What to do if the natus neoBLUE mini light does not appear when turned on?
- A
  agreeneAug 1, 2025
  If the light on your Natus Medical Equipment doesn't turn on, several issues could be the cause. First, ensure the AC outlet is working and the power switch is in the ON position. Check that the power cord is fully plugged into the device socket, and try a different power cord if necessary. If these steps don't work, the power cable or Current PCB might be damaged. Check the voltage at the end of the power cable (should be 12 ± 5%) and at specific points on the Current PCB (JP1). If the voltage is incorrect, consider replacing the power supply or the Current PCB. A damaged LED PCB may also be the reason, so replacing it might solve the problem.

  James WeaverAug 5, 2025
  If the light intensity on your Natus Medical Equipment won't adjust, the Current PCB might be damaged, or the Current PCB and LED PCB might not be connected properly. Try replacing the Current PCB and check the alignment of the JP1 and JP2 connectors. If the maximum adjustment limit has been reached, consider replacing the LED PCB.

  Jonathan HunterAug 10, 2025
  If multiple LED strings go out on your Natus Medical Equipment and you can't get the right intensity, it could be a damaged LED light panel or the maximum adjustment limit has been reached. Replace the LED light panel to resolve this issue.

Why is the lens of my natus Medical Equipment excessively hot?
- D
  Dr. Antonio MillerAug 14, 2025
  If the lens on your Natus Medical Equipment is getting too hot (above 50°C/122°F), it might be due to blocked air vents. Make sure the vents are clear. If the vents are clear, the main enclosure fan may not be running correctly. In this case, consider replacing the Current PCB.

How to fix natus Medical Equipment light that does not hold its position?

  Gwendolyn SwansonAug 18, 2025
  If the light on your Natus Medical Equipment isn't holding its position, check the arm bolts and tighten or loosen them as needed. If the light drifts, the gooseneck might have a memory preventing it from holding certain positions; try repositioning it or using the arm to achieve the desired location, ideally with the arm parallel to the light height.

What to do if the enclosure of my natus neoBLUE mini Medical Equipment bubbles or starts to deform?
- C
  castillodannyAug 22, 2025
  If the enclosure of your Natus Medical Equipment starts to bubble or deform, it's likely because the light is too close to a radiant heat source. Reposition the light to the side of the radiant warmer, no farther than 12 inches (30.5 cm) from the infant.

What to do if LED string(s) goes out on my natus neoBLUE mini Medical Equipment?
- C
  Carla FordAug 27, 2025
  If an LED string goes out on your Natus Medical Equipment, it could be due to an LED short or open. If the device still produces enough light, increasing the intensity may be enough, and there's no need to replace the panel. However, if the device doesn't produce enough light, you should replace the LED light panel.
