Use this reference to troubleshoot the Hitachi Aloka S31KP: identify the fault from what you see, judge whether it is typically repairable, and prepare the details needed for a quote.
| Manufacturer | Hitachi Aloka |

| Model | S31KP |
| Probe type | Linear array |
| Compatible systems | Hitachi Aloka Arietta Precision, Hitachi Aloka Arietta V60, Hitachi Aloka Arietta V70, Hitachi Noblus |
The S31KP typically pairs with Hitachi Aloka Arietta Precision, Hitachi Aloka Arietta V60, Hitachi Aloka Arietta V70, Hitachi Noblus; the same fault can present differently between console revisions, which is why the host system is asked for with the quote details.
Linear arrays like the S31KP 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 S31KP
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? |
|---|---|---|
| Latch or locking hardware damaged on the connector shell | Mechanical damage to the connector shell | Usually repairable |
| Visible nicks, grooves or staining on the lens surface | Wear from use, or chemical attack from disinfectants | Usually repairable |
| Strain relief pulling away from the cable or gone rigid | Cable flex fatigue at the probe or connector end | Usually repairable |
| Bent, broken or corroded connector pins | Connector damage from forced insertion or drops | 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 |
| Whole regions of the image blank across the array width | Widespread element or acoustic stack failure | Usually not economical |
| Vertical shadowing or missing scan lines on screen | Element dropout, or a conductor break inside the cable | Case by case |
Check these before you ship the probe
- Compare penetration and uniformity against a known-good probe on the same preset.
- Photograph the complete manufacturer label – the exact revision matters for parts compatibility.
- Examine the connector for bent or corroded pins, cracks and a working locking mechanism.
- 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 S31KP
Repair suits the S31KP when damage is mechanical or confined – lens membrane, strain relief, cable jacket, connector hardware. Once element dropout spreads across large sections of the array, repair cost climbs toward replacement value and stops making sense. If uptime is critical, ask about exchange options while your probe is assessed.
What we need to quote your S31KP 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
