Well, I am pleased to report that I received my replacement shutter release asssembly today and it being a rainy cold day I was glad to have an indoor activity. Refer to Angeloweb's post for order instructions. My repair was successful. As Angeloweb reported, this is a tedious job. If your eyes are over the age of 12 years I would recommend having magifying glasses like jewelers and dentists use. And a flashlight. I used an exacto knife to gently pry loose the old assembly. This was the right tool -- if I had it to do over I would use the same. I did not re-glue the new part. It is not going anywhere, and this will facilitate doing it all again if needed.I recommend using your other camera to record what things look like before removing each part. Also, make notes about where each screw goes. The most tricky part is inserting the new part into the main connector. It's a matter of gently wiggling and pushing, but you are pushing a flexible thing, like the proverbial wet noodle being pushed up hill. If you take a photo of the old assembly before unplugging it you will have a bit more confidence knowing when you have gotten the new one in far enough. I would not grip the circuit with anything metal -- this is a very delicate part. I was very gentle removing the old one, but some conductors got cut anyway. Take your time, don't force anything, make good notes and you will get there. Examining the old part I can't see the defect. There is a slight indentation where the plunger pushes on the white membrane, but I don't think that is culprit. Pressing the membrane there is a dentent -- but the old one does not work and the new one does. Maybe it's the solder joint(s), but I can't see them well enough to tell. Why did the Deoxit work for a while? A mystery. So at least a couple of us have fixed the S100 with the factory replacement part. Good luck to those who go for it in the future.
