Great advise guys. Worth trying if you haven't.Sounds like a contact issue causing loss of power... clean the contacts on the battery tray as well as inside the camera with a pencil eraser.
Just bought one and have the same issue with battery compartment not staying tight and loosing connection.Anybody else experience their camera losing connection with the batteries and dying? Eject the battery holder out and slam it back in and it works again. Just pulled my camera yesterday and the last pic was over 3 weeks ago.
