Troubleshooting Novastar TB2: Resolving the Black Screen Issue

In the world of LED signage, occasional technical hiccups can arise, even with reliable hardware like the Novastar TB2. A common issue reported by users is the screen going black while still maintaining communication with the sign. After some investigation, we discovered that this problem often stems from the card inadvertently switching to HDMI mode, even when no HDMI input is connected. Below, we provide a real-world case, the solution, and confirmation that this fix works effectively.

Understanding the Problem: One of our customers, Robert, recently experienced this issue. His LED sign's screen went black unexpectedly, yet he could still communicate with the sign. After troubleshooting, we identified that the Novastar TB2 card had switched to HDMI mode, causing the screen to display a blank output due to the lack of an HDMI input.

Solution: If you encounter a similar issue with your Novastar TB2, follow these simple steps to resolve it:

1. Access Terminal Control:

   • Connect to your sign as usual.
   • Navigate to the Terminal Control section within the software interface.

2. Check Video Source Settings:

   • Locate the option for Video Input or Video Source.
   • Ensure that the video source is set to Internal rather than HDMI.

3. Apply and Verify:

   • Save your settings or apply the changes.
   • Confirm that your sign is now displaying content correctly.

Real-World Case: Robert implemented these steps on his sign, and it immediately resolved the issue. His screen returned to normal operation, and no further problems were reported. This solution is straightforward and can be easily executed without the need for extensive technical knowledge.

Conclusion: By following these troubleshooting steps, you can quickly fix the black screen issue caused by the Novastar TB2 card switching to HDMI mode. Always ensure your video source is set correctly to avoid similar disruptions in the future.
