I came across this shutter fix else where and am sharing here. worked for me.


First remove the plastic cone by using your finger nail at the positions marked by

the red arrows. This will reveal the shutter mechanism.


fix1


Next, loosen but do not remove the two screws indicated by the red arrows. This

will allow the shutter cock lever to be adjusted. The lever can slide as indicated

by the blue arrows. The screws should be tight so use the correct screwdriver.

fix2



Next adjust the position of the lever by trial and error so that when the film

winder is wound on, the rear of the silver piece is pushed past the shutter catch

by approx 0.5 to 1.0mm. Note the similar mechanism opposite (not shown in pic) for

the shutter close. The silver piece on that side should also push past the shutter

catch by 0.5 - 1.0mm. Don't adjust so that the silver piece pushes too far. If the

silver pieces do not latch on both sides of the shutter then the shutter will not

work. On the second film wind stroke the spring will cause the silver piece to

relax back and rest on the shutter catch. The copper springy parts are part of the

solenoid electrical circuit so must be clean and bright. Also no dirt or dust must

come between that part and the silver part. I tested that by placing a thin piece

of paper between the copper and silver parts and as expected the shutter did not

work. There are two solenoids, one for open and one for close shutter. The open

shutter solenoid actually pushes out causing the shutter catch to pivot inwards

towards the lens. That releases the sprung shutter and the shutter opens, which in

turn breaks the electrical supply to the solenoid (copper and silver bits

separated breaks the circuit). The close solenoid works in a similar way but it is

triggered later in time.

I have an EL which has developed the following fault: when I release the shutter, it stays open until I advance the film. Do you think your instructions might fix it?
Yimou 11 years ago
@ Chris1729, Does your EL has a button in front edge of hotshoe? If it has one , try to press it several times until it can reach a correct position.

id00092 11 years ago
hello there, i had a GT with the exact symptoms.
I followed the steps and finally i can make everything works
but the shutter blade did not open...
however i did notice the shutter show a slight "rotate" movement (for about 3 degree anti-clockwise at the first stroke and return to the original position after the "click").
did i miss something?
does it mean the shutter is sttuck or something else?

PS: battery should be ok because the meter is responding fine, self timer works.

Thanks for posting this! I just breathed new life in to my 35MB with this fix. The shutter cocking mechanism got out of alignment and on the second stroke, the shutter would reset. This meant I wouldn't get a battery check light, a light meter reading, or a shutter fire.
Dave 2008 Posted 11 years ago. Edited by Dave 2008 (member) 11 years ago
Bingo! Thanks fsixteen rule this is indeed, a very useful thread. As I have managed to get a 35GT back working again.

My camera had the added complication of a slightly loose lens, thus on the first stroke (of winding on) the lens would move ever so slightly and prevent the mechanism from completing it's full function. This meant no battery check, no shutter release and no light meter reading (as in orange.plastic case above).

I gingerly removed the four screws which hold the the silver film transporter/guide in position (seen in picture one).

This reveals the next 4 screws (3 of which are seen in picture one) which need to be removed.

This allows a metal plate and gasket to be taken out. Finally there are (you'd guess it) another 3 more screws, which on my camera were all loose and after being tighten up the lens was firmly attached to the camera body again, which made resetting the shutter a lot easier.
orange.plastic 11 years ago
Well, I thought it was fixed but now that I had a roll processed, only 8 of the 24 were exposed. It looks like the shutter is getting stuck randomly and isn't opening. The light meter is still working, so I know it isn't the same problem as before.

If I figure out the problem and how to solve it, I'll follow up with another post. This thread is one of the few places I've found online about fixing the Minox 35's.

thanks so much for posting this!
i have a minox 35 gl that i bought for a song from a popular auction site that i received a week ago.
i started the shutter repair late last week and just finished it today... yes, it took a while, but i'll tell you guys why. the screws holding the bracket for pawl (is that the right word?) were already pretty loose and i further loosened them and basically the whole mechanism came out of whack. also, the spring that is on the back of said pawl came loose from the bracket, and i wasn't sure how to put it back on. thankfully, my husband was able to put it back.
i just got everything lined back up tonite and tested it a few times and the shutter's opening and closing.
i'm not the first to say this, but this camera is a fragile little thing!
btw, i found excerpts of this repair manual after several google searches, it may benefit some:

Hurray, I shall proceed to worshipping the author of this so damn helpful article! I just bought a Minox 35 GT from ebay and everything seemed fine, but the shutter would not open. After the first shock and dissappointment I came across this and (listen up, peasants) although I am really (!) bad at everything concerning fine mechanics and stuff like this I was able to fix the problem with this great advice! The one lever that is supposed to close the blades again was not catching on properly so the circuit was not working. Furthermore you do not really break anything so go and try! Thank you so very much!!!!
dragonballyee 9 years ago
Awesome! I just got a Minox GL (1979) and put a roll through it. Sadly, only 24 of the 38 frames had images. But I went in and poked around like this diagram said and the shutter fires happily now. Awesome.

Spoke too soon. Something's wrong with the shutter still. Ugh. Meter works fine, but the shutter just won't trip anymore.

