Series X - White Flash / Black Screen

it does the whole 360 loading screen where the green and white things go into the big X, but then the screen goes black

Let's troubleshoot:

- Unplug your console and power supply from power, leave it for five minutes.

- Try different HDMI inputs on your TV.

- Try different HDMI cables between the Xbox and TV.

- Try a different TV.

If it still flashes white after trying all of the steps above, you may have an internal issue with the console which will likely require it to be repaired by Microsoft. If this is the case, you can schedule a repair online with the console's serial number,
or contact Xbox Support (phone/chat) for more assistance.

I understand you’re having some trouble when trying to use your console with this TV. Let’s try to sort this out.

However, before that, I would like to ask the following questions:

Did you test the console on a different TV to verify if something similar happens?
Is your console enrolled in the Xbox Insider program?
Is this TV compatible with VRR, 120Hz, Dolby Vision, or similar features?
Is this happening with more games besides Call of Duty?

Has something happened to battlefield, as I was trying to play it tonight and I got dashboarded twice and when I get into a game it had reset all my weapons. So quit out and tried to get back in and just kept getting the black screen with the white icon
flashing in the top right of the screen.
