If the screen powers up briefly, it could be the display inverter, which is a module that supplies power to the back light. Typically with a faulty back light, you can still see an image on the screen if you squint and have it in the right light.

Regardless, if you dropped it off at a shop, it should be very easy for them to diagnose a screen problem. All they'll need to do is hook it up to an external display. If they get video on the external display, then it's isolated to the screen. It's rare for an LCD panel to fail outright, so it might just be the inverter, which is a roughly $70 part. I would personally charge about $100 in labor, which is assuming about 2 hours worth of work.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!
