I was out shooting with my Techno today and the rise and fall on the back seized up. The knob is extremely hard to turn – I’m located to try force it, but it does move if you put force into it. I can’t see anything that might obstruct movement when looking at the thread that is exposed when looking at the inside of the standard and was shooting indoors, so nothing extreme. I’m guessing these things are pretty simple in terms of build, being mechanical parts only, but I’m guessing they’re really fussy in terms of tolerances. Does anyone out there know if there is anything I could do on my end to try fix it, or do you think I’ll need to send it off for specialist care? I have a friend who is a trained Hasselblad and Olympus repair person who I could ask to look at it, but I don’t want to do that if it’s possible to put something out of absolute alignment in the process. Anyway, your advise is appreciated as I’m stuck without the use of it.
