I have removed the three screws you mentioned, but not the pin screw or the circular switch which is the lock switch for adjusting ASA. My problem is that the ASA setting doesn't respond to change when pushing up on the lock switch screw and turning the wheel beneath the lens housing. I found that after removing the single screw on the left side and slightly pulling up on the top plate the ASA setting would respond to procedure. But there is something in a bind here and I think the only way to solve it is to remove the top plate and have a look. Thanks again...
