I would like to hear from Jakub, but be cautious! You would need your iron to be hot enough to melt solder -- but it would be easy to cause collateral damage. Ideally you would have a temperature-controlled soldering iron with a very fine, clean tip. And you would apply heat very very briefly.

Great post-Jakub this is exactly why I bought a used, working S100 with a waterproof housing for $99 to use at the beach, in pools etc. I was confident, because of all the information found in this very long thread, more like tugboat rope now, that if anything happened I could fix it myself. Switches like this need a stable mount and a flex PCB is not a good idea. You nailed it, great job!

Someone who repairs cell phones might have the right iron for the job. The flex strip is part of the shutter release assembly. Replacing it does not require soldering, but does involve a lot of disassembly/reassembly. See earlier posts on this, and find Youtube videos to see how. I successfully replaced on mine with a new part. Disassemble your parts camera first, to see how it comes apart. Trickiest part is reinserting the main connector with just the right amount of force. Also, there are a lot of screws. You will need a system to keep track of which screw goes where -- they are not all the same.

Thanks for the advice, Dan! Will try to proceed with extra care but I need enought "bile juice" so to speak in Chinese before I do the transplant! Will post after I do it!

Thank you, Jakub! That is good tips! I shall try reheating it first and if it does not work I shall do the transplant. I usually blow air into the soldering to cool it faster! Thanks again!
