I, or my parents, have owned this camera since it was new. I have used this camera for years without any problems. Until now. The meter does not seem to adjust the shutter speed. The needle inside the viewfinder mves in accordance to the light changes, but the shutter speed stays at whatever it was set at. E.G. I am taking a shot in bright light with ths film speed set at ISO 400 in Auto mode. The shutter speed is set at 1 second, which should not matter. I bpush the button and, voila, the exposure is one second long. What is wrong? Can it be fixed?
