I found a shorted 5V roboRIO today and knocked on it really hard and the short went away. When I opened the roboRIO a thin copper wire was peeking out from under DIO 9. This wire had apparently found its way under the 3 pin header and shorted 5V to GND. Once I pulled the wire out the problem went away and roboRIO was happy again.

The controller has conformal coating so things that can be permanently damaged are protected from swarf (or random wires), but IO pins are exposed and while no lasting damage occurs, there can be a short condition that requires a little cleaning to clear up.... or a violent hit, especially if your robot's name is "tippy".
