You're not supposed to be supplying power on either the 3.3V or the 5V pins (although, there's no damage in doing so). Power should be supplied between Vin and GND through the pins or the JST connector. If everything is valid, you should be able to measure 5V and 3.3V on the respective pins (relative to GND). If you can't get 5V output in this case, chances are that the 5V voltage regulator is fried.
