Contact with water is one of the worst things that can happen to the Nokia 3230. Without quick action, the components on the circuit board will become corroded and the phone will either start to act strange, or will become totally useless. If you remove the battery quickly enough, and get rid of all the moisture, there is no reason why the Nokia 3230 can't survive contact with water. Even if some damage has already appeared on the control board, there is still a chance of repairing the device.
Instructions
1. Turn the 3230 over. Push the battery cover toward the bottom of the device to remove it, then pull out the battery. Do this step as soon as possible, regardless of if you are ready to move on or not. Water generally doesn't damage circuit boards without the presence of electricity.
2. Insert your pry stick underneath the plastic piece on the top of the device. Push up to remove the piece.
3. Remove the four screws, each located at a corner on the back of the Nokia 3230. Place your pry stick between the front and back covers, and lift up to remove the front cover.
4. Pull up to remove the metal cover around the LCD. Use your pry stick to separate the LCD connector, located above the LCD, and pull the LCD away from the board. Pull up to remove the keyboard as well.
5. Unscrew the four T6 screws that secure the chassis, which surrounds the interface board and control board. Pull up on the chassis to remove it once the screws are out.
6. Life the interface board up slightly and use your pry stick to release the connectors located under the interface board near the port at the bottom of the 3230. You can then lift the interface board and the main control board out of the back housing.
7. Inspect every piece of your Nokia 3230 for moisture and blot up water you can find with a paper towel.
8. Place all the electronic pieces into a plastic bag. Place several silica gel packets into the bag as well, and seal it closed. Put the bag aside and wait 48 hours before you continue.
9. Remove the electrical components from the plastic bag and lay them out on a table in front of you.
10. Apply some isopropyl alcohol to a brush and scrub down every piece of electronics. Use enough pressure to clean the board, but not enough to damage any components. Visually inspect each piece when you are done and the alcohol has dried, which takes a few minutes at most, for any signs of corrosion. Corrosion will look like a white or green substance on the components. Scrub away any remaining corrosion that you find.
11. Put the device back together by reversing the disassembly instructions.
