Xbox one x problems

I got an xbox one x recently everything seemed to be running great until today , at first my screen started glitching out ( parts of it would turn green or purple ) and then it outright just stopped working ( all black screen ) , so i moved to another
tv and there were these little green dots popping up , and then I moved it to a monitor where everything seemed fine at first but every few seconds , the screen would shut off for like a second and then come back , then it stopped , i played for a bit and
left and turned it off , i come back and there’s nothing again , I moved to the first tv , and I would get small portions of it for a second and then all black again and it would keep repeating , I can only see the screen when it’s at 480p and it’s really
fuzzy with green dots and there’s multiple images of the same screen one on top of the other , i don’t know what to do if anyone has anything I can try please tell me

:)
