help with Dimage E500

everything works except black screen??? pictures are black screen as well, maybe stand by mode? how do i fix this.

 

I saw this happen recently on a camera that had been dropped in the water. It sounds like some of the electronics that capture the image are malfunctioning. It's possible that the screen is dead, but you can rule this out by taking pictures, transferring them to your computer, and seeing if they're still black.
