I have an XG-7 that has a flaky meter that does not turn on all the time. Also when the shutter is pressed the mirror stays up and the shutter stays open until the power is switched off and then they close. On the B setting the mirror and shutter seem to work properly. Can anyone help me with this problem?
It's usually caused by dirty variable resistors- aperature-value, film-value, shutter-value, etc. Search this site for the keywords "minolta resistors" and you are sure to find some info.
