Apple TV 4K frozen and not responding to any remote.

Hi florentin77,

If the Apple TV remote is not responding, follow the guide at If your Siri Remote or Apple TV Remote isn't working:

"If your remote isn't working as expected, learn what to do.

Try these steps first

1. Stay within 20 feet (about 6 meters) of your Apple TV and move anything that blocks the path between your remote and the front of your Apple TV, television, receiver, and sound bar.
2. Charge your remote for 30 minutes using a USB-C to USB or Lightning to USB cable and a USB wall charger."

then if still not responding:

1. "Press and hold the TV/Control Center button  and the Volume Down button  at the same time. Hold the buttons down for about 5 seconds, or until the status light on your Apple TV turns off and on again.  
2. Release the buttons. Then wait 5 to 10 seconds for a Connection Lost notification to appear on your TV screen.
3. Wait while your remote restarts. When the Connected notification appears, you can use your remote."

You may also need to use these steps to pair the remote if that connection was lost:

"If your remote still isn't working as expected, try pairing your remote to your Apple TV again. 

1. Point your remote at your Apple TV. Make sure that the remote is about three inches from your Apple TV. 
2. Press and hold Back  (or Menu) and Volume Up  for five seconds.
3. If asked, place your remote on top of Apple TV to complete pairing."

Failing all of those, use the directions in the reply above to contact Apple directly to investigate further.

Regards.

Hi florentin77,

Thanks for posting in Apple Support Communities! Since your Apple TV seems to be stuck during setup, follow the guidance below from the article Set up your Apple TV to get your device working again:

"If your Apple TV stops responding during setup, unplug your Apple TV from power, then plug it back in.

If you can't get past a screen during setup, try connecting your Apple TV to a different Wi-Fi network, like a personal hotspot from your phone. After setup is complete, go to Settings on your Apple TV and connect to your home Wi-Fi network."

If the behavior continues, contact Apple Support.

Cheers!
