Camera affected by water now no switch on

Did you dry the camera completely? If not here is the procedure to take out all moisture trapped in the camera: Dry the camera, battery, any accessory, etc. with cloth and wrap each piece, camera and accessories, in newspaper. Place a few handfuls of rice into a plastic bag and then place the wrapped camera in the bag with rice. The newspaper wrapping avoids direct contact of rice with your camera because the dust from the rice can get into the small areas of the camera. The newspaper and rice will absorb moisture. Leave it there (with the bag open) at least 24 hrs.

Water is bad for cameras you can get a new camera just like the one you have now for under $15 on ebay!! :)
