  12. Canon PowerShot S100 Lens Assembly Replacement, Label Screws on Camera Back: step 12, image 1 of 1
    • On back of camera are seven screws around opening through which you can see back of CCD & lens assembly. I recommend numbering them with a marker & putting corresponding numbers on your project mat to keep the screws organized as your remove them.

    • Label screw on far left #1 and procede clockwise.

    • Remove screws 1 & 2 from camera back.

    • Remove flash unit from camera. Handle flash unit carefully, as it contains a capacitor which can shock you (but no need to be super worried - I've done this lots of times and have never been shocked).

    • Turn camera over and remove lens assembly. This may take a bit of wiggling. Lift bottom right corner slightly, then pull lens assembly gently right and it will slide out.

    • Follow steps in reverse order to reassemble. See next steps for reassembly tips.

    • If your replacement lens assembly does not include a CCD (sensor), you can swap the CCD from the old lens assembly to the new one.

    • Carefully scrape 5 glue dots from edges of CCD on old lens assembly.

    • Remove 3 screws securing CCD to back of lens assembly and remove CCD, noting any tiny brass washers/spacers that may be present where screws were. Remove CCD, being careful not to touch or get dust on sensor surface.

    • Carefully remove rubber infrared filter gasket and infrared filter (small rectangle of bluish glass) from back of old lens assembly & install on back of new lens assembly.

    • Install CCD on back of new lens assembly (may or may not need to use brass washers to get alignment right for correct focus).

    • Note: S100 & S110 CCDs are not interchangeable - ribbon connector for the S100 lens assembly is larger, & does not fit on the S110 board connector.

  19. Canon PowerShot S100 Lens Assembly Replacement, Reassembly Tips: Lens Unit: step 20, image 1 of 1
    • You may need to remove a sticker on the back of the replacement lens assembly to uncover one of the screw holes (screw #7).

    • Rotating the lens assembly slightly counterclockwise as you get it into position can make it easier to get it fully seated.

    • It may be easier to get the ribbon cables for the new lens assembly plugged in BEFORE replacing the 5 screws that hold the lens assembly to the camera body. Lower/smaller one is especially tricky - I have found that it is easiest to get it fully seated with the lens assembly not quite in place.

    • If, after completing reassembly, lens error persists, double check that lower lens unit ribbon cable is fully plugged in (can be hard to get it all the way in). If it is not fully seated it will cause a lens error.

    • Display slides in from the right, with tabs on left end that hook into metal camera chassis.

    • Lower/right end of lens bracket hooks in first.

    • Upper/left end of lens bracket weaves between projections on metal camera chassis.

    • Rear control panel screws go on the outer edge - easy to accidentally put upper one into hole where display bracket screw goes.

  21. Canon PowerShot S100 Lens Assembly Replacement, Reassembly Tips: Top Case: step 22, image 1 of 1
    • When replacing the top case, remember that the end screw goes on the right end of the camera (the screw hole on the left end is filled by one of the outer case screws). There are two screw holes on the right end - this screw goes in the hole on the left/closer to the rear of the camera (again, the other is for one of the outer case screws).

    • If all goes well, camera should power on and prompt you to set date/time.

    • If the lens extends and the display turns on but is blank, remove the front case and disconnect display ribbon cable, then reconnect it (under rear control cable - see step 8). This can happen even if it seems like it is fully seated, and reconnecting it will usually fix it.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Great guide! This worked perfectly for me getting into and out of my S100. I didn’t have a replacement lens assembly though so I went deeper and pulled the assembly apart to see how it worked. Have you ever done that, and successfully revived a lens assembly that seemed high friction?

Reassembling the lens assembly was like a 3D puzzle. Had never seen anything like the helical guides inside the lens before. I wasn’t able to make the assembly work again but its failure mode is different now haha. Was previously no motion, lens error. Now it edges open over 3 tries then closes itself on the 4th try. Progress, maybe? Thinking of trying a bit of grease. Or a new lens assembly.

Tried finding out problem in Powershot S200 lens assembly (which mechanically similar to S100’s), and disassembled it completely two times without finding anything to fix there. It was just an unexpectedly started lens error (no shock or sand) which kept the lens fully extended. I could not pin-point the problem to any specific functionality (zoom, iris, focus, IS): everything looked like fully functional and clean. Tried also cleaning the photosensors telling the positions of the different mechanisms, but no luck. The only positive thing was that I was able reassemble the 3-D puzzle two times without changing the failure mode.

Opening the barrel anyway resulted in so much dust in there that continuing fixing it was anyway unfeasible. So I ended to buy a repair part from AliExpress, and it fixed the problem straight away. I saved the failed assembly: may be some day I have to replace some subcomponent in the lens (e.g. IS) for which I now have spares (hopefully not - a clean room would be needed for that)…

My replacement lens assembly failed after 3 weeks, with the exactly same symptoms! But this is actually as expected because the root cause is the internal design of the lens assembly used on Powershot S100, S110 and S200, which will cause them to fail pretty much after a given number of power on/off cycles. (The repair part I used was definitely a used one; I do not expect unused lens units being on the market really anymore.)

Technically, it is typically the FPC (flex cable) of the diaphragm assembly that gets a sharp turn which cracks its conductors. So if you carefully open the lens assembly in a clean place, you can just replace the diaphragm unit with its cable and save plenty of money in spare part price. But most important, if you open the lens, you can also add some tape to stiffen the diaphragm cable to avoid sharp folds — it (may) increase the life-span of the cable and therefore opening the lens is worth of it instead of just replacing it.

Interesting! I have never attempted a repair on the lens assembly, although I have thought about it. There are several broken ones in a box on my desk that I could have a go at with nothing to lose. I’ll be interested to hear how yours progresses. It would be nice if there were an easy way to test the lens assembly without having to put the camera all the way back together. In any case, I’m glad you found the basic guide helpful. I wanted to include animated GIFs for a couple of the steps, but apparently the iFixit platform doesn’t allow that.

Note: I’m not having a conversation with myself - this is a different Evan.
