More on possible stuck blade as a cause of overexposure: I did a quick search on issue. According to an article on dpreview, you can use the depth-of-field button on the camera to help determine if the blades are sticking. If you press the button and the viewfinder becomes instantly darker, the blades are functioning properly. If the viewfinder slowly gets darker, the blades are sticking.
When I press the button, the viewfinder grows immediately darker.
Since you are unable to attach a photo, there is really no point in continuing this discussion.
