Dropped phone. Why striped unresponsive screen, yet phone audio and m

I dropped my phone. Now, as I turn on the device, I can hear all the audio activity. But the screen lights up with numerous vertical lines. Some thin, some wide, and some others even wider. Within a few minutes, the screen fades to black. No apps showing, nor am I able to use any of the four icon buttons at the bottom the phone. I can still use the volume, and can hear chimes of when incoming message actvity or other notifications takes place. In fact while its on it even prompts my wake alarm as I had t set before the drop. Can't silence the alarm unless I take the battery off, as there is nothing on screen for me to select. Is there any hope on repairs for this device.
