MY Z612 HAS GRADUALLY BEGUN TO TAKE DARKER AND DARKER PHOTOS.

THIS CAMERA WAS WORKING FINE, UNTIL VERY RECENTLY WHERE I NOTICED A GRADUAL DARKENING AND FUZZINESS TO THE QUALITY OF MY PIC'S. AT THIS TIME, IT HAS GOTTEN SO BAD, THAT IF I AM NOT SHOOTING IN BROAD DAYLIGHT OUTSIDE, OR WITH EVERY SINGLE LIGHT ON, THE CAMERA'S PICTURES ARE BARELY VISIBLE. I BELIEVE THAT THE FLASH IS NOT WORKING, BUT DON'T KNOW WHAT TO DO. PLEASE HELP.

What I would say normally is that its your ISO settings that are changing, but unless you physically go and change them, they should not change themselves. So, I think its actually a probably with the physical properties of your shutter, what exactly I'm not sure, its really hard for me to make a guess without looking at the camera, so try taking it in to a camera repair shop to get a diagnosis and a quote, which is usually free. The other thing I would recommend doing is going in to the settings and turning the ISO down , then taking the photo to see if anything changes. This should normally correct the problem if all the physical stuff of the camera is working correctly, but I don't know if thats the case. Hope this helps.
