AAXA P400 projector is a new projector from the AAXA brand. If you find the projector can’t turn on suddenly, you can check the following solutions for troubleshooting.
1. Check the power adapter is working by ensuring it is securely plugged in where the cord goes into the brick and where the plug goes into the outlet. Try testing with other power outlets to see if the power adapter is working correctly.
2. Try to turn the projector on via the On/Off switch on the back of the projector and see if the fans start to go and it starts to boot up.
3. Check whether the projector is overheating. You can try to turn it on later when it cools.
4. If the AAXA P400 projector shows no signs of power, then the power adapter may be defective. You can ship it back if you are under the one-year warranty.
