Troubleshooting

If you encounter issues with your Tecaki Mini Portable Projector X3, refer to the following common solutions:

No Image / Black Screen

• Power: Ensure the projector is properly connected to power and turned on.
• Source: Verify the correct input source (HDMI, USB) is selected on the projector.
• Cables: Check all cables (HDMI, USB) for secure connections. Try a different cable if possible.
• Streaming Apps: If using screen mirroring for apps like Netflix or Hulu, a black screen is expected due to HDCP content protection. Connect a streaming stick (Fire TV Stick, Roku) or a laptop via HDMI instead.

Blurry Image

• Focus: Adjust the manual focus ring on the projector until the image is sharp.
• Keystone: The projector has auto keystone correction. If the image is still skewed, ensure the projector is placed as directly as possible to the projection surface.
• Distance: Ensure the projector is within the recommended throw distance (3.2 to 16.4 feet).

No Audio / Poor Audio Quality

• Volume: Check the volume settings on both the projector and the connected device.
• Bluetooth: Ensure your Bluetooth audio device is properly paired and connected. If issues persist, unpair and re-pair the device.
• External Speakers: If using a 3.5mm audio cable, ensure it is securely connected to both the projector and the external speaker.
• Source Audio: Verify the audio is working on the source device (e.g., laptop, streaming stick).

Persistent White Speck in Image

• This may indicate a dust particle on the internal optics. While the included cleaning swabs are for the lens, internal dust may require professional servicing if it significantly impacts viewing.
