I am stuck on a menu in my Apple TV that has a computer and a settings icon. I can't get back to the main menu where all the APPS are!

Have you tried restarting? You have the icon for "computer" and it should be all the way down at the bottom under "general". That worked for me.

Sorry ... you have "computer" but "general" is in "settings".

Welcome to the Apple community.

Are you saying that you only have a computer and settings option on your main screen.

Does the remote control work.
