mac air screen not displaying correctly

I have a Mac Air 13' screen. Recently I was using it and someone put a lemon head on the keyboard and slammed the screen down on it for no reason.

The screen is now displaying a grey screen with a white vertical line down the middle. When I turn the computer off and then back on the screen is

exactly the same. When I type I cannot see anything that I type. I have a two year warranty on my computer. I am just wanting to know if there is anytthing

that I can do without sending it in. If there is not, who or what am I supposed to call to send in the computer to fix it. Also would Ribbit computers or another computer repair store, would they be able to fix my screen without me sending it in to Apple. Any information would be appreciative and very helpful! Thanks for reading!
