How do I get my Apple TV to work after not using it for awhile?

Hello ElizabethLStaub,

The Apple TV connects to your TV with an HDMI cable. So you need to select the correct input source with your TV,

for example: Source > HDMI 1, HDMI 2. Check your TV instructions for selecting the source.

Once you have the correct input selected on your TV you can configure the Apple TV
