Pentax K2000 No Manual Control

I'm experiencing a weird problem lately with my camera and auto lenses. If I set the camera to Aperture or Manual on the dial, often I can't change the f-stop and/or shutter speed. I'm about to reset to factory settings to see if that helps. Has anyone else had this issue?

I'm running firmware V 1.11.

Do you have a battery grip fitted?

If so, check that the front and rear dials on the grip aren't sitting between the detents.
This can cause the ones on the body to be unresponsive.

K2000 takes no add-on grip, mine doesn't at least.

As Alan said, no grip. I tried restoring the basic and custom values back to factory and removing the batteries - no go. Manual and Aperture priority do work for my FA 50 1.7mm. But not for my DA 18-55mm and 55-300mm.

The camera is less than a year old. I hope it's not broken. I have taken good care of it.

If it works with some lenses but not others, it sounds (to me, at least) like the problem could be in the lenses or, more likely, the contacts between the lens & mount. I don't know exactly what all of the pins do, but maybe one of them determines if the lens in use is a "D" (digital) lens and tells the camera how to behave.

If it were me, I'd first check that all of the pins on the mount are clean of debris and move freely. Even if they look clean, run over all of them with a Q-tip dipped in isopropyl alcohol (you can get 91% at most Walgreens or CVS stores - that's what I've always used for cleaning these types of contacts).

Failing that, I'd try to find a shop that carried Pentax DSLRs, take it in and very kindly ask if I could try a few of their lenses (other D and non-D lenses) on my K2000 and also try my lenses on one of their camera bodies to try and establish some logical pattern of behavior.

Thanks for the responses. What I have found is that I can control the shutter but not the aperture for D lenses. I'll try cleaning the contacts.

The camera was broken and serviced under warranty.
