My Canon G6 camera just stopped turning on 2 days ago. It had been functioning normally previously. I turned it on in camera mode, the lens extended, but no image was visible on the screen. The power seemed to be on, but I couldn't change to to picture review mode or get the lens to retract. I also couldn't get the camera to turn off. I removed and replaced the battery, but then the camera wouldn't turn on. Even after fully recharging the battery, the camera will not turn on or show any signs of having power any longer. Any suggestions on what to try?
