I recently made a stupid mistake of putting a broken CF card back into my Canon 350D. The result of this was that now the camera only shows "no CF" on the LCD, but refuses to do anything else. No reaction to any buttons, no CF-reader LED flashing.
About the broken CF card: this one must have been short-circuited when plugging it into my card reader while still humid. The reader instantly turned hot.
I've of course tried to remove all batteries, the lens, the CF card (put in another).
Does anyone have any advice?
