Where do I find the instructions to open up the front and back casing. I suspect a corroded micro switch and would like to test them individually. All the readily accessible screws are off, back panel cam/review switch in cam mode but the front and back casing are 'stuck' on their top portions; how to take off the top rotary mode selector?
The camera mode opens the lens, one extended, power shuts down. Review mode is fine.

Things to check first are battery contact points, and micro switches that are located on the battery and memory card doors. Details on what needs to be checked may be seen here. It won't work for every case, but it's worth a try.
This is an old A70, but the way it's done is very similar as I don't think this has changed much over the years. It's a pin design that you have to push out with a stiff unbent paperclip. You push in on the side with the smaller hole. To access the pin you'll need to remove the front and back case covers. See the following:
When I got my A70 I got a CD with the software. If I connect the camera with USB cable to the computer, set the little lever on the back for the camera to display whatever pictures are in it, and turn the camera on, the computer recognizes the camera, opens the software and leads me through the process. If you have some other photo software than the Canon software, it should still work.
if you can disassembly the camera and put it back again why not...but the problem is the ccd image sensor if you can buy it in the canon service center...that sensor is located at the center of the lens with a glass,square shape and have many pins..
The top is held in by two plastic snaps, one by the on/off button and the other beside the Canon lettering. The trick is to press down on the front half of the casing with your left thumb (on Canon logo) and use your right hand to gently twist the back half back and forth while pushing out the bottom until the snaps release. Be patient and it will eventually come apart.
The mode switch is a very common problem that causes the camera to remain in either play or camera mode. The stem breaks off the top of the switch and no longer functions. If this is not the case, the flex harness (operations unit) can get torn on top if the camera has been dropped. If the switch appears to be good, check for ground switching between the two outer legs of the switch, the micro gets a low signal from the mode switch to determine what state the cameras in.
Good luck, this is a nice camera!
I dont know about formmating CF sandisk card with canon A70, however, i can recommend another method: hook it up to your desktop and format it through a CF adaptor. It may take a couple of attempts. it didnt do any damage, at least not one that im aware of. Im not 100% sure though, so don't get me responsible in case it will damage yours. anyways, if you do it, you can try the process described above.
