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.
Poor 2D image quality across multiple probes
HighSymptoms: Noisy, low-contrast or non-uniform image, missing sector, drop-out that follows the system not the probe.
Root cause: Front-end / beamformer board fault, a probe-port (connector) board fault, or a system-board fault.
Transducer not recognised / probe-port fault
MediumSymptoms: A probe works on one port but not another, or is not detected at all.
Root cause: Worn probe-port connector or a scan-connector board fault.
Will not boot / intermittent shutdown
HighSymptoms: Dead system, hangs at boot, or powers off under load.
Root cause: Power supply / DC converter, the system battery, or a system-board fault.
Control panel / touchscreen or monitor fault
MediumSymptoms: Unresponsive TGC sliders or keys, distorted or blank display.
Root cause: Control-panel board, touchscreen, or the monitor.
Overheating / loud cooling fan
LowSymptoms: Thermal-shutdown warning, fan roar, hot exhaust.
Root cause: Failed or dust-clogged cooling fan or blocked air path.
DICOM / network / storage fault
LowSymptoms: Studies will not send to PACS, images will not archive, worklist empty.
Root cause: Network configuration or a storage-drive fault.

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: Poor image quality or a probe not recognised
- Try the probe on a second port and a known-good probe on the suspect port.
- Wipe off all gel, inspect the lens, and scan a phantom or your own forearm.
- Inspect the probe-port connectors for bent pins or debris.
- Run any built-in front-end / channel diagnostics.
- Replace the probe-port board or front-end board as isolated.
Symptom: Will not boot or shuts down
- Confirm mains and the on/off sequence per the manual.
- Check the power-supply / DC-converter outputs.
- Note any boot / POST beep or code.
- Reseat the system boards.
- Refer the power supply or system board as isolated.
