How do I fix my Vizio d32h-g9 screen please help?

I have a Vizio d32h-g9 and my son knocked it over. When I finally seen it I turned it on and noticed that the screen has white vertical lines and color horizontal lines .It also looks like it's cracked behind the screen. I can't still hear the sound just the screen is all messed up. Please let me know if it's a inexpensive fix or should I just but a new one thanks guys.
