I dropped my camera into the water

So, the other day, i dropped my nikon D90 into the water. I took it home and put in a box full of desicants. This morning, I put the battery in and found out that the LCD works. But my dad told me not to snap a photo because it could still short-circuit the camera even though the LCD works. Is that true!

Send it in right away to Nikon. You can easily damage the camera further.

Call them at 800. NIKON-UX
