My Optio33LF worked fine until a few days ago. I was in the middle of a hike, took a picture, and a few minutes later tried to take another, but none of the buttons were functioning (including the shutter release, menu, and function buttons).
I turned the camera on and off a few times, replaced the batteries, replaced the memory card, and still nothing. However, if I turn the camera on in playback-only mode (with the lens closed), all the buttons work fine.
As far as I can tell, it didn't get any water in it or take any unusual bumps. Any thoughts on what could be causing this and if it's easily fixable?
