Canon Powershot A590 IS Troubleshooting
The Canon PowerShot A590 IS is an 8 megapixel digital point-and-shoot camera. It comes with a 4x optical zoom with an image stabilizer. Pictures are viewed on the large 2.5 inch LCD screen.
When you press the on button the camera will not turn on.
First, verify that the batteries are installed correctly (or installed at all).
Assuming the batteries are present and installed correctly, a common problem is that the small white button inside the battery compartment is not being depressed. This sends the camera a signal that the battery cover is still open, and it will not turn on. The problematic button is to the right of the memory card slot in the picture. It is a small white button the size of the top of a toothpick that is pressed by a piece of plastic on the battery cover.
Solution: If this plastic tab is broken, then the button is probably not getting pressed. To fix this, you can superglue your own home made tab onto the hatch. A toothpick works well for this fix.
Another explanation for a non-operational camera is the battery contacts are dirty, or are not contacting the batteries whatsoever.
Solution: To fix this, clean the contacts on the underside of the battery hatch, close the hatch and see if the camera works. If the camera still doesn't work, then try putting something under the contacts to facilitate their contact with the batteries.
If all else fails, try to pull the -'ve connector right out of it's slot, to make a better connection between the connector and the batteries. See details at http://lakeuk.blogspot.com/2010/04/camar...
==== My Camera Lens Doesn't Work, or It Says "Lens Error, Please Restart" ==
When you turn on the camera the lens does not work, or a lens error message appears on the screen.'Len is not going back to its place. It remains out.
One of the most common problems is that the camera batteries are low and don't have enough juice to extend the lens.
2) Put in fresh batteries and remove the memory card Turn on the camera. You will get an error message saying "no memory card". Turn off the camera, and insert the memory card. Restart the camera. This may fix the problem.
3) Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Because of this, extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particles that may be jamming the lens assembly.
Another problem is that sand, dust, or other grit have entered the camera and are preventing things from moving smoothly.
1) Use compressed air to blow in and around the lens barrel. This will hopefully remove whatever grit or particulate matter that is causing the jam.
The worst case scenario would be that the lens assembly has become dislodged from its guide slots when it was dropped or when it experienced some other sort of trauma.
Solutions: There are a number of ways to attempt to re-seat the lens guide pins in their slots.
1) Place the camera flat on its back on a table, pointed at the ceiling. Press and hold the shutter button down while at the same time pressing the power-on button. The idea here is that the camera will try to auto-focus while the lens is extending, hopefully seating the lens barrel guide pins in their slots
2) Repeatedly hit (with moderate force) the side of the camera against the soft part of your palm. This could potentially knock the guide pins back into their slots. Be careful here, as knocking the camera too hard could damage/dislodge internal components.
3) If the lens assembly looks crooked, try wiggling it gently while it is extending. Listen for a 'click' noise, indicating that the guide pins have reset in their slots.
When you turn on the camera a "No Memory Card" or similar message appears on the screen.
If your memory card is locked, then remove the memory card from the camera. On one side of the card, there should be a switch that can be moved either backwards or forwards. If you receive the "memory card is locked" error message, then move this switch to the opposite side and see if the problem is fixed.
If there is no memory card installed, then you need to go to the store and buy one or order one online.
Either reformat your memory card, if possible, or go to the store and buy a card that will work for your camera. Memory cards are cheap, and available at a great variety of stores and online.
