Shutter doors out of alignment/won't open

If you mean the lens (the barrel that's supposed to extend from the body), try these procedures.

Try a slim jim first, down the side of the window. Or AAA or locksmith. If no luck, remove the seat first. Find the screws and bolts around the door handle and arm rest. Most Ford's have screws around the outer side of the panel. I don't believe your's does. The panel lifts or pops off. Once the panel is off, you can reach down and open the door. Just a note. I have done some to where the panel came out in pieces.

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, sometimes with lines, especially when taken outdoors (for shutter stuck open). To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.
By the way, my wife happens to own a SD1000. Great little camera, but it's prone to stuck shutter every once and a while. Easily fixed each time though by simply opening the battery door while on, and gently flicking the lens barrel a few times. Again, see the link.

Confirm tht DX shows in LCD. If not then press and hold shift button then press ISO so "DX" appears.Open Camera Back. Insert film cartridge, pull film leader out to right and align with red index mark (inside film chamber on right). Make sure there is no slack in leader.Close camera back until lock release snaps closed. Fully depress shutter until film advances to first frame.
Confirm " 1" and film transport show in LCD. If Film is not loaded correctly, "ERR" show on LCD. Open cack and reload film.

A stuck lens cover is a fairly common problem, but it is normally easy to fix. A single grain of sand jamming the cover mechanism is normally the culprit, and you want to try to dislodge it. There are many non-invasive techniques that people have come up with to accomplish this. Some may be seen on this blog article. You can also open the lens barrel up to fix the covers, but only as a very last resort. The article also gives examples for this type of procedure.

I was THRILLED to find this fix for my camera when the shutter wouldn't open. The 590 is a little different than the 540 in these pics, but the solution still worked. I didn't even have to do as much disassembly as he did--just had to take the little circular thing off the top of the lens, and clean the little flap things inside.

Open the film door and see if the shutter cutains are aligned straight. If not the curtains are at fault. If not the gearing is bad inside your camera

I had this problem, and I fixed it by flipping the battery around. It looks like it's supposed to go one way, but it's supposed to be the other.

Try checking this... on the battery door (the outside door) along the top edge (over the CF card pointer embossed in the back of the door) you should see a little plastic piece that pokes out... tis is supposed to push a small switch located in a slot over the battery compartment. It's the sensor that tells if the battery door is open or closed.. if the plastic part breaks off or gets chipped it wont push the button and the camera will not turn on when the shutter door is opened.

It is impossible for the Shutter to be stuck, as the A40 does not have a Shutter. Sounds like you have a bad image sensor. I would contact Canon about this as they acknowledge a defective sensor in some of their models. However, depending on how old the camera is and depending on if it is one of their recognized defects, you may have to purchase a new one. Wait, what do you mean by shutter? do you mean the little covers on the front that open to exspose the lens? the little curtin like things? Tap on the front this can sometimes snap them open. If you can see the glass in the front and its still black, make sure your "display" button is not set to the off mode. Sometimes it can power on and the display will be off because it was turned off before the last time you used it. If its still black it could be a bad connection inside, wich controls the camera section inside the unit. If you bang or bump the camera ont he side will the screen flicker or show purple lines? sometimes show an image?
