Re: my fix of the K-30 aperture problem without disassembly

Had the same problem with my K30. Tried this method and it worked. But the problem returned so I did it again. Worked again. But after a while same again, dark pics.

After repeating it a few times I could not losen it anymore. I then gave my K30 for repair but it wasn't the solenoid alone which was damaged but the complete diaphragm block!

Repair would have been to expensive, luckily I got my K30 back and tried to replace the solenoid with a white one I got from a defunct K20D. No luck. I ordered the diaphragm block. I unsoldered the green solenoid which was to be found there and installed the white solenoid of the K20D and then built this modified diaphragm block back inside my K30.
Now it works fine. I could have saved a lot of work (and money) if I would have changed the solenoid first.
