Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Image dropout / dead element lines
HighSymptoms: Persistent dark vertical bands or a missing sector in the image that do not move with the anatomy.
Root cause: Failed piezoelectric elements in the array.
Intermittent image with cable flex
HighSymptoms: Image drops, flickers or is noisy when the cable or strain relief is moved.
Root cause: Broken conductors in the transducer cable or at the connector strain relief.
Acoustic lens / membrane damage
MediumSymptoms: Haze, comet artefacts, reduced penetration, visible cut or bubble under the lens.
Root cause: Lens delamination or a puncture letting fluid into the acoustic stack.
Connector pin damage / not recognised
MediumSymptoms: Scanner does not detect the probe or shows the wrong probe, bent or corroded connector pins.
Root cause: Damaged scanner-connector pins or a wet/dirty connector.
Housing seal leak (endocavity / biplane)
HighSymptoms: Fails a pre-use leak test, fluid ingress, erratic elements after reprocessing.
Root cause: Worn housing seal or a crack around the biplane array.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Dropout or dead lines in the image
- Confirm the artefact stays fixed on screen and is not shadowing from anatomy or gel bubbles.
- Clean the lens and re-gel; check for trapped air.
- Try the probe on a second compatible scanner, and a known-good probe on this scanner, to isolate probe vs system.
- Perform the pre-use electrical leak test.
- If the probe is confirmed faulty, return it to BK Medical for repair - do not open the housing.
Symptom: Image drops when the cable is moved
- Flex the cable along its length and at both ends while imaging a phantom.
- Inspect the connector pins for damage and the cable jacket for cuts.
- Confirm the connector is dry and fully latched.
- If the fault tracks the cable, return the probe to BK Medical.
- Have an electrical-safety test done after any repair before clinical use.
