Black screen on Apple TV 4K
At startup I see a black screen. Replaced cable, the tv, and the Apple TV. Software yo to date. Startup order doesn’t matter, nothing works. Is there a fix?
Apple TV 4K, tvOS 16
Try cycling the video settings using the remote button combination, until you find a valid one, as described in: If your Apple TV doesn't turn on - Apple Support (second bullet point).
Also: Is the status light glowing continuously?
