Originally posted by photolady95 I am now convinced, based on the feedback from the OP in message #4, that we have been confusing two different problems, sometimes in the same thread.
(1) The aperture control problem, which is where the thread you referenced started, causes severely under-exposed images to be created, because the aperture is not adjusted; the easy "solution" for that is to use m42-mount lenses because their aperture control is totally manual and totally separate from the camera.
(2) Shutter operation, which is where the thread you referenced wandered to, causes totally black image to be created, because the shutter is stuck shut; this obviously is the OP's problem, and I don't see any solution other than sending it in for repair {or buying a new camera}
As for the "lots died" ... we have no statistics; we don't know how many shots the average K-30 is good for. I can say with certainty, that more life is one of the reasons for buying a K-3 instead of a K-n0.
