Power failure My Canon G9 won't turn on. I keep reading this is common to this model. How can I get this fixed for less than $150?

Yes it is common on the G9 and also the G7 models. It's from loose screws inside the camera. The best place I know of for this problem is camerasandparts.com They have a thing on their site for this problem where they service the camera, fix the problem and do the correction so it doesn't happen again in the camera. They're the best if you need help with a Powershot, that's all they deal with. They charge $89 for everything with the shipping back included. Hope that elps, that's the place if you need help with a Canon Powershot Camera.

Things to check first for a camera that won't turn on are battery contact points, and micro switches that are located on the battery and memory card doors. Troubleshooting tips on other things that need to be checked may be seen here. These tips won't work for every case, but they're worth a try.
