Answer to: My Xbox S starts to turn on and then shuts back offjust clean the filter or check the blades that rotate cause it causes over heating. if your going for no money spending option follow what I did. put the Xbox on, get a thin long stick and first locate the ventilation at the top of the Xbox remember your Xbox is on. start pushing the blades forcing it to spin a couple of times, when it starts spinning take the stick out and Walla it should start working. sometimes it spins automatically by itself when you do this like mine.
