it has no video?

Well, initially, I'm thinking that your memory card is just plain full, thus enabling you see what you've taken, but preventing you from taking any more. As the camera has both a memory card slot and a small internal memory, have you tried removing the card and taking a picture to the internal memory? If you don't have a xD card in the memory slot, you've just quickly filled up your internal memory with pictures and video.

I'd transfer all the photos and videos onto a PC, delete them from the card and then see if the problem persists. I'd also try a different xD card to see if you can duplicate the problem.

Try and duplicate the problem using another Battery or connected to your AC adapter.

And double check that your LCD settings are proper.

Those are a few things to try. Short of you dropping the camera and suffering some sort of internal damage, I'm thinking it's a relatively minor issue that can be solved by the steps above.

Good luck.

Additionally, the contacts may be soiled and need cleaning. The card may not be properly "seated" try removing it and then putting it back in.
