- A jammed shutter curtain on a Minolta X-370 or a X-600 that is crinkled and wrinkled. For example the shutter curtain on a Minolta XG1 or XG7 can also have the same malfunction, all caused by the shutter curtain connecting bands slipping off of their guide rollers. This video attempts to show how to access and repair the shutter band roller issue causing the jammed and wrinkled shutter on a Minolta X-series camera.

Thanks for the quality content. This is the exact issue I've been trying to fix for months. I thought I had bricked my X-700 beyond my ability to repair.
That is a pretty serious teardown. Wonderfully done as always!
Indeed it is a little more complicated than some. Thank you for your comments and interest in FOC.
I recognize that X-600! I didn't realize just how hard this repair was. Thank you.
Indeed. And that was just the half of it. You surely have a good eye for your cameras. Several cameras you have submitted for repair through www.phototronic.biz/ have ended up featured in a FOC videos and you have spied them all.
And I always love seeing them up here, too! I sent this link to the guy in Japan who sold m the 600. He knew of your channel and was impressed.
This community of classic camera enthusiasts is very gratifying.
This was extremely informative! Thank you. I was able to snag an otherwise wonderful condition X-700 from a thrift store for $20, and it worked great through half of a roll before the curtain started having issues. With your video, I have the confidence to put that $20 on the line, and DIY it.
Did it work out
Es usted un genio! Gracias por inspirarnos!
WOW. Another fantastic video.
Thank you comments and for your continuing interest in FOC.
On a couple of your videos you describe adjusting the position of the blue gear in relation to the idler gear. I know there's a timing mark on the blue gear but what I don't understand is what you're lining it up with. Is there a similar mark on the idler gear to match it up with?
There is not, you have to experiment with the position of the second gear to determine the proper position. After you to it a few times it will become instinctual.
Great stuff. My Canon Motor Drive MA is hesitant and goes off erratically. I wonder if you could do a video on servicing/lubricating the Canon MA motor unit? Thanks.
(I checked and cleaned the contacts and the battery chamber, all fine, it's def. the unit)
Indeed that would be a good piece of accessory equipment to feature in a FOC video. If it is hesitant to wind, but still cycles lubrication of the the various gear post hubs might help. Also check the MD timing contacts of the camera body you are using it on for positive connectivity.
Does this problem happens in the Pentax k1000 cameras too? I got a couple that have the same looking curtain
Awesome channel, bought an sr-1 which had a shutter in similar condition to the one in the video but has a broken strap and slit so it needs to be replaced. Do you think you could do a video on how to sew and re-glue a new shutter fabric?
Thank you for your interest in FOC and for the suggestion.
Amazing video, as always. I picked up an X-370 with what I thought was the same issuse, but it turns out the curtain on the left has come unglued from the roller. What can I use to re-glue the curtain? Thanks.
Pliobond. It is forgiving while it is curing to allow for secondary repositioning if needed. Once it is completely cured it is strong and long lasting. It can be cleaned up from most surfaces with alcohol and for the most part is safe on plastics.

Fix Old Cameras Thank you very much for the help. The camera is now cycling properly. You’ve saved another one!
This sounds like narration in the old Blade Runner. I love it
It is all good, a little droning, a little of stating of the obvious, and maybe just a hint of some relevant information. Too much fun. Thanks for taking time to comment and for your interest in FOC.
Hey dude really great vids! I just bought an old X500 and everything seems to work fine but when i fire the curtains just go half the way it should... it seems that te curtain he's not derailed or anything, any idea what it could be ? thx very much in advance
There are plans for an upcoming FOC video addressing the possiblility of a misplaced wind idler gear in a Minolta X series camera causing such an issue. The gear lives on an adjustable base on the wind side of the bottom of the camera.
Hi what would you recommend to glue new leatherette to a camera? Im replacing all the leatherette on my Contax with a vinyl with cloth back. I used pliobond as recommended by many but the smell was just putrid beyond what I can tolerate. Any recommendations?
Yes, the warning label on the container advises to avoid prolong exposure and to use in a well ventilated area. This camera repairman has been using it for so long that it has become an accepted part of the process. However, it is strong and it is understandable that some would want to avoid it. The are several brands of permanent glue sticks that work quite well for attaching most flexible leatherette and yet still allowing for future removal should it be necessary. If the leatherette is to stiff for successful use of the glue stick, double sided transfer tape can be used.

