Hi, I just bought a secondhand canon G12 camera? It’s not working properly, after few seconds will show error - a camera error was detected. Will shut down automatically. And also when I rotate the LCD screen and push down screen on to the camera (screen facing me). the screen becomes blank, I think the screen unable to detect when I rotate the screen. Anyone knows where I can bring to fix it?

Is there any error code that shows on the screen? That might be able to zoom down on where to look for the problem.

This message will appear. E32

Found this on the internet... maybe something is blocked between the lens barrel.

This is apparently an error with the focus mechanism. Sometimes using some compressed air for electronics around the lens barrel will clear up the problem, but it could be some dirt got in the gears and may require the camera to be opened up...
