K10 grip pin down

Has anyone had this problem? It is a genuine Pentax grip for the K10
Has anyone taken this apart to find the problem?This pin controls the autofocus, unfortunately
the only thread on this forum is over a year old and has not been solved

BTW I already tried electric spray


thanks

I had the same problem, only mine was a corner pin. I used a hobby knife to cut enough plastic away to let it move and it has worked ever since.

Hi Parallax,

Can you offer a little more detail of your process. I had the same issue and tried your hobby knife technique and I'm not having success with it. I carved out some plastic around the pin. When it didn't pop back by itself, I figured that since it was spring loaded (at least the other ones were) I could press down on the pin to help it spring back. I ended up just pressing it farther into the hole.

Was your pin still spring loaded when you worked on it? How much plastic did you carve out?

Thanks!

Try to poke the pin with the point of the knife and lift it up. They are soft brass. Once it's up, straighten it if necessary.

I didn't try to raise the pin but I reseated the grip and it seems to be functioning fine right now... as far as raising the pin, isn't it on a spring?

thanks for the great help so far

cheers

Yes a member here had the same problem. He keeps the pics/post active so others may follow the directions to repair your grip. Its a fairly (relative?) simply job, no soldering...

My shutter button main switch that enables DOF preview, or live-view was failing big time. The shutter button main switch would stick on over on live-view, DOF... ;not good at all. My grip has no warranty now. I Had nothing to lose so I used the pics below and the dSLR service manuals to fix my problem. I had to clean the contacts, then the step some forget about is I used a suitable very thin layer of lubricant as called for in the service manuals for Pentax dSLRs. Grease is used on the edials just a note. Here is all you need to know to take it apart.

Thanks for the tips Parallax. It's all appreciated.

I think my pin is down the hole too far to tease out with a knife. I tried without success. My spring must have sprung on that pin so it doesn't want to come back up. It's a bummer that my grip isn't 100% functional, but the good news is that I lost functionality to something I probably won't use too often. The battery functionality still works fine as well as most of the controls, but one of the control dials is non-functional because of the pin.

Thanks again.

I also had the same problem with one of my pins. I tried everything to and get that little bugger to pop back up but it just wouldn't budge. I finally got it unstuck with a flat head micro screw driver. I jammed it in beside the pin and pried on it until POP, it was back up. I now am a little more careful when I have put my grip back on after changing the battery.
