Canon A620 The power on/off button is stuck in the on position and will not turn off. Any ideas??? Thanks in advance.

Press the DICP button 2 - 3 time and see the LCD turning on or not. Let me know.

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.

First try pressing the DISP or DISPLAY button on the back of your camera. If that didn't fix it... A stuck shutter is another common failure mode for digital cameras.

My A620 JUST started doing the same exact thing last night. LCD works, lens works... but something possibly wrong w/the shutter so it won't open.. everything black.

Sounds like you might have accidentally pressed the DISPLAY button on the back of your camera. It turns the screen on and off to save batteries. Turn on your camera, and press this button once again to turn the screen back on.

But if your camera is also taking black pictures,

If the camera shows the menu, it can be two faults - dead CCD or stuck shutter. You should contact local Canon service center.

This blog post outlines repair procedures for stuck lens covers. An A400 is used as an example. The A620 is more complex, but still similar enough. As recommended in the post, try the simpler fixes first before attempting:

this may work for you
1. Turn off printer
2. Hold down Resume button and press Power button.
3. Keep holding down Power button and let Resume button go.
4. Press Resume button 2 times then let BOTH buttons go.
5. Green lights will flash and then stop blinking.
6. When green lights are solid, press the Resume button 4 times.
7. Press the Power button and the printer should turn off, if not,
press the Power button once more.
8. Your printer should respond as normal..

Again the same old compact camera zoom lens problems - sand in lens, stuck AF motor, chewed up plastic gears...you only have to look at them wrong and they will die... (A very cynical camera repairer that has tried to repair these damn things soo often!!) Even cameras with internal lenses like the old Nikon 950/990/4500 still have troubles with stuck motors and broken lens parts. I despair - these things are just made to last the guarantee out (if that long) and die horribly afterwards!!
