Apple TV 4K flashing white light and nothing else
Is there a way to reset the 4K Apple TV, it just keeps blinking white light, Nothing else,
Question marked as
First try to restart the Apple TV box, by temporarily disconnecting from power.
If that doesn’t improve things, then the system software needs to be re-installed, externally through a computer. Unfortunately, for the 4K models, users can’t do this themselves. Instead contact Apple Support for restoring service.
