8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No image displayed | Power not connected; Incorrect input source selected; HDMI/USB cable loose or faulty. | Verify the power cord is securely connected and the projector is powered on. Select the correct input source (HDMI, USB, etc.) from the projector's menu. Ensure all connection cables are firmly inserted and undamaged. |
| Image is blurry | Focus not adjusted correctly. | Use the electric focus button on the remote control to achieve a sharp image. Adjust until the text and images are clear. |
| Image is distorted (trapezoid shape) | Projector not aligned perpendicular to the screen. | The projector features auto keystone correction, which should automatically correct trapezoidal distortion. If distortion persists, ensure the projector is placed on a level surface and as directly in front of the screen as possible. |
| No sound or low volume | Projector volume too low or muted; External audio device not connected or improperly configured. | Increase the projector's volume using the remote control. Check if the projector is muted. If using external audio, ensure the Bluetooth device is paired correctly or the 3.5mm jack cable is fully inserted. |
| WiFi connection unstable or unable to connect | Signal interference; Projector too far from router; Incorrect password. | Ensure the projector is within effective range of your WiFi router. Try connecting to the 5GHz band if available for better stability. Double-check the WiFi password. Restart the projector and router if necessary. |
| Remote control not working | Batteries dead or incorrectly inserted; Obstruction between remote and projector. | Replace the AAA batteries in the remote control, ensuring correct polarity. Remove any objects obstructing the line of sight between the remote and the projector's IR receiver. |
| Screen mirroring not working | Devices not on the same WiFi network; Incorrect mirroring protocol selected; Device compatibility issues. | Confirm both your mobile device and the projector are connected to the same WiFi network. Ensure you have selected the correct mirroring option (iOS Cast/Android Cast) on the projector. Some streaming apps may restrict mirroring due to copyright protection. |
