Troubleshooting your series X HDMI port:
1. make sure you are using a 4k TV. as some consoles are set to 4k only and you wont see anything.
2. make sure your port is clean by using 91% or higher isopropyl alcohol. dab the HDMI cable and insert in a few times! that should clear out the dirt.
3. physically inspect the port to look for loose wires, golden misaligned pins or any physical damage.
