Hi guys, this situation happened. I've been using my Canon 50D for less than a week, I was taking a photo on an almost completely drained battery, and suddenly it turns off and at the same moment there is a very loud crack/click from the shutter side. The sound was very strong that I was scared, then I immediately put the battery on charge and decided to see what happened, I take the lens off and see that the shutter is closed and the mirror is completely uphill as in the photo. After I inserted a fully charged battery into the camera but after that it did not give a single sign of life, absolutely none. I have searched the internet and 100 times tried to remove the cf card and the battery that is responsible for the time for 6 hours, the result is nothing. Please advise something, maybe somehow I can do without service
