K110D shutter failure

I'm sorry to report that my K110D no longer functions:

- shutter won't release - manual, bulb, auto
- no autofocus activity
- no focus indication

although

- camera powers on
- display seems to work OK
- flash pops up in low light
- mirror lock-up for sensor cleaning works
- without lens attached, shutter fires

JFTHOI, I've tried:

- cleaning battery terminals
- different (charged) batteries
- making sure lens is in A position
- manual focus mode
- different lens
- different SD card
- resetting menus to original factory settings

I should note that I recently bought (from a pawn shop on fleaBay) what was supposed to be a Pentax mount (Tamron) lens, but only after trying unsuccessfully to mount it, I discovered it was actually a Nikon mount. (:-( I wonder if trying to mount the wrong lens might have shorted something out in the camera electronics. (:-(

Local camera store (Mike's in Boulder) repair department says they can only fix very basic DSLR issues but electronics-related problems have to go to Pentax Service (in nearby Westminster; alas, no walk-in drop-off (:-( ).

Anyway, before I send this off to Pentax for an estimate, I'd be most grateful for any suggestions of other things to try to get this camera working. Wondering if there's some sort of hard reset (as, for example, in Palm PDAs, or power management reset, as in Macs). Any point in trying to reinstall firmware?

What happens if you manually focus a lens? Will the camera show focus confirmation in the viewfinder? (green light?). If you get a focus confirmation, does the shutter then fire in either MF or AF settings?

Consider cleaning the contacts on the lens mount of the camera body. Use lens cleaning fluid or methyl alcohol on a lint free cloth and gently rub them.

To try a camera reset if the above does not work, take the batteries out overnight.

If it still won't go, use a loupe and examine the contacts on the lens mount to see if one of them has been pushed into a wrong position.

Try to set allow aperture ring in menu and try it, I think it sounds like the contacts too.

No green hexagon, no red LED focus indicators

Tried cleaning contacts.
Did camera reset.
Took batteries out overnight.
Don't have a loupe to check contacts; anyway, with unaided eye, contacts look like OK K10D.

Seems like it's time to send this in for an estimate by the pros.

Belated thanks for your prompt and helpful responses; alas, I've had to focus on some more important things in my life for a bit.

Doug, have you tried firing the shutter with a remote? If you don't have one, maybe the guy at the local camera shop can let you try one out.

If it works, then at least you know the shutter mechanism is ok and the problem is likely to be the button.

Good luck.

How many actuations has the shutter performed?

No, I didn't think of *that*.

I've got some 5300 images from that camera in iPhoto, so I'll guess maybe 7000.

Anyway, Pentax Service says $231 to replace the $100 circuit board and overhaul the camera; the repair comes with a 12-month warranty. I wonder if that money might be better spent on a new(er) camera.

Also wondering how one of those extended warranties (e.g. Mack) might cover me in this case, and who'd be doing the work.

another idea. when in menus, or review pictures, does pressing the shutter release put the camera back into the shutter ready mode? i think it sounds like your shutter button might be wonky
