If the 4K1 is unable to turn on

1. First 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 the brick specifically to ensure it is receiving power. The brick will have an LED that lights up when it is plugged in to indicate power is running through it.

4. If the projector shows no signs of power, then the power adapter may be defective and we can ship out a replacement one for you if you are under our one year warranty at no cost.

5. If you have done these steps and there is still no connectivity, please contact AAXA Technical Support either by email at info@aaxatech.com or by phone at (714) 957-1999 between 9AM and 4 PM PST for further assistance.
