today i was replacing a battery in my canon powershot sd750 when it accidentaly fell into my dog's water dish. It was only partially filled and i managed to pull it out within 10 seconds. I removed the battery and dried the outside and as much of the inside that I possibly could. Then, i turned it on and the lcd was simply not bright enough to see. It would flash on and off with brightness levels. I let it dry some more and now the lcd wont show up at all. is there anything that I can do to fix it, or is it ready for the garbage? Please help me to figure out what the problem is, because I love this camera!!

Unfortunately with water damage the camera may work for a few days or even weeks after you first dry it out, but then it will stop working completely. If you have corrosion from water exposure then the camera is gone, it's not worth trying to fix. Even if you replace the main PCB it probably has damage to the lens, LCD screen and flash as well.

You would need to take out all moisture
trapped in the camera: Dry the camera, battery, any accessory, etc. with
cloth and wrap each piece, camera and accessories, in
newspaper. Place a few handfuls of rice into a plastic bag and then place
the wrapped camera in the bag with rice. The newspaper wrapping avoids
direct contact of rice
with your camera because the dust from the rice can get into the small areas of
the camera. The newspaper and rice will absorb moisture. Leave it there (with
the bag open) at least 24 hrs.
Hi There are several things that could cause this.
1- Check the battery door indicator switch under the battery door and beside the memory card slot. Is the little black switch damaged or missing? Try pressing down gently using a pen it with the door open and then press the power button. Does it turn on?
2- The fuse has blown and needs to be replaced. Offhand I don't recall where it is on the SD750 PCB or how hard it is to solder on a new one (depends on if its tricky to get at or not). Good thing is fuses are really cheap.
3- Other power problem with the PCB due to corrosion or impact damage. The PCB or 'motherboard' of the camera will need to be replaced.
My guess is that you damaged it by inserting the battery prior to properly drying the camera. Chances are that you shorted something out when you powered up with water still inside the camera and if that is the case I would suggest placing the camera in a sealed bag/tupperware with some dessicant (a material that removes moisture form the air) and the battery compartment left open (and the battery out). Try powering it up after several days, I doubt it will work, but it won't hurt trying. Then call Cannon to see how much it will cost to get serviced. DO NOT MENTION ANYTHING ABOUT DROPPING IT IN WATER. Just say it stopped working one day. I really suggest using a dessicant because if they open it up to fix it and find any noticable water, you will be SOL and it won't be covered under warranty.
