Canon A720is turns on, but lens will not extend

My Canon Powershot A720is powers on but will not extend lens to take pictures. It automatically goes to picture review mode. No error messages come up. The report from my significant other is that there may be some sand in the lens mechanism.

Seems as though there would be some sort of error code or noise to indicate the camera was trying to open the lens.

Any suggestions?

    I called the Canon tech desk and they suggested I send it in because it is still under warranty (two more weeks). I sent it in on Monday and had it back on Friday. They said it was an bad electronic board. Have to say I'm impressed with the service. The only cost for me was the $10 to ship it.

    I have exactly the same problem. Unfortunately, mine is no longer covered under warranty. This seems to be a common problem with these. Perhaps there's a defective board.

I had the exact same problem. Since my camera is out of warranty, I decided to try to fix it myself; figuring the cost of repairing it would be close to the cost of a new, better camera. If yours is still under warranty, let Canon fix it for the cost of shipping.

I unscrewed all of the screws and carefully pried open the back of the camera. Part of it will come apart easily, but for the part that wouldn't, I slid a razorblade into the crack between the pieces and used it to separate the pieces.

I was shocked by what I found. The "mechanism" for switching between picture and review mode, appears to consist of a tiny black piece of something (doesn't look like metal, but I assume it's conductive). The physical switch that you operate on the back of the camera, appears to push this away from the circuit board. When that happens, the camera goes into review mode.

I assume that over time, this flimsy piece of whatever begins to wear out and eventually won't return to the circuit board. I slipped a small screwdriver under this piece and bent it back towards the circuit board.

That did the trick, The camera now functions as it's supposed to with one exception. Now, when I go into review mode, the lens won't retract (although it will when I power the camera down). Personally, I'm fine with that, because the lens going in and out is a huge waste of battery.

One thing I learned from this is that when you leave your camera inactive for long periods of time, make sure it's in picture mode, as this should reduce the strain on the flexible "switch".

I had the same issue. Changed the batteries and it worked fine. My diagnosis was low battery power, sufficient to power the electronics but insufficient to power the mechanical lens.

I have a Canon A720is (about 5 years old) that recently has started to show problems.


I think you immersed camera in water. This might have damaged corroded contact of LCD supply line and PCB.

Tip

Working with E18 and cannon cameras




he E18 seems to be a significant flaw in an otherwise great camera.

It is a flaw well know by users of Canon Powershot and Ixus cameras and is currently not acknowledged by Canon as a flaw in camera design.


HOW IT ALL WORKS:

Canon E18 error happens when the lens gets stuck while trying to extend. The camera will beep a few times and the LCD will display a little E18 in the lower-left corner. The lens gets stuck in the extended position, and refuses to move either to focus the lens or to retract when powered off.

Apparently, people who posted about this incident on forums say they had to send the camera for repair and that Canon has horrible customer support and response time.

The problem usually happens because dirt or sand get into the lens mechanism. But it seems that more and more people are showing, who took great care of their camera, and still started receiving E18 errors.

It seems that the problems have been happening with the following types of Canon cameras:

- Powershot A40
- Powershot A60
- Powershot A70
- Powershot A75
- Powershot A80
- Powershot A85

Instructions

If your camera is still under warranty, the best thing you can do is to take it to the nearest official Canon repair shop and Canon should fix it for free.

If your camera is out of warranty, or if Canon refuses to repair it for free (happens sometimes if for example they suspect the camera has not been treated properly) you can try some of the methods listed here to repair it yourself. These simple methods have helped a lot of people fix their cameras.

Before trying any of the suggestions, make sure your Canon has fresh batteries and it is in recording mode.

1) Remove the batteries from the camera, wait for a couple of minutes, then put them back in and turn the camera on.

2) Try compressed air. With a fine tip blow off gun and dry compressed air (20 lbs) set the tip between the lens turret and the camera body and turn on the air while moving the tip around the lens. It should remove all dust and sand. Turn the camera on and it should function fine.

3) Another method is to tap the padded USB cover part on a hard surface, for example, a desk. It sounds so simple, but very often in works.

4) Try forcing the camera lens:

Turn off the camera. Place it on the back with the lens facing up and take a look at the spacing between the lens and the lens housing. If you notice that the gap is not even all the way around the lens, the problem should be easy to fix. This type of a problem usually occurs if the camera was dropped while the lens was extended.

Simply - VERY GENTLY - press down the lens on the side where the gap is the biggest. You should hear a "click" as it pops back into place. Try powering the camera back on.

If the lens doesn't extend at all or it extends, and then retracts again, do the following. Turn the camera off. Take the camera in one hand and with the other gently take one part of the lens and gently move it round in a circular movement. Do so with both sections of the lens. You will hear a "click" as it pops back in place. Power the camera on.

Another version of this fix would be to pull and twist on the largest ring of the lens while turning the camera on. Listen for a "click". If at first the focus seems to be off, turn the camera on and off and take lots of pictures, close ups and distance. Focus should slowly start improving.

5) If that doesn't work, there is an online guide for dismantling Canon cameras and fixing the E18 error. (NOTE: Try this only if your camera is no longer under warranty!) It is a great guide with pictures and it can be found here.

There are 2 other guides, one Bulgarian and one Estonian with the take apart procedure for Canon cameras. They are not in english but have a lot of pictures which help with the process.

Have Canon PowerShot A80. New batteries, turn on and it automatically turns off with a buzzing/clicking noise... Window shows error E18


The E18 error is fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension.

Here's some things that you can do to try to correct it. They only seem to work for about 40% of lens errors, but if the camera is out of warranty they're worth a try:

My camera says lens error when i turn it on


Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...

Here's some things that you can do to try to correct it. They only seem to work for less than 50% of the lens errors, but if the camera is out of warranty, they're worth a try:
