Controller will not pair to the console,via usb or wireless connection

Picked my series X up off marketplace. 1st mistake. Got home plugged it in. It powers up, displays an image, but I can’t get any controller to connect to it. When pressing the pairing button, the consoles logo does not blink, indicating it’s not attempting to pair. When I plug the controller into the usb port, it still doesn’t recognize it. Tried multiple controllers, and every usb port. It’s like all 3 ports are dead. No power. Tried plugging up a dongle to all 3 to see if it would light up. It did not.

Any advice on what to look for would be appreciated!
