I just bought PEN-EE from junk market for 35 cents. The is physical and overall condition is good but has following problems and want to repair that myself. The issues are:
1) Less than 22 value aperture is always open, no matter what.
2) The shutter doesn't come to shut position after shutter release button is pressed. Instead it comes in the shut position after the film is advanced.
3) When - from the dial - the ASA is selected the film does advance but shutter release button doesn't work.
----
A) Please let me know how to open the shutter.
B) I don't know how aperture and ASA settings work together.
