My laptop screen (LCD) stopped working after the Left Hinge broke last night.

Last night, I was about to shut down my laptop. When the screen says "Shutting Down", I tried to close the lid and I heard a crack sound. I ignored it and closed the lid and suddenly the HINGE broke! I don't know what happened.
Can someone tell me what happened? I searched last night that this is a common problem. Please anyone tell me why did my screen stopped working? I tried to open my laptop and.. well, it turns on I hear the Windows Startup Sound but my screen is like not working.. It's black. No cursor or anything.

Please someone explain this. Is the hinge connected to the LCD Screen?
Before I go to the Acer Service Center tommorow. Thank you.
Help would be appreciated.
