Xbox One X powers up for a few seconds and then turns off.

I bought a Xbox One X from a coworker knowing it was power surged from a storm. It was getting zero power. Replaced the internal power supply. Now it only beeps when you press the power button, or it will try and turn on for a few seconds and then turn off. Fan never cuts on. Motherboard looks fine as far as I can tell. I haven’t taken the heat sink off to look under it. When it turns on there is also no display. I’ve seen people post about this on multiple forms and sites, but I have not found a fix. I have tried multiple wall plugs and power cords also.
