1. Confirm that the adapter is plugged in normally, both ends of the charging cable are plugged in normally, and press the Power Button.

2. Confirm the status of the power indicator light (on the power button).

If the indicator light is not on and there is no response when you press the Power Button several times, you need to check whether the adapter and charging cable are normal; if you confirm that there is no abnormality in the adapter or charging cable, the probability is that it is a software and hardware problem, and you need to contact customer service to solve the problem.

If the light is red, continue to press the power button and the remote control's on button. If there is still no change, the probability is hardware and software problems, you need to contact customer service to solve.

If the red light is flashing fast, it means the adapter is not powerful enough, please use the original adapter and charging cable, or verify with another 140W adapter.

If the white light is on, but there is no image, then it is most likely a software or hardware issue and you need to contact customer service to solve it.

If the above solutions cannot solve your issue, please contact Nebula Customer Support at service@soundcore.com  for further assistance.
