d300 aperature lever sticking shut
Aug 28, 2013

On my d300, about 2 months ago, the aperature lever started sticking. I've researched the issue and have found several threads on the topic, but they are different problems, mostly related to a bad connection with the lens.

I have posted a video of the problem, which is more useful than I could type out, and that is here:


And continued:

Does anyone know /why/ this is happening?

Is there a diagram of the internal parts somewhere? I'm an electrical engineer and am not afraid to take this thing apart--although, the only videos I've seen of the disassemble are destructive.
