Hi,
after fall my camera stoped working. The camera fall only from 40cm down to branches of tree. The camera was totaly out of energy. The viewfinder was totaly black, no LCD and no control LED was flashing.
So, I very carefully disassembly the back part of camera (with LCD screen) and look inside (one screw was invisible under rubber at the corner). No connector was fallen, bud when i push down to power board (is situated under little LCD screen with metal boxes), the board clicked back in original position. When I try to put the battery back, the camera was working.
I hope, it can help you.
With regards,
Martin
