As far as I know it is less expensive to replace than to repair, but if you really like the camera, try Canon repair service or live chat weekdays: http://www.usa.canon.com/cusa/consumer?pageKeyCode=onlineRepairLanding#
You can thank me by joining me at http://outsideshooter.blogspot.com

Take a look at these useful articles. Truth be told if the camera is under a year old take it back to where you purchased it and see if they can't get it sent out to be fixed. If you have no warranty on it you will likely want to try one of the methods in the articles below or buy a new camera. As sending it out to get any of these repairs done generally costs more than the camera is worth.

Sorry, missed your previous posts. The following blog outlines some simple 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. Hope they help:

Wish you the best of luck. But keep in mind though that you have a 50/50 chance of repair with the above techniques. If they don't work, the camera likely needs replacement of the lens assembly. Unfortunately, due to the complexity of the repair (a LOT of things in the way), the cost of such a repair usually outweighs the value of the camera.

The following two links are repair guides for fixing a cracked LCD on similar SD500/600 models. They include some photos that may help illustrate how deeply buried the lens assembly is in the sd elph cameras.
