Why does Canon SD450 camera power off after a few seconds?
My rummage sale Canon SD450 came with the lens extended. After fiddling with it a few minutes it was able to retract the lens and close the cover. At home, I put in a Sandisk 128MB multimedia card and charged the battery.
When I powered up it extended the lens and I was able to take a still shot and a movie and display them. The zoom function worked, but with some roughness.
Now it is stuck with the lens extended and will not stay powered up or function in any mode. It powers down after a few seconds. With the mode switch set to play there is a brief display of a Canon startup image of a bird, then it powers down. If I press the power button while holding down the center select button I get an animated digital display of the clock time, and pressing the left or right button changes the background color of that display. No other button presses have any effect. Then it powers down.
There are no error messages or warnings. There is no display when I power up in either still or movie modes, there is a brief motor sound, and then it powers down.
I suspect maybe the lens mechanism is jammed in the open position, and that the controller senses the jam and automatically powers down to protect the system from overloading the motor.
Anyone else know about this?
