Hi there! I understand you're having trouble connecting the Newsmax app on your TV, and it says there's a problem with the source, while other options work correctly. Let’s troubleshoot this together.

First, could you let me know what kind of TV you’re using and whether you’ve already tried any specific troubleshooting steps? This will help me guide you better based on your situation.

In the meantime, here are some general steps you can try:

1. Check Internet Connection: Make sure that your TV is connected to the internet. You can verify this by trying to access another app.

2. Restart Your TV and Router: Turn off your TV and unplug it from the power source for about 60 seconds. While it’s off, unplug your router for a minute too. Then plug them both back in and turn them on.

3. Uninstall and Reinstall The Newsmax App: Sometimes the app itself may need a refresh. Consider uninstalling the Newsmax app from your TV and then reinstalling it from your app store.

4. Check for App Updates: Ensure that the Newsmax app is updated to the latest version. This can usually be done through your TV's settings or app store.

If the issue persists after trying these steps, please let me know any error messages you see or further details about your setup so that I can assist you better!
