That is because your monitor is sucking power from the PTC and causing it to get hot. That is what it is there for. The PTC connects 5V to the HDMI connector. It connects to nothing else on the board. I suspect the short may be in the cable or you monitor.
Try another monitor and see if you have the same issue.
