In service the D1914V-21228A-PENCIL is most often found on HP Sonos 4500, HP Sonos 5500, HP Sonos 7500. Console-side settings and module revisions still vary, so the exact system build is part of any assessment.
Pencil CW probes like the D1914V-21228A-PENCIL are mechanically simple but cable-dependent – most faults trace to the cable, connector or crystal rather than complex array electronics.
Common failure modes for the D1914V-21228A-PENCIL
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 | The lens separating from the acoustic stack underneath | Usually repairable |
| Strain relief separated, split or stiff | Flex fatigue where the cable meets the probe or connector | Usually repairable |
| Cuts, gouges or discoloration on the lens membrane | Mechanical wear or disinfectant damage to the lens | Usually repairable |
| Intermittent signal that changes as the cable moves | Broken internal conductors in the cable | Case by case |
| Cracked or dented housing | A drop or knock; housings are routinely replaced or resealed | Usually repairable |
| Cable jacket cracked, wrinkled or discolored | Jacket wear; conductors may still be intact underneath | Usually repairable |
| Bent, broken or corroded connector pins | Connector damage from forced insertion or drops | Usually repairable |
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.
- 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 D1914V-21228A-PENCIL
Three paths apply to a failing D1914V-21228A-PENCIL: 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 D1914V-21228A-PENCIL 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
Images shown are representative and are not photographs of an individual unit. Nothing on this page claims OEM authorization or guarantees universal fit. Whether a specific D1914V-21228A-PENCIL can be repaired, and on what terms, is confirmed in writing once the probe has been assessed.
