I have a Fujifilm F40fd, which I bought around two years ago. Recently, the LCD's back-light stopped working, so I can't really use the viewfinder. How should I get this fixed? When I say back-light, I mean if the sun is directly on the screen, you can see the 'Fujifilm' logo when you first turn it on, so the screen technically works, but whatever is lighting it from inside is broken.
