Microsoft Xbox Series S 512 GB - Bianco (SOLO CONSOLE),

X box series S has no video output Before I took it apart to try to look at the hdmi port to see if I could replace it. The XBox would power on and just no video output. I took it apart but could not see anything wrong and the hdmi port is secured to the main board so I can't replace it . After putting it back together the Xbox turns on and turns right off . I looked it up and it says probably power supply problem but I'm guessing it's something I overlooked when putting it back together . I'm not sure what I'm doing . Was hoping for a easy fix . Just bought a new one. Comes with power cord
