Before writing off a damaged HP 21363A, compare its symptoms against the failure modes below. Many lens, cable and connector faults on this probe class are economically repairable.
| Manufacturer | HP |
|---|---|
| Model | 21363A |
| Probe type | TEE array |
| Compatible systems | HP Sonos 2000, HP Sonos 2500 |
The 21363A typically pairs with HP Sonos 2000, HP Sonos 2500; the same fault can present differently between console revisions, which is why the host system is asked for with the quote details.
On TEE heads such as the 21363A, articulation cables, tube integrity and bite damage dominate the fault picture; electrical leak testing is non-negotiable after any suspected breach.
Common failure modes for the 21363A
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? |
|---|---|---|
| Bubbles or lifting at the lens face | Lens delamination from the acoustic stack | Usually repairable |
| Image cuts out when the cable is flexed | One or more conductors broken inside the cable bundle | Case by case |
| Grainy, low-detail image even after presets are checked | A worn lens surface or elements beginning to degrade | Case by case |
| Cable jacket cracked, wrinkled or discolored | Jacket wear; conductors may still be intact underneath | Usually repairable |
| Whole regions of the image blank across the array width | Widespread element or acoustic stack failure | Usually not economical |
| Cracked or dented housing | A drop or knock; housings are routinely replaced or resealed | Usually repairable |
| Pin damage or corrosion visible in the connector | Mechanical damage from forcing or dropping the connector | Usually repairable |
| Bite marks or punctures on the insertion tube | Patient bite damage to the flexible shaft | Case by case |
| Tip articulation stiff, loose or unresponsive | Worn or broken articulation cables | Case by case |
| Failed leak test on a TEE probe | Breach in the insertion tube or tip sealing | 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.
- 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.
- Check the strain reliefs at both ends for splits, stiffness or separation from the cable.
- Do not continue clinical use after suspected bite damage; note the articulation behaviour (stiff, loose, unresponsive) for the assessment.
Repair, exchange or replace — which applies to your 21363A
Repair suits the 21363A 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 21363A 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
