I am suddenly having problems with my S100. It will not take the picture when I press the shutter release. In case I had accidentally changed something, I did a Reset to Defaults. Then it worked, briefly, before returning to not working. It also would not let me change My Colors. Everything else seems to be working fine. Any ideas?
I agree that just re-soldering will probably last a very long time. After all, most of the s100's out there never fail in this way. Too many do -- especially when one of them is mine. I think that on those that failed the original soldering was not quite hot enough,or the mating surfaces were not close enough or not enough flux flowed. I would be tempted when reheating to add a tiny tiny bit of additional solder -- if it looked like the original was skimpy. Also, now that we know the weak link we will take care not to press the shutter too hard.
Every OEM has their dirty little secrets, I bet even Nikon. As far as the S100, I bought a used, working one because of this very, very long but informative thread, I bought it because I was confident if the shutter did fail I could fix it ( because of the great information here) and also because it has an optional waterproof case made by Canon. I wanted a protected camera, protected against the water, sand, etc. and I bring mine to the beach and the lake all the time. It takes good quality pictures in wet environments, with the case of course, and is very compact. I do agree that Canon should have manned up to this shutter problem a long time ago. I think this is the longest thread on this forum or maybe the second longest and it is proof some S100's had this defect.
