K-50 Screen and Button Issues

Hi all, I'm currently travelling the tropics taking photos of my favourite subjects - frogs.

Last night I was out with my K-50 in some heavy rain taking photos as usual. When I got back (to review my photos) I realised that my LCD screen was not turning on and that none of the buttons at the back were working. The screen is however working when the camera is switched to the video mode. Another thing I've noticed is that the lenses are automatically focusing without me pushing the shutter button.

Has anyone had a similar problem to this before? If so how would I go about fixing the camera - hopefully without voiding my warranty.

Welcome to the Pentax Forums!

The most likely cause of your problem is moisture intrusion. The camera's seals will resist both water and dust, but given enough time in heavy rain and/or a poorly-closed flap and water may make its way into the camera. The conventional emergency treatment is:
  • Remove batteries from camera (important)
  • Remove lens to allow air circulation
  • Open all flaps and doors
  • Remove SD Card
  • Dab off any obvious water inside camera or compartments
  • Put camera in a large plastic bag with desiccant packs or similar
With time the camera should dry out with (hopefully) little or no damage to the electronics. Removing the battery is critical. If desiccant packs are not available, some users have had good luck with uncooked rice, frequently changed. Your lens will probably require similar treatment.

I am sure other users will add their advice.

Sounds like a button might be stuck in the pushed down position due to moisture?

Thanks, some useful advice from one Steve to another! I've done all the above apart from putting the camera in a bag with desiccant. I'll do this now and similarly for the lens. Hopefully my camera will be back to working order and I'll report back if it's successful.

Hi Adam, are you referring to the shutter button? If so, will drying it out free it or will I have to gently pry it free?

Sounds like what happened to me. I wrote about it under k-s2 sub k-s2 and an interesting case of non wr lens. Camera is fine but took weeks. It still took pictures but i couldnt change ISO (backbutton). I only used a manual lens at the time so dont know about autofocus.

I'd leave the whole camera in a bowl of rice to suck out any mosture. Hard to say where it could be!

Hi all, a quick update. It appears the shutter button was stuck, after some gentle prying with some tweezers everything is working as normal again. I'm leaving the camera to dry out some more for a few days as an extra precaution. Thanks for all the advice, there is now one less panicked herpetologist in the world!
