7. Troubleshooting
If you encounter issues with your projector, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No picture | Loose cable connection, incorrect input source, projector off. | Check all cable connections. Select the correct input source. Ensure the projector is powered on. |
| Blurry image | Out of focus, incorrect projection distance. | Adjust the focus ring. Ensure the projector is within the recommended projection distance. |
| No sound | Volume too low, external audio device not connected, incorrect audio settings. | Increase volume. Check external audio device connection or Bluetooth pairing. Verify audio output settings. |
