Reassembly of the lens of my canon sd300

The model indicated does not have a "bulb" as it uses 3 picture tubes.

Examine the picture with color set at zero---stand back and look= if the screen has a mostly yellow (all or part of the screen) you have bad Glycol in the blue picture tube(if need explanation ask) and a look in the lens of the Blue tube will confirm this.

If able with back off and a small mirror look in each lens--red picture, green picture and blue picture.

If the Blue looks like a floodlight with little or no image--bad glycol in that tube.

Hi

The Canon E18 error happens when the lens gets stuck while trying to extend. When your camera was dropped the lens mechanism was damaged resulting in this error for a jammed mechanism.

If the camera is still under warranty you should see if Canon are willing to repair it. If not you can view this link which is a very good walkthrough with pictures on how the error was resolved with a Canon SD300.

As you can see from this the process is intricate enough and involves opening the camera so should only be attempted if you feel confident about taking it on.

Hope this helps. Please remember to rate my answer. Many Thanks.

hi innasha,

try the following:

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 drycompressed air (20 lbs) set the tip between the lens turret and thecamera 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 shouldfunction 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 veryoften 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.

there is a guide to dismantle it with pictures: try it:

Hi, i have provided some disassembly and reassembly detail on my blogsite to deal with a loose lens problem. The site has a link to the service manuals which might help, otherwise my detail might be all you need. See: http://howtheheckdididothat.blogspot.com/2010_10_01_archive.html There are lots of pictures and step by step instructions. Hopefully this will fix your problem.

The following blog outlines some repair options for a lens error. They won't work for all cases, but they're worth a try if the camera's no longer under warranty:

Not quite sure where you are having the problem with your camera, but there are several places on the internet that can help fix your camera and/or lens.

Here is one listing I found on eBay for you - http://cgi.ebay.com/Canon-SD500-Camera-LENS-BARRIER-SHUTTER-FLAPS-REPAIR_W0QQitemZ260164183646QQihZ016QQcategoryZ64352QQcmdZViewItem
You can email him your model number and he should be able to help you.
Best of luck!

I need more information to help with this problem. What model is the camera? Is it a single-lens reflex camera, or a camcorder? The more details I can get, the better I will be able to research and recommend solutions. Thanks.

Your first problem sounds like a defective CCD imager. If your camera was an S300 Canon should fix this for you for free, including free shipping both ways. Please check the following two links for more info:

http://www.usa.canon.com/consumer/controller?act=PgComSmModDisplayAct&fcategoryid=225&modelid=13390&keycode=2112&id=29819
Applicable cameras include:
A40, A60, A70, A75, A80, A85, A95, A300, A310, S1 IS, S60, S200, S230, S330, S400, S410, S500, SD100, SD110

Unfortunately, you mention that your camera is an SD300. That model camera is not currently on the recall list. But you might want to call Canon anyways. You might get lucky as the problem sure sounds familiar to the recall (excuse me, advisory hehehe).

As for the SD500 with the E18 error, try http://www.e18error.com/repair.html

pretty easy to replace the screen, i suggest buy SD300 from ebay that has lens problem, but it is known for sure that screen is working, you might find one for $20-30, also look for SD200 you might find it cheaper and it uses the same screen as your SD300

Your CCD is damaged, OR your aperture is stuck closed in your lens. Turn on the camera, have the lens extended and look into it, do you see a small circle at the bottom that looks like an opening? If not your aperture is stuck and you need a new lens. If its open, your CCD is bad and needs to be replaced. www.darntoothysam.com