I'm working on my X570 with the same issue. I'm at the point of the separation of the shutter housing and wanted to know how "the shutter can be manually tripped" for testing. Thanks!
The shutter cam gears are typically gray plastic and the shutter wind gear is typically blue plastic... nestled between the shutter cam gears stack and the shutter wind gears will be the shutter latch lever (typically brass colored) flick the lever and the wound curtains will release. You can then wind the curtains again by placing your thumb on the wind gear and rotating away from the shutter proper.
Hello. I'm having problem with repairing minolta x-700 with no movement of diaphragm-control lever when i fire shutter.
I managed to remove the lens holder to look around the lever but couldn't get any good results.
Everything seems to work fine but the aperture-control lever, which results in no control of lens aperture.
Do you know how to fix it? Thank you!
If the aperture lever does not move in all modes (causing the lens aperture to stay open upon release) the most likely cause is the aperture control magnet has failed or is sticking because of an oil film or is being held because of a mechanical linkage malfunction. Not as likely, but still possible, the camera could also have an electronic control failure, which would also be the cause if the issue is isolated to the P mode.
Do you know how to disassemble x-370 shutter gear and oil them? and how to correct shutter speed on x-370 and x-700. Thank you.
Maybe at some point in the future such a FOC video could be made. If you are inquiring as to the possibility of getting it repaired go here. phototronic.biz/
Otherwise, thank you for your comment and for your interest in Fix Old Cameras.
Also how do you remove the advance lever on an x370, i have been able to remove the asa dial but haven't been able to find the retainer for the advance lever
Peel up the rounded off triangle shaped leatherette cover over the advance lever position. Under it you will find two screws. Once the screws are removed the remaining plate can be lifted free to reveal the advance lever retainer.
Hi i have an xg1 and it wont turn on and i cant advance the film advance lever. I have tried to change the batteries and tried different positions for them. The battery compartment also seems fine.
A nearly invisible film of corrosion on the battery lid often blocks the current flow. Make sure the battery lid contact is polished clean. Another easy although often temporary fix demonstrated here.

