Question about Canon PowerShot SD300 / IXUS 40 Digital Camera

Canon sd300 lens noise

When I turn the sd300 on and off it makes a gritty (grindy) sound. It sounds like it is in the lenses that come out. Is there any way to fix this or will I have to take to a camera shop? I just bought this camera from someone and if it is unrepairable or may not last much longer I need to get it back to them asap. Any help would be greatly appreciated.. Thank you

Defective mechanism, You need professional service to fix it, or better give it back asap,  digital camera lasts only for three years working at its best form, I suggest you buy a brand new one and sell it after two years of use. [:0)

My Camera's battery is fully charged, but when I try to turn it on, it makes a noise, lense opens a little bit and screen flickers a small bit? Any ideas?!

It sounds like your lens is out of alignment and dragging. Check to see if there is any debris caught around the edge of the lens. Other than that, a repair or replacement may be necessary.

Camera shuts off after E18 error code

You have most likely dropped the camera or banged it against something while the lens was out. This situation causes the brass pinion gear to shear teeth off the plastic ring gear on the Inner Lens Housing. It may also cause the guide pins to jump their track. If this is the case the repair bill usually exceeds the value of the camera and you are probably better off selling it for parts on eBay and getting a new higher resolution camera.

Lense won't extend. Has error screen that says "lense error, restart camera"

sounds drastic but turn on cam and grab hold of lens to try to fully extend it manually. if you hear a crunching noise that means the gears are stripped. not worth repairing

Canon sd300 cant see pictures taken

This may sound silly, but did you check the shutter on the end of the lens when the camera is on to make sure that the shutter is open? Sometimes some dirt or sand can get into the lens barrel and make the shutter get stuck in the closed position. If this happens, gently open the shutter with a a toothpick or something (NOT your finger because of the oils and NOT something that will scratch the lens).

If the shutter is open and the pictures turn out black both on the camera's LCD and on the computer once you download them, then I'm guessing something happened to your CCD, which is the tiny electronic chip that records the light coming through the lens. Either something inside the camera has fallen in front of the CCD and is blocking the light (unlikely) or the CCD chip has died. If that's the case, I hate to say it but buying a new camera would be more cost effective (and probably cheaper) than getting it fixed.

Canon Ixus 40

This can be caused by several different situations. Most commonly the camera has experienced some kind of impact which knocks an element out of alignment, preventing the lens from rotating normally. Symptoms of this include: *you may hear no mechanical sound at all when the camera is turned on *you may see visibly mis-aligned components of the lens *you may hear a loud "snap snap" sound as the camera tries to move the lens when the camera is powered on The second most common cause is a particle of sand getting stuck in the focus motor drive gears. This prevents the focus element from moving normally and causes the camera to shut off to prevent damage to the lens assembly. Symptoms of this include: *A loud "buzzing" sound when the camera is turned on, followed by the beeping and shutdown. Finally the third most common cause of this problem is a broken tooth on the zoom motor drive gears. Symptoms of this include: *the sound of the running motor with a regular "click click click" sound for several seconds. This will not be a "snap snap" sound, that is a different problem. *the lens will move in and out easily by hand as if free from any resistance. All of these problems require disassembly to repair. The charge is around $125 labor at my shop.
