Troubleshooting

1. No Sound Output

• Check if you double-clicked the black side key on the remote control, which might have switched the projector to mute mode.
• Verify that the projector's "HDMI ARC" or Bluetooth interface is connected to an external audio device.

2. No Image Output

• Press the power button located on the back of the projector. If the projector successfully enters projection mode, the power button indicator light will turn off.
• Ensure the power adapter is receiving power.

3. No Network

• Go to Settings and check the network connection status in the network options.
• Ensure the network cable is properly connected to the projector's "LAN" interface.
• Ensure the router is configured correctly.

4. Blurry Image

• Adjust the focus or keystone correction.
• The projector and screen/wall must be placed at an effective distance.
• The projector lens is not clean.

5. Non-Rectangular Image

• If not using the keystone correction function, place the projector perpendicular to the projection surface/wall.
• Use the keystone correction function to adjust the display.

6. Automatic Keystone Correction Failed

• Ensure the camera/TOF on the front panel is not blocked or dirty. The optimal distance for automatic keystone correction is 2.0-4.0m, horizontally ±20-30°.

7. Autofocus Failure

• Ensure the camera/TOF on the front panel is not blocked or dirty. The optimal autofocus distance is 2.0-4.0m, horizontally ±20-30°.

8. Intelligent Eye Protection Failed

• Ensure the camera/TOF on the front panel is not blocked or dirty. The optimal sensing range is around the center of the image. Being too close to the edges may cause the eye protection function not to activate.

9. Intelligent Screen Fit Failure

• Ensure the projector is positioned correctly so that the projected image extends beyond the edges of the projection screen.
• Ensure the projection screen has a colored border on all four sides so the projector can recognize the frame.
• Ensure the red frame pattern is inside the screen frame and is not blocked.

10. Remote Control Unresponsive

• Ensure the remote control is successfully paired via Bluetooth. If pairing is successful, the LED indicator will blink once when you press any button. When you press and hold a button, the LED indicator will remain lit.
• If pairing fails, the LED indicator will blink three times when you press any button. When you press and hold a button, the LED indicator will blink three times and then remain lit.
• Check if the power indicator is still lit without pressing any buttons. If so, check the status of the remote control buttons to ensure they are not stuck.
• Ensure there is no interference or obstruction between the projector and the remote control.
• Check the battery and installation polarity.

11. Connect Bluetooth Device

Go to Settings, open [Remotes & Accessories], and pair other Bluetooth devices.
