6. Troubleshooting
If you encounter issues with your DCOLOR U8 HDMI TV Stick, refer to the following common problems and solutions:

|---|---|---|
| Device displays "booting" continuously. | Insufficient power supply. Older TV USB ports (USB1) may only provide 500mA, while the receiver requires at least 1A. | Connect the receiver to a USB 5V wall adapter (e.g., a smartphone charger) that provides at least 1 Ampere. |
| No signal or "No Channel" message. | Antenna not connected, poor antenna signal, or incorrect input source on TV. | Ensure the antenna is securely connected. Check antenna positioning. Verify your TV is on the correct HDMI input. Perform a channel scan. |
| Channels disappear or cannot be found. | Signal fluctuations or an issue with the channel list. | Perform a new channel scan. If the issue persists, try a factory reset and then rescan. |
| Remote control not responding. | Batteries are dead or incorrectly inserted, IR sensor blocked, or remote not paired/programmed. | Replace batteries. Ensure the IR sensor has a clear line of sight to the remote. Check remote programming for TV control functions. |
| No audio or poor audio quality. | TV audio settings, incorrect audio output selected, or cable issue. | Check TV volume and mute settings. Ensure the correct audio output is selected on the receiver (if applicable). Verify HDMI cable connection. |
