7. Troubleshooting
7.1 Common Issues
- "No program!" message: This usually indicates an issue with the satellite signal. Check your LNB IN connection, antenna setup, and ensure you have performed a channel scan. Verify the satellite selection and transponder list are correct.
- No picture/sound: Check HDMI/SCART/AV connections to your TV. Ensure the TV input is set to the correct source.
- Network connection failure: For WiFi, double-check your network password. For Ethernet, ensure the cable is securely connected to both the receiver and your router. Restarting your router and receiver can often resolve temporary network issues.
- Remote control not working: Check the batteries in the remote control. Ensure there are no obstructions between the remote and the receiver's IR sensor.
8. User Tips

- Internet vs. Satellite: The receiver primarily uses a satellite antenna for TV channels. Internet connectivity (via Ethernet, built-in WiFi, or 3G USB dongle) is used for online features, firmware updates, and the GTShare app, not for receiving TV channels directly.
- Conditional Access: The device supports CA cards, which are used for accessing encrypted channels.
