- Publish content to individual players or groups of players.
- Remote Monitoring: Monitor the operational status, network connectivity, and playback status of your devices in real-time.
- Screen Control: Adjust brightness, power on/off, and perform other remote operations.
3.3 Local Content Update (USB)
For offline content updates or quick changes, you can use a USB drive:
- Format a USB drive to FAT32.
- Place your media files (videos, images) into a designated folder on the USB drive.
- Insert the USB drive into one of the USB-A ports on the TB20 Plus.

5. Troubleshooting
This section addresses common issues you might encounter with your NovaStar TB20 Plus.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply; power adapter faulty; power switch off. | Check power cable connection; ensure power adapter is working; verify power switch is ON. |
| LED screen shows no signal. | LED Out cable loose/faulty; display settings incorrect; no content scheduled. | Check LED Out cable connection; verify display parameters in NovaStar software; ensure content is published and scheduled. |
| Cannot connect to network (Wi-Fi/Ethernet). | Network cable disconnected; incorrect Wi-Fi password; network configuration issues. | Check Ethernet cable; re-enter Wi-Fi password; verify network settings in VNNOX or local configuration. |
| Content playback is choppy or freezes. | Unsupported video format; high-resolution content exceeding decoding capability; insufficient storage speed. | Ensure content meets supported specifications (e.g., H.264/H.265); optimize video resolution/bitrate; use a faster USB drive if applicable. |
| Cloud control not working. | No internet connection; device not bound to VNNOX; VNNOX server issues. | Verify internet connectivity; ensure device is correctly bound in VNNOX; check NovaStar service status. |
5.1 User Tips
- For optimal performance, ensure your network connection is stable and has sufficient bandwidth, especially when streaming high-resolution content or performing large content updates via the cloud.
- When using USB for content transfer, always safely eject the USB drive from your computer before removing it to prevent data corruption.
- Regularly back up your content and configurations, especially before performing major firmware updates.
- If experiencing persistent issues, try a soft reset (power cycle) first. If the problem continues, a factory reset might be necessary (consult NovaStar support for this procedure).
