Why does my Xbox keep giving terrible green and purple pixelation when I start up games?

Hello Shano533! I'm Kris and I'd be happy to help you with your question.

Sorry to hear you are having issues? Which Xbox is this? Have you tried turning off HDR? Trying another HDMI cable or even testing on another TV?

My armor has maintained for a long while now. Keeping it that way to. Started with yellow and green but purple and red looked better to me.

Ok, so I was trying to fix a game that i was playing ( Call of duty black ops cold war) but when someone on the internet tried to help me I followed the exact instructions, cleared my Mac address but when my Xbox restarted it was green and purple. I Can go into any game, or to any settings and its still green and purple. is that enough information

I downloaded the update and everything went fine until the reboot. When it rebooted it kind of went into a green pixelated screen for a second then black and never started up. Then I restarted my XBOX it did the same thing. The second time I restarted
it started up normal, but I had to re-download the update again. I refuse to download until I find a solution.

and also now that i think about it on my inital startup it went from green screen to a crazy looking glitched out screen, like an old nintendo game all kind of colors and small pixels, for about 2 seconds and then black screen then an auto power down. starting
the second time was green screen freeze up.
