Hi there! I understand your KY3 News app keeps shutting off on two different TV types, is that right? To help you better, could you please let me know the brands and models of the TVs you're using? Also, are you experiencing the app crashing right after opening it, or does it happen after some use? Any extra details will help me guide you through the best fix.

In the meantime, here are some general steps to try for smart TV apps crashing on multiple devices:

1. Restart Your TVs. Power them completely off, unplug from power for about 30 seconds, then plug back in and start them up fresh. This clears temporary glitches.

2. Check Your Internet Connection. Make sure your WiFi or wired Ethernet is stable. Sometimes switching between WiFi and a wired connection can help.

3. Update the KY3 News App. Go to your TVs’ app stores and see if there’s an update for the KY3 app. Running the latest version is important.

4. Clear the App Cache/Data. Depending on your TV, you can go into the settings for installed apps and clear the cache or data to refresh the app state.

5. Reinstall the App. Remove/uninstall the KY3 app from your TVs, then reinstall it from the official app store.

6. Update Your TVs’ System Software. Sometimes the TV’s firmware update fixes app compatibility.

If you’ve already tried some of these, let me know which ones and what happened. That way I can suggest more specific next steps based on your device type.

Let me know how it goes or if you want help with any particular step!
