Welcome to Android Central! If the screen is completely dark but it's still ringing, I'd suspect a faulty screen. If you hold the power button for 20-30 seconds, then wait a few seconds, and then power up again, does it vibrate as if it's booting up? If the screen remains dark, then you'd have to consider getting the screen replaced.
