If the power adapter or charging cable of Apollo has a problem, or there is a software issue, the projector might be unable to power on.I


To resolve this issue, please try the following steps:


  • Press the "power" button on the Apollo for 8 seconds to reset.
  • Make sure the power adapter is working well. If the power adapter works without issues, the Nebula Apollo's LED indicator will light up once it is plugged in.
