I found out that this issue was actually due to the power button getting stuck somehow. In my case, it was due to its being left in a backpack during a volleyball game and stepped on.
To fix it, you need to remove the back plate, soak it in alcohol and contact cleaner, then blow on it with high pressure air. It took awhile, but eventually it came back to life.
