Logicboard problems after liquid spill.

I have a MacBook Pro 13" model, that I have owned since Dec 24 2012 (it wasn't a Christmas gift).

I managed to spit Mountain Dew on it, not pour but spit, as you guessed it stopped working,but after letting it dry out it worked fine, so I kept using it after cleaning the top of the logicboard.

But, then out of nowhere it stopped working again, so I sent it to a technician and they cleaned it again and got it to turn on, but literally a few hours later, again it stopped working, so I opened it up and cleaned the other side of the logicboard. Again, it continued to work until today, it stopped, so I opened it and cleaned but with no luck, there's no sign of life except, on the MagSafe, which has a very very very faint green light on it.

I've tested some of the components on the logicboard with a multimeter and there showing the correct voltage. But, somehow in all of my stupidity I shorted the DC in board when I was testing its volts. The logicboard SEEMS fine, but there's no sign of life besides the voltage on the logicboard. I need help because I'm stumped and the nearest apple technician is 3 hours from here.