Please one of a Minolta x700, I did this procedure but it's different for this camera to remove the front plate assembly
Thank you for your interest in FOC and for the video suggestion.
I have a problem with my xg9 advance lever, it is loose and won’t advance the film. I used L44 batteries for a week and then this problem showed up, so I decided to change to SR44 but still won’t work. Lights turn on ( outside and inside).
Check the shutter position. th-cam.com/video/XwKnW1dMEtA/w-d-xo.html
i have a problem on my Minolta xg-s (xg-9), the curtain moves to the right when I advancing the lever as it can fire. but the curtain wont open at highest speed. when at Bulb, the curtain only open halfway when I fire the shutter, but then the curtain will not fully close after that. I have to push the curtain to the left manually with my fingers to close it and in order to advance the next frame. Can you please help me. Thank you.
Probably needs the shutter curtain tension increased or the shutter curtain band (the ribbon rerouted on to pulley in this video) glue has dried out and has allowed the tension to slip. If that is the case any tension adjustments that you do will not hold and the shutter curtain unit will have to be repaired.
What can you tell me about a minolta x7a camera, that when it is on high shutter speed, it fails to do so, photos come out under exposed? I was told it was a shutter issue?
If the exposures are even yet underexposed, then it could be a meter issue as well as a shutter issue. Check camera / lens settings and aperture linkage as well if you have not already done so. Is the ASA set correctly? A simple fix, but easy enough to over look.
I have a problem with slow speeds on my XG-M, the shutter curtain is a bit sticky, it doesn't move all the way to the left, it needs maybe a couple of mm, but it seems ''closed''. Also, when advancing to the next frame it is a litle tough in the beginning, and after a few degrees it continues as it should. The faster speeds work properly. If the light seals have perhaps deteriorated and lodged in the tracks, is it possible to clean them?
Increase the curtain tension a small increment and check the main wind gear in the bottom of the camera for depth of engagement and proper tooth alignment. There is an adjustment screw, when loosened, that allows for this adjustment. If you are unsure as to how to proceed, and are very patient an FOC video will eventually be produced covering this issue.
Thank you for your reply! I did an adjustment of those gears on an X-700 if l remember correctly, but I'm not sure how to increase the tension on the curtains. I had to do that on a Zenit, but it was pretty obvious, since there are 'cogs' under the bottom plate, and when turned add more tension or slack on the curtains.
The shutter tension adjustments are underneath the battery chamber. You will need to move the plate that contains the battery chamber to gain access to the adjustments. You can leave the battery contacts attached if you are careful, just fold the plate over out of the way. There are some FOC videos on adjusting the curtain tension of various cameras you might watch. Also this video gives a detail view of the style of shutter assembly you will be working with. th-cam.com/video/HhtlqzLlRBA/w-d-xo.html
I have a minolta x 370 but i can't get the two screws on the bottom plate near the rewind and advance side taken off, What should i do?
Heat applied to the head of the stubborn screw from the tip of a soldering iron should help. BE AWARE... the bottom plate of a X370 could be foil covered plastic. Do not allow the tip of the hot iron to come in direct contact with the bottom plate of the camera.
Is my Minolta Xg-a broken if the advance lever does not move the two dowels inside the film chamber
The camera will not wind, if the shutter has not been released. The shutter will not release if the battery is not good. If the battery is good and the shutter still does not release then check for a nearly invisible film of corrosion on the battery cap. Even the slightest hint of corrosion will block the current flow from the battery.
I have older Minolta Maxxum 9, I seen viewfinder still dirty, I tried cleaning up but it still dirty inside, how to fixing inside viewfinder before cleaning up?
The viewfinder screen can be removed via a clip at the center front of the screen. Handle the screen carefully as it will scratch easily.
My Minolta xe-5 only works in bulb mode. Otherwise the shutter doesn't open and the mirror does not fall back. In bulb it does work. I don't know what's wrong. Anyone had a clue?
I'm having some problems with my Minolta x-700, as the shutter sometimes doesn't fire. the leds turn on like they should, and when i press the shutter button the camera loses power. if i pull out the advance lever about 30 degrees it fires. could it be the infamous capacitor?
If the display turns off when the shutter button is pressed and will not come on again until after the on/off switch is set, the problem is probably the Timing Switch is not closing. Peel back the leatherette below the self -timer switch to gain access to this switch.
Thank you for your reply! Can you tell me what would my course of action be after that, do I clean it or perhaps change it?
Have two problems cameras, can you assists or suggests?
ATG Rolleiflex 3003r
Minolta 9000
Both have fresh batteries,. Shutter locked up, mirror locked up & shutter cocked.
What are the problems before sending it in to ATG?
Both are electronic release. Simple, but important. If no power, check battery contacts for invisible film of corrosion and polish all contacts. If power, but no release, check for proper voltage from batteries. Otherwise, mechanically trip the shutter... if not, jammed mechanical function; if release, electronic circuit or switch contact issue.
@@FixOldCameras I stated those batteries are fresh. Means & tested with DVM.
Were those educated guesses or saying something that you have never worked on?
@@angelisone You make me smile... for decades the narrative goes like this. Customers insist the batteries are "fresh". On a digital volt meter that might even check out close to or right on the required voltage. However, a digital volt meter does not give a read out of voltage under the load demand of the camera release cycle. It does not give the available current under load on a voltage reading. The release cycle of most classic electronic release cameras is usually the highest current demand of all of the camera's functions. In addition classic cameras are prone to developing a nearly invisible non conductive film on the contacts. If assumptions are made to the validity of the availability of proper current flow level from the battery through the contacts, without solid confirmation, than a simple fix is overlooked and unneeded disassembly and troubleshooting is pursued. To state the obvious again... it is worth double checking and not assuming the battery and battery contacts are not problematic. Finally, electronic cameras that are still locked up with confirmed release power availability can have an electronic failure, a mechanical failure or an electro-mechanical failure. All which would apply to your brief description. Thank you for your interest in Fix Old Cameras.
@@FixOldCameras I understand what you have said. But I have five 9000 and four 3003 camera bodies.
Those batteries switched to other cameras work fine.
Just like some of my Vivitar 285HV, three fire at full power, in any setting.
I find not right solutions on two, camera & flash. Many people having these problems.
But no one reply with the actual problem or fix.
Tengo una Minolta xg2 la cual no dispara y no corre la película. Cual seria la solución?
comprobar estado de la batería... limpiar los contactos de la batería
The Minolta XG-2 as a battery dependent release and the slightest film of corrosion on the contacts will prevent operation. The film of corrosion is often not visible at casual glance and the battery cap is usually the culprit. Polish and clean the inside of the battery cap.
Do leica r3 pls!!!
xg9 esta trabada la carga, como lo soluciono? muchas gracias
bateria...?
Check for a light nearly invisible layer of corrosion on the battery lid/cover. The Minolta X-9 is battery depended for release and even the smallest film of corrosion can block the current flow from the battery thus effectively locking up the camera advance. Also sometimes the curtain will hang up as shown here...

This video made me anxious
Me too. Just kidding. Not as bad as it looks. Patience and persistence.
@@FixOldCameras true. I'm still gathering up the courage to open my Minolta X-7. There seems to be smudge in the viewfinder prism and I want to clean it off but I can't find any tutorials on how to do it specifically for the X-7 not X-700. Sounds like I have a not so popular Minolta model.
@@Thato It could be the smudge is on the outside of the screen and was caused by degrading mirror cushion foam. If that is the case use a lint free cleaning swab dipped in distilled water and following the concentric rings of the screen see if you can clean away the majority of the smudge. Do not use lens cleaner on the VF screen as it will likely stain of fog the plastic lens of the screen.
@@FixOldCameras Awesome thank you for the suggestion! I will definitely give that a try :)
it was scary to open up to the curtains, but when there were 5 of them, there was no way out, all 5 were repaired
nice
Thank you.
How much would this cost if I took it to a camera repair? I think I botched my attempt
If you are interested in possible service...

What do you do when the shutter button doesn’t work??
With the XG series of cameras an invisible film of corrosion on the battery lid can block the flow of current needed to release the shutter. Also check out this video for a possible solution...
