Xbox 360 not turning on

I don’t know what happened but for some reason whenever I try to plug it in and turn it on, literally Nothing happens. Like there’s no rrod or lights the psu doesn’t even change there’s just nothing.

I’ve done some troubleshooting tips like

Unplug replug, Check for bad psu,

I’ve only used this a couple times.

Please if anyone knows how to fix this let me know.

:)
