The projector has two systems. When you are in the projector system, you are controlling the volume of the projector system, so as in the Android system. When you think the sound is lower than before, please switch to the other system to check the volume.

Please ensure that you have adjusted the sound on your device and two systems of the projector(projector system & Android TV system).


The ventilation of the projector might be blocked. Move the stuff away and turns off the projector for half an hour to cool it down. Make sure that nothing is blocking the ventilation when you turn on the projector again.

The screen shows no signal. You might choose HDMI or USB accidentally.

  • Go to the projector system again with the switch button on the remote control.
  • Or press the home page button to switch the signal source.


  1. The Wi-Fi connection might be unstable. Please check your home Wi-Fi speed first. If other devices have the same case, try to reboot your Wi-Fi router.
  2. Too many devices connect to the same Wi-Fi, which might lead to slow Internet. Please disconnect other devices from the same Wi-Fi and try to play the video again.
  3. If your Wi-Fi speed is slow, you can change the resolution of the video to a lower one for a faster watching experience.
  4. Try to cast videos to the projector, not to mirror your devices to the projector. Mirror takes more traffic from the Internet than cast.

Audio latency is the time it takes for audio move from your projector to your Bluetooth speaker. And Bluetooth connection spend a lot more time in the "processing" stage than a traditional wired connection. Plus, Bluetooth connection will be interfered by another signal source such as WiFi. There are some solutions below that you could decrease the latency:

  1. Disconnect other devices from your soundbar. As other devices might try to connect with it and influence the connection to the projector.
  2. Turn off other wireless connections close to the projector and Bluetooth signal.
  3. Keep your distance from other Bluetooth devices to avoid interference.
  4. Change the position or location of your device. It may need to be closer to the video.
  5. Disconnect other Bluetooth devices with the projector, as too much Bluetooth devices connected will interfere the Bluetooth signal.
  6. Feel free to contact usif the problem still exist.

Please follow these steps to fix the problem.

  1. Disconnect other devices from your Bluetooth devices.
  2. Restart the Bluetooth device and projector.
  3. Keep your Bluetooth speaker close to the projector.
  4. If the Bluetooth speaker is powered on by a battery, ensure it's not in an out-of-power state soon. A low battery state will influence the performance of the Bluetooth connection.
