Q: Can't find apple TV in iTunes

Hello BrianandNancy,

It sounds like you are unable to airplay to your Apple TV because you cannot see the Airplay icon in the iTunes application. I would recommend using the troubleshooting in the following article to help troubleshoot the issue:

iTunes: Troubleshooting AirPlay and AirPlay Mirroring

These steps in particular:

Try these steps first:

1. Verify that you are using the latest version of iTunes.
   • iTunes for Mac: Choose iTunes > Check for Updates
 
   • iTunes for Windows: Choose Help > Check for Updates
2. Verify that all your AirPlay-enabled devices' software is up to date. 
3. Verify that all your AirPlay-enabled devices are connected to the same home network.
   Note: Some Wi-Fi network configurations offer a guest network that can block certain Internet services from working or seeing other devices on your home network. 

If the AirPlay icon doesn’t appear in iTunes

Ensure that you followed these steps to use AirPlay in iTunes.

If the AirPlay icon  still doesn't appear, try one of the following steps:

 

• If you want to AirPlay to an Apple TV, ensure that AirPlay is enabled on the Apple TV.  From the Apple TV main menu, go to Settings > AirPlay. This should be set to On.
• If you want to AirPlay to an Airport Express, ensure that AirPlay is enabled in the device settings.
• If you want to AirPlay to a 3rd party AirPlay-enabled device, refer to the user guide.

Thank you for using Apple Support Communities.

All the very best,
