Question about Canon PowerShot A640 Digital Camera

1 Answer

Powershot A640 Could Not Be Powered On, Burnt Smell My Powershot A640 died during a picture shot, lens remaining open. I thought it may be due to the dead batteries. But after putting new batteries and pushing the on/off button, the on/off indicator blinked once then shut off by itself. After a while, a strange smell came from camera batteries area, and I could feel warm there too. Immediately I took out all the batteries from camera. When checking the posts here the other day, I tried one solution and got the lens back to close: first took out the memory card from camera, then put the new batteries in; push the on/off button with no memory card. I found the lens retracted a little before camera shut off by itself. I pushed on/off button three times to get the lens fully close. However, the burnt smell came out again. I immediately took out the batteries. Did I get a short circuit inside? Is there any ways to fix it?

Hello

The problem is that the lens has become stuck in the barrel after dropping it. There are some DIY solutions you could try, but the probability is that you will have to get it fixed by a professional.

Use these at own risk as it may further damage the camera.

Firstly , try connecting your ac adapter or usb cable.

Try holding the shutter button while switching on the camera.

Look at the lens , and if some of the lens 'circles' is misaligned or not concentric then try wiggling it (while holding camera lens down).

Try gently pushing or pulling the lens when it extends but this is risky as it may cause the lens barrel to slip out of its guidance system.

Another way to do this is to place the camera lens down on a hard surface and then power it up. Be sure to use a soft cloth or something similar as to not scratch your lens or casing. Let the lens push the camera up and down a few times and sometimes the little resistance provided by the camera is enough to get things going again.

Try hitting your camera near the lens on the body with the soft tissue on the palm of your hand.

Other than that , I would take the camera to a repair center for a evaluation to see if it would cost more to repair than to replace the camera.

If it is still under warranty I would suggest you take it in before trying any of these steps and remove any off-brand batteries or accessories as some stores are really fussy about warranty repairs on camera's with non-brand accessories.

Hope the advise is useful.

Regards
Andrea

Horizontal white lines on blurry still pictures - after 2 years. But the video is working properly.


Dear Friend,
I had also the same problem with my Canon A430. Mainly this problem is due to stuck of the camera shutter, always in open mode, images are overexposed due to this.
I had the problem with lens flex cable, which was partially damaged due to movement of lens and one coil was not working, due to this one shutter was not working and remains always in open mode. There are two coils, which operates the 2 shutters. I purchased the lens flex cable from ebay and replaced it, now it is working fine. Your problem may be the same.

My canon powershot A640 wont turn on despite having new batteries installed, also the USB connector socket has fallen inside the camera, will this cause a short that will stop it powering


Yes, you are probably right. A short within the camera could make it "un-startable. Take it to a local electronist or a Canon dealer and they will help you solve this problem. Also check if the batteries are good and fully charged. Some new batteries could be faulty from the factory.

Camera works but the screen went black A640 except for video and color swap. Did I press a button? I was shooting in cold weather.


Think that you might have accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the LCD display on and off to save batteries. You would then use the optical viewfinder in its place. To turn the screen back on, just press the DISP button one more time.

But if you've already tried this, have you also tried downloading any of your photos taken with the black screen to your computer? Are the photos also black? If so, you might instead be experieincing a stuck shutter (possibly due to the cold weather).

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).

To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see this link for further info and a simple fix that may help.

Canon PowerShot A640 lens problem


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 are 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.

Lens error, Restart camera


This error message is displayed when a malfunction occurs in the lens. Sometimes it can be a manufacturing fault other times it may be due to a grit of sand in a gear, or damage to a barrel. The only remedy is to have a service centre inspect it for you. It is most probable that the lens will need to be replaced. Good luck!

One thing, you mentioned that the lens error occurred after you wer able to take a good picture. This really sounds like your battery ran down during shooting, and did not have sufficient power to properly shutdown the camera. Focus on your battery as the potential cause first. Note that if the battery is older than a couple years, it may be time for a new one. Rechargeable are not meant to last indefinitely.

Black screen on my Canon PowerShot A640


I had this problem too. Try the "DISP" button (bottom left on the display side of the camera. It allows you several viewing options, and is easy to accidentally hit and turn the LCD screen "off."
