Reset Apple TV
If you’re having problems and Apple TV still doesn’t respond after restarting, try resetting Apple TV to its factory settings. When you reset Apple TV, all data is erased, including your accounts and configuration.
You can also reset your Apple TV and update its software at the same time.
Reset Apple TV
Go to Settings
on Apple TV. Go to System > Reset, then select Reset.
Resetting Apple TV and restoring it to factory settings can take some time. If Apple TV still doesn’t respond, do one of the following:
If you have an Apple TV 4K: Contact Apple TV Support.
If you have an Apple TV HD and a Mac with macOS Catalina or later: Disconnect the HDMI cable from Apple TV, but leave the power connected. Connect one end of a USB-C cable (sold separately) to Apple TV and the other end to your Mac computer. Open the Finder on your Mac, select Apple TV in the sidebar, then select Restore. If that doesn’t work, contact Apple TV Support.
If you have an Apple TV HD and a PC with iTunes or a Mac with macOS Mojave or earlier: Disconnect the HDMI cable from Apple TV, but leave the power connected. Connect one end of a USB-C cable (sold separately) to Apple TV and the other end to your computer. Open iTunes on your computer, select Apple TV in the Source list, then select Restore. If that doesn’t work, contact Apple TV Support.
Reset Apple TV and update software
Go to Settings
on Apple TV. Go to System > Reset, then select Reset and Update.
Selecting this option restores your Apple TV to factory settings, erases all settings and information, and updates to the latest tvOS version.
You can use your iPhone or iPad to set up your Apple TV for faster recovery. See the Apple Support article If your TV shows an iPhone next to an Apple TV.
