There are a diode (D5) and a 47µF capacitor (C107) connected to the 5V line between the barrel connector for the power input and the power switch. If the diode or the capacitor is broken it may create a short between the power rail and ground right in front of the switch… so you’ll only see this short if the switch is in the ‘on’ position.

I would recommend: put the switch in the ‘off’ position and check if both pins of D5 or C107 are shorted. If they are: remove D5 first (because a broken diode is more likely) and check again after that.
