Welcome to iMore! Reset your device by holding the power button and home button down simultaneously until you see the Apple boot logo. If it still won't turn on it could be a hardware issue. Contact Apple Support or take your device into an Apple Store, especially if it's still under warranty or you're covered by AppleCare+.
