable. If normal movement causes repeatable loss of display or docking functions, remove the affected accessory configuration from service.

11. Perform a Controlled Restart

If all visible connections and accessory power are correct, restart the PX with the intended dock or display connection established as appropriate.

Expected outcome: External communication initializes normally and remains stable.

12. Perform Final Functional Verification

After correction:

Expected outcome: The PX, cart/dock, and external monitor configuration operate reliably together. Troubleshooting can stop after applicable safety and functional checks.

If the Problem Persists

If external power, physical condition, docking, cable seating, input selection, known-good substitution, and standalone operation have been checked, the remaining problem may involve internal docking electronics, video output, accessory communication, cart electronics, configuration, or another service-level fault.

The affected system or accessory should be:

Do not dismantle docking electronics, internal power assemblies, or system boards without authorized procedures.

After service, verify mechanical security, electrical safety as applicable, imaging, display, and all affected accessory functions before return to clinical use.

Knowing when to stop external troubleshooting and escalate is proper troubleshooting.

Clinical Use Tip

Verify both mechanical security and communication after docking; a system that appears seated but disconnects during normal cart movement should not remain in service.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported that the external monitor on the SonoSite PX cart intermittently lost the ultrasound image."

Cause

What was observed during troubleshooting.

Example:
"Clinical Engineering found the external video cable was loose at the monitor connection, while the PX display and imaging functions remained normal."

Resolution

What action was taken.

Example:
"Reseated and secured the external monitor connection, verified stable video during normal cart movement and imaging, and returned the system to service."

Helpful Details to Include (If Known)

Final Thought

Cart, dock, and external-display problems should be isolated through power, mechanical seating, cabling, and known-good comparisons before internal failure is assumed. Verify stability during normal use and document the complete correction.

That is successful troubleshooting.
