Any ideas on how to fix sticky/stuck aperture blade on Yashica T3?


Recommended Posts

I recently purchased this Yashica T3 camera in almost mint condition for more or less current market value. The previous and only owner said they literally only used it once. I popped in a roll, began to shoot, but after about 5 frames with perfect operation, I noticed that the after the 6th shot, one of the camera aperture blades seems to have gotten stuck.

 

I tried to shake the camera while pressing the shutter in order to see if I could get the blade to be released but it has not worked. Does anyone have any ideas on how to fix this without a crazy complex disassembly (the shutter assembly seems very difficult to get to - A repair manual can be downloaded here: MEGA)?1381928319_MicrosoftTeams-image(18).thumb.jpg.175d0c8f4cf7e99a5ce785d284e230f6.jpg 136827830_MicrosoftTeams-image(17).thumb.jpg.faa4f690300324337b36e52753b7f181.jpg

Alas, blades are synced together by virtue of pins running in holes and slots. Once something is amiss like that, crazy disassembly is usually the only way to fix it. Worse, it's likely to happen if a blade has a damaged pivot and parts are rarely available.

Sometimes "mint" condition cameras can have more problems than ones that are well used, since parts that haven't moved much in years can seize up. It could be an electronic issue, as well. Things like sticky shutter magnets and capacitor problems are not uncommon in older electronic cameras (this model dates from the 1980s), which is why I would never pay too much for one.

Also, if it's something like a shutter capacitor that may not have charged up in over 30 years, the camera could come back to life after a while. You might keep a battery in it for a few days and try using it periodically. It's worth a try, at least.

If it can't be returned, I'd chalk it up to bad luck. They're poor candidates for DIY surgery and few techs can or will tackle a repair. Classic fixed focal length Yashica and Oly p&s cameras were always fragile relative to SLRs. Despite their cult status, they can be heartbreakers given their cost and poor prospects for reliable repair if they crap out.

Just don't buy another one.

I need this repair manual but the link provided is no longer working. could you do me a favor and send me the file to email zhang.meng@163.com ?

I can attach photos here later one once I fixed my T3.

Many thanks!

At €369 - how can it possibly be bad?

I don't believe they cost that much when brand new, and 15 years ago you couldn't even have given them away! 

Strange times we live in, and stranger values. 

FWIW, I just saw the prices being asked online for an old Tektronix digital storage oscilloscope I bought used 10 years ago for £75. Anywhere between £300 and £600 today... when you can buy something brand new and with a higher spec for under £200.
