How to fix the Xbox One 'black screen of death'
30 January 2019 Xbox One owners are reporting seeing a black screen after their console boots up, and issues saving games. It follows an Xbox Live issue, and Microsoft says it is currently attempting to fix “Xbox One console startup, title update, and sign-in errors.”
If this is what you're seeing right now, there's no need to panic: the problem is with the software and not your console. If you're unable to start up the console try unplugging it from the internet (if you're using an ethernet cable) to avoid connecting to Xbox Live. If you're using Wi-Fi, rest assured Microsoft is working on a fix.
If the black screen you're seeing is not related, we've outlined some tips on fixing the Xbox One Black Screen of Death.