Seems like this worked for me. Only one strange thing... Sometimes the shutter fires right when I press the button. Other times it does nothing until I release the button. I've looked through it and it is working. It just seems random when it does one or the other.

I've just repaired mine. I then checked the collimation and it was significantly out. I ran a film through it last week and noticed the shutter failing to fire on a number of occasions. It will be interesting to see the results when I get the negatives from the lab.
I have adjusted the collimation and I will now be able to enjoy seeing tack sharp photos from this camera!

Bought my MInox35GT for $12 at a garage sale... Got it home and had some shutter issues and found this group and topic from a search when trying to repair it! I found it very helpful!
Thanks You!!

I found that when I would adjust the gap that after a few times winding and using it that the hammer would move back to the old position and the shutter would not engage...When loosening the two screws I accidentally took them both all the way out. When trying to put them in lost one of very small washers, which can be seen in 2nd picture. This actually helped keep the trigger mechanism in place when I adjusted the hammer. I removed the second washer and it helped hold the hammer mechanism in place. Hope this helps! Everything seems to be working... Now it's time to test a roll out in it!

I just fixed my Minox 35 ML the way it is described by the OP and can confirm that it works, even though the shutter assembly on the Minox 35 ML looks very different from the one shown in the pictures (GT). I just wish I had inspected the shutter *before* shooting a roll of film through it and giving it to the lab :-/
Bryan Rollins Posted 6 years ago. Edited by Bryan Rollins (member) 6 years ago
Confirming it works for the EL. It took me screwing up the other latch to figure out exactly how the mechanism was supposed to work in the first place, but i finally figured it out.

the solenoid on the left must have bent at some point and the spring was not connecting correctly on the first wind causing that latch to fail to engage at all. So, on the second wind, the spring returned to its normal place, not preventing the shutter from opening.

i used the screwdriver to extend the solenoid a bit so that it could make good contact with the spring. On the first wind, the spring connected with the solenoid and the latch engaged. i made the adjustment above with the two screws (which i misread as only adjusting the arm, rather than the piece of metal the arm was attached to. My screws were in much tighter than i realized preventing me from moving it at first). Thankfully after a couple tries at adjusting, on the second wind, the latches finally caught both springs and the shutter remained closed. Pressed the shutter release, and thanked this post.

Shooting at a shutter speed of 125 or below still feels suspect, but we'll see when the film is developed.

iaparkin 5 years ago
I have repaired two cameras - ML and GT - like this and both are still working after a couple of years. These cameras are used quite often as I generally have one or the other with me at all times. I'm a little paranoid about losing a film due to non-firing shutters, so I keep batteries in them and fire the shutters between roll changes and every couple of weeks when they are not in use.

Overall, I could see that it is very much YMMV and I just got lucky.

Have you tried to repeat the repair ?

Maybe try to readjust to the amount that you need to and then a little bit more for good measure. Make sure that the inner compartment is clean and there is nothing on any of the moving parts, etc

I tried the fix on my ML and the first time around it worked but at times the shutter would fire and the blades remain open.
I did the fix again adjusting the gap a little closer and now it works like a charm.
I am testing a roll...soon to see the results.

I am curious about the shape of the aperture blades....diamond shape but at f 5.6 looks a little skewed. Is this normal?
iaparkin 5 years ago
Yep, normal.
arbitrarium-box 5 years ago
My ML was being dodgy but not in the usual 'shutter won't open' manner. On mine the shutter opened on the second wind-on, and stayed open until the shutter release was pressed. I assumed it was something to do with the magnets but after trying a few things I unscrewed the two screws you mentioned, slid the assembly up and re-tightened the screws. Works perfectly now. Kinda feel like I scammed the camera shop now as I bought it half price due to the shutter malfunction =P

Hi there great post! I have seemed to have got somewhere closer than I had before which the shutter was not opening at all. Anyway now the last problem (or so I think) is that the shutter is only firing one time and I have to then manually fix the mechanism and then again... but if anyone is out there aha that can possibly help that would be fantastic! Thanks

Hi,

I have a PL with an unusual issue. Ive opened up as per instruction, and the catch hooks on ok on first wind, then everything looks ok on second wind, but when i press the button, you hear a click but nothing else moves. You can wiggle the latch and the pin goes back to normal position. At this point the shutter is wide open, and i can wiggle it to see it move. but as i cock the shutter again, it closes, and the same process repeats. One thing of note, when i open the lens, the self timer flickers and the low light stays on (as indicated on the manual when the camera is taking a poor light picture which lets you know its still open) So, it looks like its half way through a picture cycle, but i cant seem to figure out how to get it to complete this. Any help would be great. The low light is constantly on, and when testing the battery, the green light comes on.
Nymphadora_ 3 years ago
If you have a situation where the shutter won't go off, you turn the camera around, check it out, try again and it works, look at your fingers under the flap in front. If the flap/cover is lifted a tiny fraction, the shutter will not operate. This happened to me and finally I caught what I was doing. It was very slight but the cover was not all the way down. Nyms

Hi, Thanks for that, sorry for slow reply..was at a gig watching L.A. Witch, so just recovering!

