Help with a camera problem

[jesta]

Hey guys,
I lent my sister my compact digital camera to use for one of her uni parties and she told me she accident dropped my camera when she was uploading her photos.

Problem with the camera is that it can't take any photos.I believe its the lense that is the problem because the LCD works fine and so does everything else. Is there any proper way of diagnosing if its actually the lense and what is broken?
I assume its probably not worth repairing the lense if its the problem as I can get another digicam?

Thanks

It auto focuses fine,the zooming seems to work(you can feel the zoom moving inside of the camera.Basically when you take a photo it produces a black image oh and as the LCD is the viewfinder the view is also black. The photos I took to see if it works are also black.Which I believe is cos the lens is somehow broken.
Oh and no error messages come up.

Thanks
