Pentax K5II Lock Up

Hi all,

My K5II is approximately 9 months old and still under warranty having been purchased through SRS but I am trying to find out if mine is an isolated issue.

About ten days ago when using my camera in manual mode with an A50 lens, the camera suddenly locked up, with the red focus square permanently illuminated in the view finder and no response from the shutter release button. I tried switching the camera off and on but it made no difference and I noticed that the top LCD plate was illuminated and showing details of the exposure even when the camera was switched off.

I removed the battery (OEM) and replaced it which seemed to cure the fault.

Since then, and while using a variety of lenses, latterly my DA 35mm Ltd, the fault keeps returning and the only way I can get normal function again is by removing and reinserting the battery.

I was looking for any advice and to see if anyone else has experienced a similar problem before I return the camera for repair under warranty.

Very many thanks.

I have never experienced the problem you are experiencing with my K5ii..

My K-5 II locked up in the first week of use when I got at the end of last year. I installed the firmware update and it has not locked up since then.

Cheers.

Thank you all for your responses.

David, I am a bit OCD about cleanliness so I think I can pretty much discount electrical connections but I will try a factory reset and firmware update but I might have to wait until I have a more reliable internet connection.

I have done some searching on our sister forum and apparently by his exact fault has been replicated over there and resulted in a replacement camera being issued under warranty

I am hoping but he suggestions on here work for me as the last thing I want to do is send off my little precious for repair.

Okay, contacts cleaned again for good measure, factory reset and latest software update carried out so now on V1.07.

I will of course let you know if my intermittent fault returns - hopefully sorted now, but i have no way of telling until I have taken a reasonable number of actuation's.

Thanks again to all.

Hi Don

If the problem does re-occur I wouldn't discount the battery as the cause. If it is not giving out the correct voltage it could easily be causing problems. Also, don't read too much into similar issues reported on other Forums, a 'lock-up' is not a definitive problem and could be because of umpteen different things.

Regards
David

David,

It appears the factory reset and latest firmware upgrade has done the trick as have not had any issues since I last posted on this topic.

Thank you all for your help.

My IIs did it 3 times in the 1st couple of weeks, I said Id send it back if it did it again, it never did.
My advice is to just use it, let it settle down so to speak.
