trouble with my c-2020
just recently I've been having a little trouble with the lcd screen , it sometimes seems slow reacting to movement and looks like it's not picking up enough light (maybe aperture problem?). and some pics come out very dark or almost black. also, between battery changes the date and other settings like all reset, ft/m, auto file seem to reset to defaults. I'm wondering if this could be an internal power source problem, but I am not sure if this cam even has one.
any advice on this subject would be greatly appreciated as this is a great little camera when it's working properly and i'd rather not have to go and buy a new cam.
