Good evening all. I have a Yashica Lynx 1000 that I bought from a bootsale for a whole £5. I sorted out an issue with the film not winding on but the shutter sticks at anything below 250s. What can I do to free it off or should I just keep working the shutter and see if it works?

The usual amateur manner of freeing stuck or sticky shutters is cleaning gently in naptha, often found in the form of 'Ronsonol' liquid lighter fluid in the USA.

Use in a well-ventilated area, use at your own risk, etc. If you Google, you should find plenty of information on the method of cleaning and freeing stuck shutters.

If the camera is one you wish to have professionally repaired, there are some places yet that will do the work for you, probably with a better chance of a positive result.

The Lynx 1000 is an interesting camera, as it is a typical fixed-lens rangefinder but with a maximum leaf shutter speed of 1/1000 (hence the name). Nice little camera, as are all the Yashica Lynx models. Best of luck with it!
 
How would I dismantle it? There seems to be a retaining ring I can unscrew but beyond that I am unsure.

I have not got a 1000, but my Lynx 14 is accessed via the trim ring on front, then the front lens element can be removed. You will need a lens spanner to remove properly.
 
I had a similar problem with a Lynx 500. I did clean the shutter blades with Ronsonol and appeared to be working well but when i got the test film back, the pics takes at 1/30 and 1/60 were over exposed. So i ended up selling that camera.
 
I used a similar cleaning method a couple of times. If the slow speeds are sticking though then the escapement is gummed up.
 
I have taken the front lens element off (really easy by the way) but it hasn't helped. 1000/250/1s and bulb are fine but anything else sticks. May dismatle is but got loads of cameras that need my attention.

Taking the front element off does nothing by itself. Did you clean with Ronsonol or another naptha-type cleaner and q-tips?
 
Yes,gave the blades a good wipe down. If I rotate the speed select ring then it will release if stuck.

Gotcha. Sorry it didn't fix your problem. I have a reasonably good percentage that do respond. Some work after I hit them with the Ronsonol, but sooner or later need it again. Nothing beats a good CLA by a great repair person.
 
What it sounds like is that the slow speed timer mechanism is sticking. To rectify this, you have to flood the mechanism with the lighter fluid and cycle the shutter repeatedly. It may take a few applications. If you have compressed air you can blow out the excess fluid after everything is working, but then let the camera sit after that for a few days lens up so it dries out thoroughly. Sometimes after this waiting period the shutter will still be not quite right, and will need another round of fluid, sometimes not. After you are satisfied with the results, set to B and run aperture wide open and clean the exposed lens surface to remove lighter fluid residue. I use Q Tips and a 50/50 mix of peroxide and ammonia. This will also remove any fungus that may be present.

I have been using this method for many years with excellent results. Good luck with yours!
