You may have a problem with a stuck shutter lens. Try putting the shutter on auto shutter. Also try tapping around the lens with a solid object to loosen the shutter to make it operate again. Try shooting bright objects and see if will respond again. Try shaking the camera by the lens carefully. Make sure you do not damage your camera with any of these fixes. If this does not work you may have to have a service center look at the shutter mechanism to free it. It may also be another problem with the camera. The pick-up circuits may have lost power and are not working correctly. This type of problem will require service from a service center. I hope this information helps you with your problem.
