Assuming the screen is completely black when this happens, you probably have the very common NVidia chip defect:

Apple will replace your machine if it's still within the 4-year window detailed in the web page above. I'd take it to the nearest Apple store and tell them you suspect the defect, at which point they will connect it to a testing tool and give you the news when they are done. I would print out the web page above, just in case you are unlucky enough to get a "genius" who is unaware of it. Some of the earlier models of relevant machines are starting to fall outoutside of the 4-year window, but a lot are still eligible.

If you feel like doing more testing, you can always connect an external display. If there is no image on an external display, that is further evidence that the chip on the logic board is bad, and that there is nothing wrong with the display hardware.
