Needing help with an Xbox Series X powering off a few seconds after power on.
Hi everyone! I am in need of some advice for a recent HDMI replacement I have been working on for a customers Series X, they had a damaged port and the replacement work went by without issues. However when reassembled (partially to make it easier to work with) it will power on, sit for between 3 to 5 seconds, then shut off. I tested for shorts on the HDMI pins and found no issues, along with that the board itself appears fine, no visible damage. Sources I have found say that if it shuts down in that time range that there is a short on the 12V rail, and probing the primary power connector does seem to show there is a short. The issue I'm running into is this is the first time I've ran into this issue and need to collect info to run on before proceeding. I'm running into issues understanding the schematics layout and over all just not having a cool time. attached will be some photos of the HDMI port, the encoder, and the (I believe) 3.3V step up.
