There's a lot of discussion on this forum and others about the succes rate of the solenoid replacement method to fix the aperture block failure of K-30/K-50 and some other models. So far, most evidence are more or less on a case by case basis and it's difficult to establish for sure how well this method works.
So, I thought launching a poll about this could help to have a clearer picture about this repair. The choices are:
1) Solenoid filing, camera works OK. The green solenoid was put out, filed, and put back in the camera.
2) Solenoid filing, camera worked for some time. Meaning that the camera worked fine after the repair but ABF reappeared or still happened intermittently.
3) Solenoid filing, failure. As 1), but the filing didn't solved the problem.
4) Solenoid replacement, camera works OK. The green solenoid was replaced by a another one. It didn't matter if the replacement solenoid was new or salvaged from another device.
5) Solenoid replacement, camera worked for some time. Idem as 2), but for the soleind replacement as described in 4)
6) Solenoid replacement, failure. Same as 4), but didn't fix the problem.
7) I broke the camera during the repair. This question is to evaluate how risky it is to attempt the solenoid reapair procedure.
8) California repair, camera OK. Although we don't know exactly what the guy does, AFAWK, it's similar to one of the two procedure above and can be a more convenient option for many, if not most, people.
9) California repair, failure. Either the California repair didn't worked or the camera worked but started to show ABF after some time.
So, if you tried a solenoid repair on a camera with aperture block failure, please answer this poll. This would help a lot to better know if and how well this procedure really works.
Thanks in advance to all of those who will answer!
