I've got a PS5 HDMI repair in front of me. After installing 2 ports (largely on the assumption the first one was defective or whatever), I tested the pads themselves after removing the second HDMI port. Pads 15&16 are shorted together. I know that's not normal. Where do those go to, so I can further diagnose? They run to nearby vias and disappear. The system itself seems to fully boot, as the light turns white, but obviously not displaying anything. Any help would be greatly appreciated.
