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.
Low or uneven irradiance
HighSymptoms: Measured spectral irradiance below the target at the treatment plane, uneven across the field, slow bilirubin response.
Root cause: Blue LED array aging or partial failure, wrong treatment distance, or a dirty emitting surface.
LED array / driver failure
MediumSymptoms: Part or all of the array out, flicker, will not reach full output.
Root cause: Failed LED segment or the LED driver / power supply.
Timer / irradiance-meter fault
MediumSymptoms: Treatment timer or the built-in radiometer reads implausibly.
Root cause: Timer or radiometer sensor fault.
Height / arm positioning fault
LowSymptoms: The support arm will not hold the head at the set height.
Root cause: Worn arm friction / gas-assist.

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: Low or uneven irradiance
- Measure spectral irradiance with a calibrated blue-light radiometer at the treatment plane.
- Confirm the correct treatment distance and that the whole array is lit.
- Clean the emitting surface.
- Replace failed LED segments or the array if output is low.
- Re-measure and document irradiance.
Symptom: Array or driver failure
- Confirm mains power and the driver output.
- Isolate a dead LED segment vs whole-array failure.
- Replace the driver if the LEDs are unpowered.
- Replace the LED module for a failed segment.
- Verify full, even output and correct the timer.
