    What to do if light output measurement is out of specification for GE BiliSoft Medical Equipment?
    • D
      Diana LewisAug 20, 2025
      If the light output measurement of your GE Medical Equipment is out of specification, first, make sure the fiberoptic cable is fully inserted into the light box. Then, check the fiberoptic light pad and lenses for damage or discoloration. Ensure you're taking the irradiance measurement on a flat surface without any pad covers. Use a properly calibrated Ohmeda Medical BiliBlanket Meter II and perform a 6 or 9-point check. If the light output remains out of specification, remove the unit from service and seek assistance from service personnel.

    How to fix GE BiliSoft when the Unit Overheated Indicator light is on?
    • D
      David NortonAug 21, 2025
      If the Unit Overheated indicator light is on for your GE Medical Equipment, turn off the standby switch, disconnect the power cord, and wait up to 10 minutes for the thermal cutout switch to reset. Ensure the air filter and vents are unobstructed. After plugging the power cord back in and turning the standby switch on, verify that the fan is running. If the fan isn't running or the light turns on again, remove the unit from service and seek assistance from service personnel.

      Laura FrancisAug 25, 2025
      If your GE Medical Equipment shows no light output, ensure the fiberoptic cable is fully inserted into the light box. If it's not fully inserted, the LEDs will automatically shut off. If the standby switch is on (green LED lit) and there's still no light, remove the unit from service and seek assistance from trained service personnel. If the green LED isn't lit, check that the unit is plugged into a powered outlet.

    Why is the hour meter not working on my GE BiliSoft Medical Equipment?
    • K
      Kevin BooneAug 27, 2025
      If the hour meter on your GE Medical Equipment isn't working, first ensure the fiberoptic cable is fully inserted into the light box. The hour meter only runs when the fiberoptic light pad is illuminated. If the cable is fully inserted and it still doesn't work, remove the unit from service and seek assistance from service personnel.

    • D
      Derek HancockAug 28, 2025
      If the main unit cover, handle, or back plate of your GE Medical Equipment is cracked or damaged due to being dropped or impacted, remove the unit from service and seek assistance from service personnel. All damaged parts must be replaced, and the unit should be checked to ensure no internal damage has occurred.

    Why is the fiberoptic light pad connection too loose on my GE BiliSoft?
    • A
      angelmartinezAug 30, 2025
      If the fiberoptic light pad connection on your GE Medical Equipment is too loose, it may be due to the “breakaway” feature designed to protect the unit if the fiberoptic cable is pulled. If the fiberoptic cable has slack and the connector won't stay connected, remove the unit from service and seek assistance from trained service personnel.

    What does it mean when the LED failure indicator light is blinking on GE BiliSoft?
    • J
      jennifer17Aug 31, 2025
      If the LED failure indicator light is blinking on your GE Medical Equipment, it means at least one of the three LED pairs is not operating. The LED module needs to be replaced by service personnel. The system may still be used until the LED module is replaced, but the intensity will be lower than the specification.

    Why is the green indicator light off on my GE Medical Equipment standby switch?
    • K
      Kyle WareSep 7, 2025
      If the standby switch on your GE Medical Equipment is on but the green indicator light isn't lit, start by checking the power cord. Make sure it's in good condition and properly connected at both the light source and the power outlet. Then, check the fuses and replace them if necessary. Remove the cover and check the AC input to the Power Supply at connector J1. If there's no AC voltage present, replace the EMI filter or the AC harness as needed. Next, check the 12V DC output of the Power Supply at connector J3 (pins 1 and 4). If there's no output, replace the Power Supply. If there is output, replace the power supply harness or Control PCB as needed.

    What does it mean if the LED failure indicator light is blinking on my GE BiliSoft Medical Equipment?
    • A
      Amy MoralesSep 9, 2025
      If the LED failure indicator light is blinking on your GE Medical Equipment, remove the cover and check the connections on both the Control PCB and LED PCB. Check the voltage (typically 5V, but it can vary) at pin 1 on U2 on the Control PCB and ground on pin 4 on J2 on the Power Supply. Repeat this check on U8 and U11 on the main control board. If voltage is present at all three test points, replace the LED module. If voltage is not present, replace the Control PCB.
