I feel sure this is a matter of adjustment, not replacement parts. I'm sure a camera guru somewhere could sort it!

AFAIK, auto focus on these cameras is closed loop using contrast detection, so it's not clear to me what kind of simple adjustment would make the difference between working and not. There is software calibration related to some electromechanical elements, but the software and the details of exactly what it does are normally only available to Canon service.

There have been a few instances of cameras misbehaving due to corrupted firmware (see this thread https://www.dpreview.com/forums/post/63994949 and technical details on the CHDK forum https://chdk.setepontos.com/index.php?topic=14052.0) but in general that is more more likely to cause crashes. While I think this isn't likely to be the cause, I can check if you make a firmware dump.
