Hi there! I would love to help you get your Newsmax app working on your smart TV. To start, can you let me know which brand and model of TV you have? This will help me guide you through the proper troubleshooting steps.

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

1. Restart Your TV: Sometimes, a simple restart can resolve issues. Just power off your TV, wait for a moment, and then turn it back on.

2. Restart Your Router: Network problems can also affect app performance. Restart your router by unplugging it for about 30 seconds before plugging it back in.

3. Check for Updates: Make sure your TV’s software and the Newsmax app are both up to date. You can usually check for updates in your TV's settings menu under "Software Update."

4. Uninstall and Reinstall the App: If the app is still not working, you might want to uninstall it and then reinstall it from your TV's app store.

5. Sign Out and Back In: If you're logged into the app, try signing out and then signing back in to see if that restores functionality.

Let me know which steps you've tried or any additional details about your TV, and we can get to the bottom of this!
