I might just take it to a camera shop or something, but figured I'd ask here first.
I have a Sony DSC-S60 digital camera. When I put the selector in a mode that allows you to take pictures, and try to turn on the power, it makes the startup noise, then shuts off immediately.
If I turn the selector to the mode that allows you to review stored pictures, it works perfectly fine. It starts up, I can view my previous pictures, mess with them, whatever. If while the power is still on in this state, I shift the selector to a picture-taking mode, it shuts off as soon as I turn the selector.
It's not full of memory (it only has one picture), and the batteries are brand new (even the battery life icon shows a full one). I really don't know what else the problem could be.
