How to fix/reset my Emprex DSC7200Z?

After someone sat on my Emprex DSC7200Z, the outer lense half has retracted. Now when I try and start the camera, it beeps 3 times, the LCD flashes a black screen for a second and the LED goes on for about a minute, then continues to flash forever. Does anyone even know what has happened to the camera or how to fix it? maybe it just needs some sort of reset, but i havent found a button that will do so. Any ideas? thanks
