Canon Ixus 40 corrosion

I did not turn "On" my IXUS 40 camera for at least 6 moth,I used it only several times.When I tried to do so, the camera did not turned on. I have still waranty for this camera. The lab expert told me they cant fix it because
corrosion inside the camera and the reason the camera is "dead". The camera was always in the closet and never become wet. Is it a known problem in this kind camera, or is it a problem only in my camera

Shall apriciate to get your opinion in this problem.

Re: Canon Ixus 40 corrosion

Here are some simple things to try first for a camera that won't power on. They won't work for every case, but they're worth a try:

I can take photo.. but i can't see it.. display problem. how much it will cost? ixus 8515

Cost of repair would be probably more than the camera is now worth. But is the screen just showing black? An issue with the tiny SD10/20/30/40... cameras (IXUS versions also) was that sometimes a little corrosion could form on the A/V plug switch that would in effect simulate the plug being inserted, thus turning off the screen. If you have your television video plug available, try inserting and removing the plug in its A/V port a few times. If this is the problem with your camera, sometimes this helps remove that corrosion, setting things right again.

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.


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
- Powershot A95
- Powershot A400
- Powershot A410
- Powershot A430

- Powershot A620

- Powershot S1 IS
- Powershot S2 IS

- Powershot S10
- Powershot S30
- Powershot S40
- Powershot S45
- Powershot S50
- Powershot S60
- Powershot S70
- Powershot S80
- Powershot S400
- Powershot S410
- Powershot S500

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.

- Estonian guide

My camera wont start, at all!

Could be several reasons, but just make sure the battery door is fully closed as there is a switch on the door that musr be closed. Other than taht, camera will need to be serviced.

LCD Scree went blank/black

No problem. Discovered that fix by accident when my camera did the same thing. Since the screen was blank, tried arranging camera setting using the camera's AV cable with the TV, and discovered that fixed it. Apparently corrosion builds up on the AV cable plug switch (which also turns the screen off when inserted), and inserting/removing the plug several times can fix it.

Lost charger

No you can't. Recommend just buying another charger. Generic NB-4L chargers are relatively inexpensive ($6 to $10). So are the generic NB-4L batteries. Here's some chargers from Amazon:
