AppleTV 4.2.1 Addresses ‘Flickering, Sound’ and Other Issues

Apple has quitely pused an update 4.2.1 to AppleTV. The Apple TV 4.2.1 addresses a couple of incredibly annoying bugs, which we’ve personally suffered from, including a flickering picture and a lack of audio when switching through sources on some TVs and AV receivers.

The update should also cure the problem of the Apple TV sleeping with the fishes and failing to wake up when commanded by the remote.

Apple also lists various ‘stability and performance fixes’ for the Apple TV, so with a bit of luck if you’ve got any outstanding issues from the previous update, they should be gone with 4.2.1.


Here’s a list of features:

  • TV compatibility
    Addresses issues that may cause the screen to flicker or display incorrect color on some older TVs.
  • Wake from sleep
    Addresses an issue where Apple TV may not wake up from sleep.
  • Audio
    Addresses an issue where audio may not be heard on some TV models after switching from another input.
  • Stability and performance
    Apple TV Software Update 4.2.1 includes stability and performance fixes for Apple TV.

The Apple TV 4.2.1 update can be downloaded either over-the-air on the Apple TV itself, or restored via iTunes.
