Troubleshooting tvOS Updates

Usually, updating tvOS software on Apple TV is a smooth process, but sometimes there can be issues. Sometimes it’s the software update itself that might cause new problems. It’s best to wait for a while before updating to the latest version of tvOS.

Also, when updating, make sure that you have a stable Wi-Fi connection, and that you don’t unplug your Apple TV during the installation process. 

White Screen Issue

If your Apple TV is showing a white screen with a white cord and the iTunes icon, it means that your Apple TV needs to be restored using iTunes.

Restore Bricked Apple TV

If your Apple TV is bricked and it won’t turn on, the only thing you can do is to restore it from iTunes. 

1. To do this, you’ll first need to connect your Apple TV to your computer.

3. Then open the iTunes app on your Mac or PC. If you’re using macOS Catalina, open the Finder app instead. 
4. Then select your device from the sidebar and choose the Restore Apple TV button to start the restore process.
