Question about Canon PowerShot A720 IS Digital Camera

1 Answer

Cannon Powershot A720 IS, wont turn on.

I purchased a Cannon Powershot A720 IS 12/07,it wont turn on it is frozen with zoom lens out,I replaced all the batteries. I had dropped it before but it still worked untill recently. Where can I send it to to be checked or what else can we try. Circuit City is sending me a copy of the receipt. My daughter seems to have misplaced the manual so I don't have a phone number or address to get ahold of someone since Circuit City said I needed to send it to the manufacturer.

    Our Powershot A720 was purchased in October, 2007. We have the same problem. It won't turn on, has new batteries and the lens is in off mode.

Log onto and in the canon consumer search bar at top type in a720. On recommended links, click the first one which will be the a720 homepage. Once you see the image of the camera and 7 tabs below, click on drivers and downloads.

Look under Guides and Manuals and you will find what you are looking for.

Hope this helps!

SOURCE: the focus on my cannon powershot A540

Do you focus and then push the shutter button half way down to lock in that focus? Then all the way to take the picture?

Do you support the camera on a tripod or kneel down and support your arms on one knee or lean against some object to keep the camera steady> You can even press your arms tightly against your body before you focus and shoot. And be sure to press the shutter button very gently when you shoot so the camera will not shake or move.

Do you have the camera on the right mode for the photo you are attempting to take? Such as night/macro/action/ etc. Try taking photos on just the automatic mode to see if you can get focused shots. Make absolutely sure your camera is not in Macro mode ( a picture of a little flower on the screen) unless you are doing extreme closeup shooting.

Go to your menu>then setting> then set your camera back to default settings if you can. Or if you are unsure how the camera is set. If you do not have your manual you can go to the Canon website at and click on support or downloads and find the manual for your camera and download it. That may give you the answer you need as well.

Please get back to me if you do not have any luck and send along more info such as camera age.

SOURCE: Black Screen; Change Battery Message

My proposed solution is valid for a Canon PowerShot A300 (digital)

Hi there! I had the same problem with my camera and called Canon as well. They gave me the option to have the unit diagnosed (free) and serviced (base fee $80) or the option to trade it in on a newer model (my unit + up to $110 for refurbished unit).

After talking with the representative for about 15 minutes I advised him that I was going to look at the pros and cons of the units available and call them back after I had made my decision. However, right before I hung up the phone he advised me that sometimes this trick works:

Take a pencil eraser and clean the battery connections well on the outside (the little black flip up piece) and down inside. Just make sure that you clean it out well and don't leave any foreign objects in there (i.e. eraser flakes). I learned in cleaning mine that it's best to do it in a well lit area and the battery connections inside the camera push down a bit so make sure that you're gentle but you should clean the entire area in there.

As soon as I finished cleaning the connections and put my rechargeable batteries (which have been lying around for a few days without being recharged) back in the camera powered on and I have taken about 40 pictures since.

I hope this works for you as well.

I have the exact same problem, took it completely apart removed the zoom motor, physically turned the zoom gear and retracted the lens, reinstalled the motor, put it all back together, and found that I had the same problem and the lens wouldn't move out, so im pretty certain that the motor is bad, as the lens moves smoothly once the motor is not attached to it... looking for a replacement motor as i type...

Can't take pictures

If the lens is buzzing and followed by an "E18" or "lens error" message then the lens will need to be replaced. If no message appears you may just have flat batteries or even a single bad battery can cause this. Try getting some good quality disposable batteries specifically for digital cameras. If all is well with the new ones, invest in a new set of rechargeables.
