It could take a week to completely dry out the camera.
Open the battery compartment and remove the batteries.
Remove the memory Card.
Open every door on the camera that you can find.
Sit the camera on a sunny window sill (lens facing away from the sun).
Let it set there for a week before even trying to use it.
One week later.
Clean the battery contacts on the battery and the battery contacts in the camera.
Clean the contacts on the memory card.
Install battery and memory card.
Cross your fingers.
Turn the camera on.
I have a Panasonic FZ20 digital camera. I forgot it outside and it rained on it. We got 4 tenths of an inch of rain that night. The display window fogged up. I took the screws in the body of the camera out and opened the camera up a bit to try to get rid of the condensation. The display window is now clear but when I try to operate the camera I have to slide the switch on "Off" for the camera to turn on. I can not use any of the controls except for displaying the pictures and then it will only display the last picture that was taken. Should I give the camera more time to dry out or did this rain ruin the camera?
