If your Toshiba PSN-25AT is producing degraded images, failing probe tests or showing physical damage, this page helps you judge what is likely wrong and whether a repair makes sense before you commit to a replacement.
| Manufacturer | Toshiba |
|---|---|
| Model | PSN-25AT |
| Probe type | Phased Array |
| Compatible systems | Toshiba PowerVision 8000 (SSA-390A) |
You will usually see the PSN-25AT running on Toshiba PowerVision 8000 (SSA-390A). Mention the console model with the fault description – connector and revision differences matter.
Compact phased-array heads such as the PSN-25AT are sensitive to element dropout at the sector edges, and round-the-clock cardiac use is hard on cables and strain reliefs.
Common failure modes for the PSN-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? |
|---|---|---|
| Intermittent signal that changes as the cable moves | Broken internal conductors in the cable | Case by case |
| Air pockets or peeling visible on the acoustic lens | The lens separating from the acoustic stack underneath | Usually repairable |
| Grainy, low-detail image even after presets are checked | Lens wear or early element degradation | Case by case |
| Visible nicks, grooves or staining on the lens surface | Mechanical wear or disinfectant damage to the lens | Usually repairable |
| Strain relief pulling away from the cable or gone rigid | Flex fatigue where the cable meets the probe or connector | Usually repairable |
| Bent, broken or corroded connector pins | Connector damage from forced insertion or drops | Usually repairable |
| Cracked or dented housing | Impact damage; housing can usually be replaced or resealed | 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
- Compare penetration and uniformity against a known-good probe on the same preset.
- 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.
- Run the system’s built-in probe test or element check if your console provides one.
- Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
Repair, exchange or replace — which applies to your PSN-25AT
For the PSN-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 PSN-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
