This could be a backlight issue, an inverter issue or a logic board issue. Given that you dropped it, the backlight issue is the most likely because the ccfl bulbs inside the screen are breakable. Backlight repairs are somewhat difficult. As much as I would like to be able to tell you a quickfix that will solve backlight the problem, it's a pretty arduous repair that requires 1-2 hours for a trained person. It's feasible to do it yourself if you're tech savy, but you'll most likely have to google for guides that show you exactly how to replace the backlight step by step. Check on ifixit on how to take the screen apart and make sure inverter is still connected properly. If so, you have a backlight issue. I work for Mac Repair NYC and i have to fix this problem a lot, it's so easy to break the lightbulb in the process.

You've either broken the Cold cathode (a strip light that runs along the bottom of the LCD to provide a backlight)or damaged the inverter board (a chip that boosts the 24.5V of the laptop's battery to the 400V that the light needs to work) unless you fancy ruining your warranty and getting your hands dirty with replacing the board ($40-$90) or the LCD ($400-$600) i'd do as the guy says and have a certified tech have a look at it. of course, there's no fun in that, but you're more likely to get a working machine at the end of the day...

I'd highly recommend taking into the Apple Genius bar. You've definitely damaged something. You might be lucky and one of the connectors came loose, but most likely you damaged the LCD which will need to be replaced.
