Yashika GSN hard shutter press

[bmarkmain]

The GSN I have seems to work, but have not run a roll thru it yet. However, the shutter release has to be firmly pressed down way past the normal half-push which activates the f stop indicators, in order to trip the shutter. Sometimes too hard, I fear for the steadiness of the camera. Is there an adjustment for this?

You can make minor release adjustments with this screw...

Is that under the shutter release itself? 😕

BTW, I think your album pictures are great!

Well, those of us that need help with the mechanics sure appreciate you spending more time working on them!! 🙂 I'm just a hack but I know what I like - you should try to spend more time exposing film!

Already posted in your b'day thread but, Happy Birthday to ya! 😉

Thanks greyhoundman. A small adjustment should do it. I'm going to run the rest of this roll thru it, see how they come out, and go from there.

Just a thought - I have seen this on cameras where the bracket at the bottom of the shutter rods has been knocked out of alignment (or bodged by a klutz). Could it also be that there is a P.O.D problem lurking here?

John, What is a P.O.D. problem?

 

[bmarkmain]

Thanks, I realized it later when browsing another thread.

My first thought based on my last disasterous attempt at repair of another camera was it meant "Personal Operator Destruction" or something like that.

Hi,
I just fixed an old yashica GSn. but something is funny about it. I have to press the shutter release for like 2 seconds to get it to rlelease the shutter. This release time is shorter for higher shutter speeds like 1/250,1/500. but its definitely 2+ seconds for lower speeds. I am suspecting pad of death. I tried adjusting the screw that greyhoundman had mentioned in his previous post. but that doesnt change it.
Is it pad of death? or sometghing else?

thanks
Amit

The pad is the first place to look - do you get the Yasicka "click" while you wind on? If not the pad is shot. If you do, and the pad is OK I would suspect that hte timing capacitor is not charging correctly, but you can't check that without a good pad.

My GSN problems/solutions

My GSN problems/solutions

On my repair of my GSN, there were only two things that were amiss, the fact that I had to press very hard to get the shutter to release at all, and I had no lights or battery check. The lights problem was a disconnect on the solder at the negative terminal of the battery compartment, which I re-soldered after removing the top plate of the camera, somewhat microsurgery, however.

The second thing I did was unscrew (counterclockwise) the slotted shutter release rod, thinking that getting it closer to the push plate on the finger rod, would be the thing to do. I of course then put everything back together, and the shutter would not release at all. My POD was nearly new condition, so that was not the problem, however on my next attempt I screwed the rod in (clockwise) and that did the trick. The shutter released properly when I put everything back together again for the XXX time.

Might be worth a try, as the POD replacement is no piece of cake.

Get an old camera to work on before trying the POD replacement on your good camera, is my recommendation.

hey bmarkmain,
Perfect. I rotated the little screw clockwise and shutter release is normal 🙂 My Pad looks good too. so I wasnt sure what was happening. So, what could be the reason though? this little screw determines resistance in some circuit? I am totally going out on a lam. I havent looked the electrical diagrams yet.

 

[bmarkmain]

Good job.

Good job.

Amit,


Glad it worked for you. I think the adjustability of the rod, with the screw, is something that was engineered into the camera. I did not go into the whys of it, just thankful that it worked. Possibly some of the technically proficient members will comment on this. I am impressed with the camera, its build and looks, and capability. I am working on a roll right now, and will upload some of the shots when done. I am still adjusting to the sighting thru the viewfinder, as it is not as easy to focus as my SLR, I just don't see as well with it.
