Burn the over-voltage protection IC(NCP372) on XU4

When you short circuit the 5V and GND pins of the shift shield or expansion connector,
your odroid-xu4's over voltage protection IC can be blown up and there will be no red LED lighting.
the U5 and U6 are that. Reference - Schematics Page 2
You can easily solve this problem if you have a basic soldering skill.

1. Remove the heatsink. Check the protection IC U5/U6 surface. It seems to be fried.
   
   
   
2. Solder a wire from the 5V side of C37 to the 5V side of C38. these are the bypass capacitors of U6.
   
   
   
3. Remove the old thermal grease from the SOC and the heatsink. and Apply new thermal grease and attach the heatsink to the board.
