Use the key combo below to switch resolutions until you find a valid one.
If your Apple TV doesn't turn on - Apple Support
If you see the Apple logo and then a black screen
If you see the Apple logo and then a black screen, hold Menu and Volume Down for five seconds, then release. Your Apple TV will switch to a new resolution every 20 seconds. Select OK to choose a resolution or Cancel to quit.
