I DID IT!!!! I made the camera usable again. Obviously SSS is not working, but I managed to center the sensor and prevent it from moving up by physically adding some double sided padded tape - basically setting the sensor into a fixed position. Took me 2 hours. Hardest part was figuring out how to disconnect the various flat wires.

No idea if this will burn out some motor down the line but it does not matter in my case. I'll take a guess that it will also affect the self cleaning feature but other than that, I went from a useless camera to a DIY fixed camera that can again be of use minus a feature that one can live without all for the cost of some tape.

Next up, do the same fix on my A100. :)

If you still got those A series cameras with a shifted sensor in some junk drawer, they can probably be resurrected into use again!

Sounds like you disabled the piezo actuators (not really motors) that do the shifting. What kind of disassembly was required to reach them?

No - I did't disable the motors/actuators. I meant disconnecting and then reconnecting the wires on the back circuit board (that sits under the back cover) so that I could get to the sensor underneath it. All the gold looking wires in the first pic.

Process was not bad, take off back cover, disconnect the wires on the circuit board and lift it off, remove the sensor protection plate and that was it. I took some pics... if I have time I'll write up a DYI for it. Would they post on this site if I did that?

Post all you want, we're curious about this endeavor. It'd be nice if you could overlay some arrows or letters in the images for a better description for others who might want to try.

Congrats on the fix, I'll edit the threads title to reflect that.

With compliments
It's a pity that last week I sold my a100 with the same problem for just 40euros...

You can also do it the more crude way. When the stabilization of my A100 gave up after a fall I just took a small screwdriver and positioned the sensor from the front using sensor clean mode. You can stick the screwdriver on the side of the sensor and just move it.

If you read my earlier posts, I have tried that. But the camera reset to be offset after turning it on and off. That is why I had to take this more involved approach.

Thank you!!! Good diy solution. But, let me recommend an easier one. Just disconnect the SSS unit from the mainboard: in step 6, the wires on the bottom of the picture, the third by the left. Bye bye Mr. SSS!!!!

Thank you as well. I was able to fix my A350 with your describption. Unfortunately the link is dead so I had to use a different source to find out how to open up the camera: LINK.

Perhaps I don't have any stabilization anymore, but the picture and composing with liveview and the viewfinder are matching better.
