My Toshiba laptop starts up but screens black

Hello,
My toshiba laptop needs major help, and I dont know what to do. Here's that happened... I was sitting on the floor with my laptop, and my son ran by and stepped on the keyboard, the screen froze, so I just turned it off. When I turned it back on, it would run for 5 sec (the fan, lights, etc.) and turn back off. Now, it will stay on, but the screen is black. Is something like this fixable??
