Thank you very much for these instructions - they enabled me to fix the camera after four repair places refused to.
(the two screws holding the shutter button in place had come loose - the button had fallen off and the loose screws inside were interfering with the zoom switch, sending the camera always to safe mode)
A couple of things: It is not necessary to remove the black screws at step 8. They hold something in place in the lens assembly, but don't prevent you from moving to step 10. Also, it is not necessary to remove the screws at step 11 - only the leftmost one in the image. If you are careful of the wires, the battery case can be folded back giving adequate access to the shutter assembly.
Also - when reassembling, be careful at step 17 that the zoom lever is positioned to be engaged with (hooked over) the lever on the brown circuit board.
