Re: shutter release not working S100

Just an update on the DeoxIT fix (Post #186).  The camera has been working fine since I used the DeoxIT on the shutter switch.  Have taken around 200 photos since the fix without a single glitch. 

 

It’s possible that you might be able to use the Deoxit directly on the shutter button itself instead of disassembling the camera (as John had suggested in an earlier post).  I didn’t look at the penetration that the shutter button makes through the case top to see if it has any kind of seal, so I can’t say for sure if that would work or not, but if you have nothing else to lose, and don’t want to disassemble the camera, it’s worth a try.  I’d get the Deoxit in the bottle with the needle applicator (you can find it on Amazon or any number of places).  Take the battery out of the camera (always a good precaution when working on anything), push the shutter button down fully and put a few drops in the crack between the silver shutter button and the black ring that surrounds it.  Hold the button down for several seconds, then operate the button a bunch of times to distribute the DeoxIT.  Put the battery back in and test.

 

A few warnings:

  • I take no responsibility for this fix – if you break it, don’t blame me.
  • If if at some point Canon decides to do the right thing and repair these cameras under warranty, you might be out of luck if you’ve tried to fix it yourself.
  • Make sure you use DeoxIT, and not some generic “contact cleaner” or “tuner lubricant”. Some other brands can damage or soften some plastics. DeoxIT is expensive – around $25 for a bottle.
  • If you do disassemble the camera, be extremely careful around the high voltage flash components on the left side of the case – even with the battery removed, it’s possible to have hundreds of volts on the flash capacitor, and thousands available on the secondary coil. Not sure if the capacitor voltage is bled off when this camera is turned off or not (my Sunpak 622 holds a charge for days), so just be careful. This warning goes for anything that uses a gas discharge tube type flash.

Re: shutter release not working S100

Thanks for the update !

I doubt Canon is going to act on this at this point they are all hiding...it's a shame.

I would definitely try using the DeOxit without taking the camera apart first and yes DONT USE THE CHEAP STUFF !

DeOxit is the only product I am confident with, like you, for an application into a camera.

I'm happy to hear your camera is still working for you !

I would be willing to look at a few of these cameras for free just to satisfy or at least try to satisfy my own curiosity as to whether there is more than one chronic fault in these.

Seems I and you are more curious than Canon as far as getting to the bottom of this situation

Re: shutter release not working S100

It's definitely a shutter button issue.  When the problem exists on my camera, I am able to get the shutter to trigger immediately by putting the entire surface of my finger over the shutter button and the zoom ring and then rocking the whole shutter/zoom assembly while pushing down to take a photo.  Every time.  That said, it isn't consistent on which way I have to rock the assembly.  Sometimes it is forward, sometimes side-to-side, etc...  

 

I like the Deoxit solution if it works, but I am not entirely sure the liquid can get anywhere of value from the outside (unsure if the button is sealed from the outside world).  Looks like a dissassembly may be in my future.

Re: shutter release not working S100

well the good thing with the DeOxit is it wont harm anything and may help without taking the camera apart.

You've narrowed it down to the switch or the internal mounting of the switch.

Have you tried the other solution yet...blowing air into the ports on the same side as the shutter switch ?

No, and am not planning on it.  At least, not with my mouth.  Perhaps with compressed air at some point, but I'd rather get at the switch internally before I go down a route that, although seemingly successful in many cases, seems a bit coincidental as to fixing the issue.

Re: shutter release not working S100

yes it could be coincidental indeed. An air compressor set real low will also introduce less if any moisture.

There is only one way to get to the bottom of a solution and that is repeatability or measruement of continuity through that switch.

Re: shutter release not working S100

Just an update.

 

I did take my camera apart and it was inspected by a friend who is familiar with electronics (he has made circuit boards for several devices).  His comment was the solder around the shutter button looks fine.  I did squirt it with DeoxIT and we put it back together.  No problem ever since but we have only taken about 100 photos.  I will update after our trip at Christmas as we will be taking a lot of photos with it... fingers crossed.

 

A piece of advice while taking it apart film yourself as you do it in case you have any questions on which screw goes where.

The black S110's are $179 at various retailers too.

Re: shutter release not working S100

I agree, some of the screws in those cameras are only 0.5 mm different in length or 0.25 mm different in width or thread size...way to easy to get them mixed up.

I looked around the auction site and Canon actually has a better price at $109.99 than what I saw there for a used, non OEM refurbished camera from some person who said its tested and works.

I was looking for one that specifically stated it has a shutter button problem.

 

msostrowski...when you took it apart did you notice how the circuit board that holds the switch is mounted in there?
