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.
Will not power on or unexpected shutdown
HighSymptoms: The medical imaging is dead, reboots, or shuts down mid-use.
Root cause: Mains lead / fuse, an aged battery, or a power-supply board fault.
Battery will not hold charge
MediumSymptoms: Short run time on battery; low-battery alarm soon after a full charge.
Root cause: Aged rechargeable battery pack or a charger fault.
Display / control-panel fault
MediumSymptoms: Blank, dim or distorted display; unresponsive keys or touchscreen.
Root cause: Display, backlight, or control-board fault.
Fails self-test or calibration
MediumSymptoms: Power-on self-test or the scheduled performance check fails or is out of tolerance.
Root cause: Sensor drift or an internal board fault; recalibration or repair needed.

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: Image artefacts / poor fluoro or CT image / failed calibration
- Run the daily air / water (fast) calibration; if it fails, run the full calibration set.
- Scan / image a uniform phantom and review uniformity and noise against baseline.
- Check the X-ray tube warm-up and heat-unit / arc status.
- Check the detector / image-intensifier / flat-panel performance via service diagnostics.
- Escalate a confirmed detector-channel, DAS or tube fault to the OEM; re-verify with the phantom after any correction.
Symptom: Exposure aborts / tube-arc errors / kV-mAs fault
- Record the exact error codes and the phase (warm-up vs scan / fluoro vs cine).
- Run extended tube conditioning / seasoning.
- Review the arc-count and heat-unit trend.
- Confirm the chiller / heat-exchanger operates and coolant is at level.
- Plan a tube replacement when arc counts climb or output drifts; verify output after any HV work.
Symptom: Gantry rotation / slip-ring / positioner fault
- Note the axis and any collision-sensor indication.
- Clear obstructions and check the body-contour / collision sensors.
- Inspect the slip-ring brushes (dust, wear) and the drive belt / bearings.
- Run the motion self-test / calibration.
- Replace the brush set / drive component or refer as isolated.
Symptom: Table / cradle drifts, will not index or reach position
- Note the position / geometry error.
- Check for a mechanical obstruction on the table.
- Run the table drive self-test / calibration.
- Inspect the drive, brake and encoder.
- Replace the drive component or refer as isolated.
Symptom: Reconstruction / console / PACS fault
- Note the console / recon error.
- Restart the recon hardware / console per the OEM procedure.
- Check free storage and the database.
- Confirm the network link to PACS.
- Escalate a recon-hardware or host fault to the OEM.