I did as you suggested but to no avail. Its really weird, it's exactly as it says in the manual when its taking a long exposure. Same lights and response, but just wont complete the cycle. I am sure once this completes, the camera will be in full working order. I've repaired around 15 cameras from my collection, and this ones driving me crazy! But thanks for the response, much appreciated. Ger

Ok, i tried something a bit different but along the lines of what Nyms mentioned. I opened the front flap but tried to get it at the point where the self timer light flicks on but just moving a hairs width at a time..it fired. I have wound it on and tried again..only 1 click. Did the same..fired off for second time. Too dim to be messing about again, but will try again tomorrow. Thanks Nyms. Definitely put me on the right track. Cheers. Ger

After performing the repair to my 35GT (some years ago, which I got for free as shutter not working ) the first roll of film all the shots taken on a bright day were underexposed. Anyway since that first film I leave the backlight switch in the 2x position and the camera exposure as never let me down under any lighting conditions. Why this works I have no idea. It may be just my individual camera. Give it a try its a fantastic lens on this camera. I've posted over 100 shots in this group many under difficult lighting conditions without issues.

Nymphadora_ Posted 2 years ago. Edited by Nymphadora_ (member) 2 years ago
Ohh...!! If you don't have the actual Minox black plastic plate that goes into the hot shoe installed, then the camera is programed for flash only. If it's not there, hold the camera in shooting position and look into the hot shoe...in the upper left corner, inside the hot shoe, is a tiny black switch. This activates the circuit inside the camera for flash. ONLY for flash. The original plate that goes in there has a tiny notch that locks into the tiny switch and keeps the black plate from falling out. The plate stays in ALL the time unless you slide a hot shoe mounted flash unit into the hot shoe. If you keep the flash on the camera, but turn the flash off, the exposures will be off because the camera is 'looking' for the little notch.
If you don't have one you'll need to make one out of two thicknesses of an old credit card. Card board is too soft. Make the square the same size as the hot shoe. It is 18mm wide left to right, 16mm front to back. The notch is 3mm down from the front left corner, 1mm deep from the left edge. Once the notch is in, make a 3mm taper from the deep part of the notch, tapering over to the left edge. This is needed because the switch is at an angle and the taper is the same angle as the switch...it will rest in this angle. Lastly, on the upper left corner, just above the notch, file a tiny 45 degree angle so the plastic plate can push past the switch without hanging up. The depth of this 45 degree angle is only about 1mm down the left side and 1mm towards the right side.
When shooting normally, without flash, this plate ALWAYS stays mounted to the hot shoe, like a protector. If you have any type of hot shoe plastic protector for another camera, then you simply file the notch and taper.
Here is a link to the image. Hugs...Nyms

Nymphadora_:

Good point the flash sync speed on the GT is 1/125th so depending on available light could under expose but goodharbor shots looked to be in good light. So may not be the problem. Note on my GT I set the asa dial to box speed and the backlight to 2x. to achieve correct exposure. It may be some kind of calibration issue after shutter repair or aging electronics?

Hmmm.....you might try a flash unit on the camera if you don't have the hot shoe plate and see if those images are exposed correctly... Nyms

I also love this thread. I recently restored both of my MLs using the instructions here. Thinking about it I have to do this every year or so. I wonder of the problem is that the two screws become loose and move, such that some liquid thread lock may help improve the situation.

Has anyone tried such a thing ?
Nymphadora_ 2 years ago
You could try that but it may be a little permanent for such tiny screws.... often, a few drops of clear nail polish across one edge of the screw, keeping it out of the Philips slot. If you need to work on it again just push the dry polish with a screw driver and it will chip right off. Nyms

Hello everyone, I got a Minox 35 GL but as you can guess I'm having problems with the shutter.
I already opened the shutter mechanism and slightly bent the foils, the camera seems to work fine when shooting "long" exposures but if I try to shoot against bright light or on subjects which require shorter shutter speed it won't open.

I tried many times with different openings, light conditions and using the 2x. The issue is still there. It seems that when the shutter blades are not opening they are just rotating a bit.

I'm starting to think that the problem might be related to the circuitry. Has anyone had an issue like this?

thanks!

Just to be sure, what type of batteries are you using? I found a post recommending 4 LR44.
I wrapped them with duct tape, only the tips are exposed.
I talked to a local service store and they told me that the springs also have to conduct power. I will try to clean all the parts and contacts.

Some duct tape conducts electricity, which would effectively make your 4 batteries into one. Or none, I'm not sure which. Anyway, it's easy to check using your camera's battery test switch.

Thanks!

In my experience on a couple of MLs it is a fix that works for a period of time, at which point you follow the instructions again that fixes it again for a period of time, at which point you ... lather, rinse, repeat. So, a temporary fix that appears to be repeatable.

You really do have to keep an eye and an ear on the shutter to make sure that it is opening when you think it is. I check the shutter before and after every roll of film. So far I have managed to keep the number of lost frames down to a minimum. (touch wood).
