My Google TV turns off while playing music via AirPlay from an iPhone

If your Google TV™ turns off while playing music via AirPlay®, this is due to the power-saving Turn-off when inactive setting.
To enhance your music listening experience and prolong your enjoyment, consider adjusting this specific setting. You can easily do this by following these simple steps:

1. On the TV remote control, press the Quick Settings button and select Settings.
2. Select System → Power and energy → Auto turn-off → Turn-off when inactive → Never. You can also choose to set it for a longer duration.

Note: For environmental reasons, the TV automatically turns off after a period of inactivity. This occurs because the TV doesn't recognize music playback as user activity.
