Hi. My 5Dii's back light won't turn off. I've tried new CF cards, new batteris, nothing works except pulling the battery. I must pull the battery between uses or the light ends up draining the battery. Is this fixable or do I need to send it in?
As a last resort before sending it in to Canon for repairs, check the LCD illumination button, ....
... and the associated illumination brightness setting in the camera's menus.
