7. Troubleshooting
If you encounter issues, refer to the following common solutions:
- No Signal/Picture: Ensure all cables are securely connected. Verify the correct input source is selected on the projector.
- No Sound: Check the projector's volume settings and ensure any external audio devices are properly connected and powered on. Verify Bluetooth connection if using wireless audio.
- WiFi/Bluetooth Connectivity Issues: Restart the projector and your device. Ensure you are within range of the WiFi router or Bluetooth device.
- Blurred Image: Adjust the electric focus using the remote control (F+/F- buttons). Ensure the projection surface is flat.
- Image Distortion: The auto keystone correction should resolve most distortions. If not, check for manual keystone adjustment options in the settings.
- Streaming Service Limitations: Due to HDCP copyright restrictions, streaming services like Netflix and Disney+ may require a TV stick (sold separately) for playback. The projector itself does not bypass these restrictions.
- Projector Not Powering On: Ensure the power cord is firmly connected and the power outlet is functional. The projector is not battery-powered and must be plugged in during use.
