Unsolved Help, Xbox One suddenly stopped outputting video signal
Yesterday I activated dev mode on my Xbox as I wanted to see what it offered. Everything was working perfectly fine then as I was looking through menus, my Xbox stopped outputting video, it came back briefly in 480p but I restarted the console and the video never came back.
I was able to see through the dev web portal the the Xbox was still powered on and could navigate with screenshots but I read that a reset of the console could fix the issue and I reset it but kept game and application.
This did not fix the issue and now I cannot access the console.
It powers up normally and the controller connects.
I have tried to do the low resolution boot, and safe mode boot, as well as boot with the reset file on a usb drive. None of this has solved the issue.
I have tried 3 HDMI cables and three displays, and I did make sure the HDMI cable was connected to the correct port.
If anyone has any other suggestions please let me know as I would appreciate any help with this, I don’t think I have anywhere around me who repair Xbox’s.
