8.3.4 Image Errors
88..33..44..11 The probe can be recognized but no echo signal is detected in the
ultrasound image region.
Fault Description
The probe can be recognized but no echo signal is detected in the ultrasound image region.
Involved FRU
Probe and Main Board Assembly
Severity
Suspension
Handling Level
Contact the device provider for onsite handling.
Possible Cause
1. The probe is faulty.
2. The main board is faulty.
Resolve Path
1. Cross-test multiple probes. Connect each probe to the main unit in sequence and check
whether no image displays in the echo region of a single probe or echo regions of multiple
probes.
2. If only one probe is faulty, the failure is caused by the probe fault.
3. If no image is displayed for all probes, listen and check whether the probe head makes
transmission sound in the freezing state. If so, the frontend receiving part is abnormal and the
main board is faulty. Self-test can further determine the fault source.
