Ive had my SD850 for a little over a year now. i've dropped it a few times but its never been in water or touched water and its always seemed to work fine. it was working fine this morning, and all of a sudden this afternoon the power button stopped working--i'd have to press it a lot of times for it to turn on, and then i had to do the same to turn it off. i'd even take out the battery and put it back in and it would still be on. now it wont even turn on at all. my battery's charged and working, and its clean and everything. everything else besides the power button works fine..

Re: camera wont turn on or off
Sounds like the power button switch as been damaged... if I recall correctly it's a very small button and even a small amount of damage to it will cause the parts to no longer align properly which will result in the outer button that you push not reaching the inner button on the board of the camera.
One solution would be to open the camera and see if you can see anything obviously wrong with the button on the inside of the camera. The button is part of the flash assembly, so if there is damage to it replacing the flash will probably solve all your power issues!
If we can help with the part or do the repair for you, please let us know! We pride ourselves in AFFORDABLE digital camera repair... watch out for those ... 'geeks' they will want $150-200 to repair this problem as all they will do is send it to Canon and they will repair it for a flat rate of about $120+.
If all you need is the flash, I can get you one, new or used. New will probably be $40, used $25. If you want us to install it, the cost would only be the cost of the part plus $25 for the installation and return shipping.
Good luck with your repair, and even if you don't need parts from us please let me know if you need any more assistance.

Don't play around with that lens, you can do more damage to the camera and focus with some of the stuff people tell you to try. Your camera just needs to be serviced and you'll be working great again. The shop that specializes in service for the powershots is: camerasandparts.com They're amazing if you need a hand with one of these, that's all they deal with. They have your exact SD850 Lens Error, Restart Camera problem on their site. Good luck, they're the place for help with a powershot, best of luck with it.
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 ...
Unfortunately, many cameras that fall prey to this can only be corrected by professional repair. But, here are some things that you can do that may correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty, they're worth a try.
Unfortunately, there are several parts that may be damaged with water. It doesn't matter if it's already dry. Water contains lots of minerals and other material that are conductive. Once the water evaporated, the conductive materials stays in the electronics.
As you have a broken camera anyway, you can try:
* Using a hair dryer, blow some hot air (no the hottest level) inside the camera. protect display away from the heat.
Take a look at the suggestions at the top of page 122 of the Advanced Camera User Guide. The suggestion is that the cause may have been that the camera was still on when the memory card/battery cover was opened. Try closing the cover and then turning the camera off and then on again. Hope this helps.
There could be a number of reasons for the lens error. ie. . sand in camera, impact damage etc. Typically the lens can be dissasembled and repaired by a competent camera repair technician. If you are certain that you did not damage the camera in any way I would send it back to canon for a warranty repair. If you however think you could have damaged it you are probably looking at around $100 to repair the camera. Hope this helps!
what you are seeing is a generic message that means there is
some sort of problem with the lens, it could happen in many different
ways such as sand or dirt in the lens gears.
If your camera is less than a year old, please call Canon and have them fix it under warranty!
If your camera is more than a year old and out of warranty, a couple solutions would be to either buy a defective camera online and
make one good camera from the two if you can do that sort of thing
yourself, or secondly have it repaired by somebody.
trying to send the camera to Canon for repair out of warranty (though you can call them and verify
what I'm about to say) because they will want $150+ to do the repair
for you. Parts are not cheap to buy from them.
I know of
one very affordable digital camera repair business... because I own it.

Ihave the same problem. Its annoying. When you turn it on does it make a buzzing noise? Cause that's what mine does. Except I never dropped my camera. It just goes to the Polaroid screen and then turns off. I'm wishing I wouldve bought a different camera :( Sorry I can't help..
