What This Guide Helps With

Troubleshooting a blank, frozen, dim, intermittent, distorted, or unresponsive touchscreen/display after external power, contamination, and startup causes are checked.

Step-by-Step Troubleshooting

Ensure Patient Safety First

Do not troubleshoot an unresolved touchscreen or display problem while the bladder scanner is being relied upon for active patient assessment.

If bladder-volume information is clinically needed, provide another verified bladder scanner or appropriate alternate assessment method before continuing.

Expected: Patient care is not delayed or dependent on a device with unreliable visual controls or results.

Why it matters: The BioCon 700 and 750 are bladder scanners, and available Medline product information identifies touchscreen display functionality as part of the device interface. An unreadable or unreliable interface can prevent dependable operation and interpretation.

If patient care is safely transferred, continue troubleshooting in a controlled Clinical Engineering setting.

Confirm the Exact Failure Behavior

Power on the unit and determine whether the problem is:

Expected: The complaint is narrowed to a display, touch-input, power-related, or intermittent condition.

Do not treat “screen broken” as a complete diagnosis.

Inspect for Physical Damage or Contamination

With the unit removed from patient use, inspect the display and surrounding enclosure for:

Clean the touchscreen only with facility-approved methods compatible with the equipment.

Expected: The screen is clean, dry, intact, and free of anything that could interfere with touch operation.

If cleaning restores reliable touch response, verify full operation and stop.

Remove External Touch Interference

Remove any non-original item that may be affecting the touchscreen, including:

Expected: The touchscreen responds normally without mechanical or surface interference.

If normal operation returns, document the cause and stop.

Verify External Power and Battery Condition

Check whether the failure occurs:

Inspect the external power adapter and accessible connections for looseness, damage, or intermittent contact. Medline lists power-adapter and battery accessories for the BioCon 700 and 750 family, supporting comparison of power-source behavior during troubleshooting.

When appropriate, test a known-good compatible power source or known-good battery according to facility procedure.

Expected: The display remains stable on a verified power source.

If the issue occurs only with one battery or external power accessory and a known-good compatible substitute resolves it, replace or route the failed accessory appropriately and stop.

Perform a Controlled Restart

If the display is frozen or touch input is unresponsive:

Expected: The unit boots normally and the touchscreen becomes responsive.

If the issue clears after restart, do not immediately assume permanent repair. Repeat operation sufficiently to determine whether the problem recurs.

Observe the Startup Sequence Carefully

During startup, determine whether:

Expected: The failure point helps distinguish a total display problem from touch-input failure, startup lockup, or broader system malfunction.

The BioCon 750 is described as having self-diagnostic capability, so any displayed hardware or maintenance indication should be recorded exactly rather than cleared and ignored.

Test Touch Response Across the Entire Active Screen

Using normal, non-destructive operation, test multiple accessible areas of the touchscreen.

Check whether:

Expected: Touch response is consistent across the usable interface.

A repeatable dead region, offset touch response, or phantom input strongly supports escalation rather than continued external troubleshooting.

Check for Temperature or Environmental Influence

Determine whether the complaint began after:

Allow the device to stabilize in the normal operating environment before retesting when appropriate.

Expected: The display and touchscreen operate consistently under normal environmental conditions.

If the issue resolves only temporarily and returns repeatedly, do not consider the device reliable.

Gently Check for Reproducible Intermittency

Without opening the enclosure or stressing the unit, observe whether the failure occurs during:

Do not strike, twist, flex, or intentionally shock the equipment.

Expected: The screen remains stable during normal handling.

If the display flickers, blanks, freezes, or changes during ordinary movement, remove the unit from service for bench evaluation.

Compare With Known-Good Compatible External Components

Where available and permitted, substitute only compatible known-good external items relevant to the observed condition, such as:

Medline lists accessories specifically for BioCon 700 and 750 scanners, so compatibility should be confirmed rather than assumed.

Expected: The failure either follows an external component or remains with the scanner.

If a known-good external component resolves the issue consistently, replace or route the failed component appropriately and stop.

Determine Whether the Failure Is Persistent or Intermittent

Repeat startup and normal interface checks enough to establish whether the issue is:

Expected: Clinical Engineering has a reproducible description of the failure before escalation.

Do not return the unit to service solely because an intermittent display fault temporarily disappeared.

Perform Final Functional Verification

If the issue appears resolved, verify normal device operation according to facility procedure and applicable manufacturer requirements.

Confirm:

Expected: The device demonstrates stable, repeatable operation.

If any display or touchscreen abnormality remains, stop troubleshooting and escalate.

If the Problem Persists

If the touchscreen remains blank, frozen, distorted, intermittently unstable, inaccurate, partially unresponsive, or unusable after external power, battery, contamination, environmental, restart, and compatible-accessory checks, common external causes have been ruled out.

The problem is likely associated with an internal display, touchscreen interface, internal connection, power distribution, processing, or other hardware/software condition requiring authorized evaluation. This is an engineering conclusion based on the external causes already excluded, not a board-level diagnosis.

The device should be:

Do not open the unit or begin internal display disassembly unless authorized, trained, and working from applicable service documentation.

Knowing when to stop is proper troubleshooting.

Clinical Use Tip

Do not troubleshoot an unreliable touchscreen or unreadable display while attempting to obtain clinically needed bladder-volume measurements.

Move the patient workflow to another verified device first. A scanner that powers on but cannot provide dependable visual control or result interpretation should not be treated as clinically ready.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported the BioCon 750 touchscreen intermittently froze and stopped responding during bladder scanning setup."

Cause

What was observed during troubleshooting.

Example:
"Inspection found heavy dried residue across the touchscreen surface; touch response returned normally after approved cleaning and remained stable during repeated functional checks."

Resolution

What action was taken.

Example:
"Cleaned the touchscreen using the approved method, restarted the scanner, verified touch response across the active display, and completed functional testing with no recurrence."

Helpful Details to Include (If Known)

Final Thought

Touchscreen and display problems should be approached logically: protect the patient first, confirm the exact behavior, eliminate surface contamination and power-related causes, test reproducibility, and escalate persistent faults appropriately. Clear CCR documentation preserves what was reported, what was actually found, and why the device was returned to service or removed for repair.

That is successful troubleshooting.
