История для "How to find broken part?"

I dropped my camera incidentally. Side part from back case was broken. Now when I turned on, I can't recieve preview picture from lens on LCD display only green or red noise, but still can view icons, pictures in memory, menu. Camera can't turn off from button. So where is the problem - Lens, Main Board or something else? Please help :)
