Screen, apple logo, caps key and chime not working!

So I just got my brand new MacBook Pro (15' w/ retina display) and I was using it normally.

I had to install a CAD software that only runs on windows so I used BootCamp to do it. As I was finishing to set Windows 8 the screen went completely black. I forced the computer off and tryied turning it back on without success.

Now it turns on but I only know it does because USB powered stuff turn on as well. The screen is completely innactive, caps lock key does not light up, no noises are made (SSD hard drive), the chime doesn't play and the apple logo on the back does not light up... And it's Sunday so no tech support.

Any help?
