The Philips 21365A is a common candidate for repair rather than replacement. This page lists its typical failure modes, self-checks you can run, and the details a repair lab needs from you.
| Manufacturer | Philips |
|---|---|
| Model | 21365A |
| Probe type | TEE array |
| Compatible systems | HP Sonos 2000, HP Sonos 2500 |
The 21365A 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 21365A, 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 21365A
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? |
|---|---|---|
| Grainy, low-detail image even after presets are checked | A worn lens surface or elements beginning to degrade | Case by case |
| Connector lock broken or hardware missing | Broken locking mechanics on the connector housing | Usually repairable |
| Large areas of the array not firing | Extensive element loss across the acoustic stack | Usually not economical |
| Split seams or impact marks on the probe body | A drop or knock; housings are routinely replaced or resealed | Usually repairable |
| Strain relief separated, split or stiff | Cable flex fatigue at the probe or connector end | Usually repairable |
| Intermittent signal that changes as the cable moves | Broken internal conductors in the cable | Case by case |
| Bubbles or lifting at the lens face | Lens delamination from the acoustic stack | 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
- 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.
- Run the system’s built-in probe test or element check if your console provides one.
- 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 21365A
For the 21365A, 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 21365A 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

Repair feasibility, turnaround and commercial terms are confirmed in writing after assessment of the actual probe.
