I have a problem with my Minolta srt 101. When I press the shutter button, the mirror flips up, but stays up. The curtain does not move, and you have to crank the film advance to lower the mirror. Any suggestions? |

well, SLRs operate like dominoes... the FTb that i picked apart operates like this:
1. press shutter button
2. diaphragm activator stops down aperture, random lever flips up mirror
3. levers connected to mirror move yet another lever and release 1st curtain...
i'm guessing yours works in a somewhat similar way, poke around, you might be able to find something. |

I may be misunderstanding you, but does your shutter fire at all? When you say "the curtain does not move" I don't get what you're referring to unless it's the shutter, and if that's the case I don't see how you could crank the film advance. The whole thing is just as Dragunov says, it operates like dominoes and if the shutter didn't move, the rest of the sequence just wouldn't happen.
In case I misunderstood, the shutter is firing and the mirror just won't come down, this is a common problem for older SRT cameras that have sat for years and can sometimes be fixed by lubricating the mirror kick gear. If you remove the baseplate, there's a large white plastic gear with a tab which spins when the shutter is tripped, after which the tab hits a linkage at the end of shutter travel which causes the mirror to drop. A small drop of light oil on the pivot can sometimes remedy this problem, but if it doesn't, the camera needs a CLA. There are more extensive things that can be done, but I wouldn't recommend them to someone with no camera repair experience. |
