Toshiba PVK-357AT Ultrasound Probe Repair

This page covers the Toshiba PVK-357AT from a repair perspective: the failure modes we see on this class of probe, how to check the probe yourself, and what information gets you an accurate repair quote.

Manufacturer	Toshiba
Model	PVK-357AT
Probe type	Convex array
Compatible systems	Toshiba PowerVision 7000 (SSA-380A)

You will usually see the PVK-357AT running on Toshiba PowerVision 7000 (SSA-380A). Mention the console model with the fault description – connector and revision differences matter.

On convex probes such as the PVK-357AT, the curved acoustic window wears unevenly under pressure-heavy scanning; lens condition is the first thing to check when image quality drops.

Common failure modes for the PVK-357AT

Match what you are seeing against the table below. The right-hand column reflects how faults of this kind typically assess – the actual verdict always depends on the individual probe.

What you see	Likely cause	Typically repairable?
Strain relief separated, split or stiff	Flex fatigue where the cable meets the probe or connector	Usually repairable
Visible nicks, grooves or staining on the lens surface	Wear from use, or chemical attack from disinfectants	Usually repairable
Bent, broken or corroded connector pins	Mechanical damage from forcing or dropping the connector	Usually repairable
Large areas of the array not firing	Widespread element or acoustic stack failure	Usually not economical
Cable jacket cracked, wrinkled or discolored	Surface jacket wear – the conductors inside are often still good	Usually repairable
Connector lock broken or hardware missing	Mechanical damage to the connector shell	Usually repairable
Bubbles or lifting at the lens face	The lens separating from the acoustic stack underneath	Usually repairable

Check these before you ship the probe

• Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
• Flex the cable gently along its length while imaging – intermittent dropout points to broken conductors.
• Photograph the complete manufacturer label – the exact revision matters for parts compatibility.
• Run the system’s built-in probe test or element check if your console provides one.
• Examine the connector for bent or corroded pins, cracks and a working locking mechanism.

Repair, exchange or replace — which applies to your PVK-357AT

Three paths apply to a failing PVK-357AT: repair (typical for lens, housing, cable and connector damage), exchange (fastest route back to scanning) or replacement (when the acoustic stack is too far gone). The deciding factors are how much of the array still fires, whether the housing is intact and what downtime costs you. Each probe is judged on its actual condition.

What we need to quote your PVK-357AT repair

• A clear photo of the complete manufacturer and model label on the probe
• A description of the fault: what you see on screen and when it started
• The ultrasound system (console) the probe is used with
• Screenshots or photos of the image problem, if the fault is visual
• Photos of any physical damage – lens, housing, cable or connector

Images shown are representative and are not photographs of an individual unit. Nothing on this page claims OEM authorization or guarantees universal fit. Whether a specific PVK-357AT can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
