MBP Dead after a tiny drop of water

I spilled some water on my table and didn't realize some went under the MBP. It kept on working for the whole day until I picked it up to leave. Then I saw the water when I turned it over. It was just a few drops, but I guess one slid in, because now it's dead.

No noise, lights, fan anything when I press power. With/without battery (fully charged). I tried swapping around all the RAM chips in case one got wet; no luck. Opened it up all the way and nothing obviously wrong. Left next to a heater to dry for 2 days and nothing.

It's out of warranty; any ideas for something I could try? Or if this could be anything cheaper than a logic board replacement (so expensive I might as well just buy a new one)?

Thanks!

PS: Model A1226
