When the Apple TV needs a complete reset to factory settings, there is usually a problem with tvOS that does not get resolved by a simple reboot. The process of resetting the Apple TV will update the unit to the latest firmware version and remove data such as account passwords and user preferences.
If the light on your Apple TV blinks for three minutes straight or the unit does not work properly after a reboot, it might need to be restored to factory settings. Here are instructions on how to restore the Apple TV firmware with iTunes and a computer.
There is no power button on the Apple TV, however rebooting the device is simple. If the Apple TV menu is visible, the Apple TV can be restarted using the following instructions:
On the Apple TV, navigate to Settings -> General -> Restart.
The Apple TV can be paired with one remote control, however doing so makes other remotes unrecognizable to the Apple TV. To use multiple remotes (two or more) with one Apple TV console, the unit must be unpaired with one remote. To unpair an existing remote follow these steps:
On the Apple TV navigate to Settings -> General -> Remotes -> Unpair Apple Remote.
The three-year old Apple TV has finally been refreshed. Apple detailed the next generation Apple TV at its fall media event. Highlights include a brand new remote control, which adds touch controls and Siri integration to the experience. The top surface of the remote is designed with a glass surface for easy swiping and touch selection. Siri brings voice search to the device, spanning multiple content sources such as Netflix and Hulu and returning all relevant watching options in one place.
