Toshiba PST-25AT Ultrasound Probe Repair

This page covers the Toshiba PST-25AT 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	PST-25AT
Probe type	Phased Array
Compatible systems	Toshiba Aplio 50 (SSA-700A)

The PST-25AT typically pairs with Toshiba Aplio 50 (SSA-700A); the same fault can present differently between console revisions, which is why the host system is asked for with the quote details.

Phased arrays like the PST-25AT pack tightly spaced elements into a small footprint – edge-element failures distort the sector image early, and cardiac duty cycles accelerate cable fatigue.

Common failure modes for the PST-25AT

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?
Outer cable sheath showing cracks, kinks or staining	Jacket wear; conductors may still be intact underneath	Usually repairable
Depth performance clearly below what this probe used to deliver	Reduced acoustic output from element ageing or a delaminating lens	Case by case
Vertical shadowing or missing scan lines on screen	Failed transducer elements or a broken conductor in the cable	Case by case
Split seams or impact marks on the probe body	Impact damage; housing can usually be replaced or resealed	Usually repairable
Image cuts out when the cable is flexed	Broken internal conductors in the cable	Case by case
Bent, broken or corroded connector pins	Connector damage from forced insertion or drops	Usually repairable
Bubbles or lifting at the lens face	The lens separating from the acoustic stack underneath	Usually repairable
Sector image narrows or loses the apex	Element failure concentrated at the array edge	Case by case

Check these before you ship the probe

• Run the system’s built-in probe test or element check if your console provides one.
• Inspect the lens face under good light for cuts, bubbles, lifting edges or discoloration.
• Photograph the complete manufacturer label – the exact revision matters for parts compatibility.
• Flex the cable gently along its length while imaging – intermittent dropout points to broken conductors.
• Check the strain reliefs at both ends for splits, stiffness or separation from the cable.

Repair, exchange or replace — which applies to your PST-25AT

For the PST-25AT, think in terms of damage depth: surface and cable-level faults are usually repairable at a fraction of replacement cost; acoustic stack failures are evaluated case by case; extensive element loss generally means replacement. Send the symptoms and photos first – that determines the path before anything ships.

What we need to quote your PST-25AT 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 PST-25AT can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
