This is definitely not the normal behavior, so there's likely some electrical problem, which can be anything from wiring to damage on the board. Some things you may want to try for debugging:
1. Make sure with a voltmeter you're getting 5V on the Vin rail (with the correct polarity). 2. If so, check the 5V rail. 3. If you're getting 5V on Vin but not on the 5V rail, try bypassing the on-board 5V regulator by applying the power supply voltage directly to the 5V rail.
