OK, this comes from my many decades in the electronics industry.
1. PULL the battery. Do not put it back in in few hours.
2. Where did the water come from? Was it really water or? You need to know this. It's real important because mostlikly the PCB is contaminated. Anything that got inside has most likely contaminated the board and will cause shorts, intermitent contacts and the like. Even rain or spring water, it's the minerals...
What you have to do most likely is disassemble the unit. Get a gallon of DISTILLED (not Spring) water. Distilled, also know as deionized is free of all minerals. You are going to have to carefully submerge the board without the LCD in the water and gently rub it with a very soft tooth brush while underwater. Next take it out and put in another bath of distilled water. Agitate it gently. This proces should remove any contamination as long as the offending liquid is not sticky or heavily acidic or base. In the case of the later 2, you are most likely screwed.
Ok, so now you have a wet board. Genly shake the excess water off of it. Turn your oven onto WARM. Nothing above 150 F. Let it warm up and then shut the oven off. Put the PCB in the middle of the oven directly on the rack, close the door and come back 8 to 10 hours later. If the board isn't dry, repeat the steps again.
If you are luck and didn't fry it from trying to power it up, it may work again.
I have saved lots of radio equipment from rain & saltwater submergence this way.
Feel free to PM me if you need to. Good Luck.
