This page covers the Toshiba PLQ-703A 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 | PLQ-703A |
| Probe type | Linear array |
| Compatible systems | Toshiba Famio 8 (SSA-530A) |
In service the PLQ-703A is most often found on Toshiba Famio 8 (SSA-530A). Console-side settings and module revisions still vary, so the exact system build is part of any assessment.
Linear arrays like the PLQ-703A concentrate wear at the lens edges and the cable exit – shallow, high-frequency work means constant handling, and the first faults are usually mechanical rather than acoustic.
Common failure modes for the PLQ-703A
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? |
|---|---|---|
| Depth performance clearly below what this probe used to deliver | Ageing elements or lens delamination reducing acoustic output | Case by case |
| Cracked or dented housing | Impact damage; housing can usually be replaced or resealed | Usually repairable |
| Connector lock broken or hardware missing | Mechanical damage to the connector shell | Usually repairable |
| Whole regions of the image blank across the array width | Widespread element or acoustic stack failure | Usually not economical |
| Dark bands or dropout lines in the image | Failed transducer elements or a broken conductor in the cable | Case by case |
| Outer cable sheath showing cracks, kinks or staining | Surface jacket wear – the conductors inside are often still good | Usually repairable |
| Image cuts out when the cable is flexed | One or more conductors broken inside the cable bundle | Case by case |
Check these before you ship the probe
- Compare penetration and uniformity against a known-good probe on the same preset.
- 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.
- 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 PLQ-703A
Three paths apply to a failing PLQ-703A: 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 PLQ-703A 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
