My k-50 has the black picture after 3 years, i bought IT new.
To repair IT costs 190 euro.
My camera is in germany at Pentax.
There where 3 problems i cant all remember. Diafragma failure block, fireware and onother thing.
Really dissapointing. So what is a good replacement without this problem. K-70?

Hopefully once you get it back you won't need a replacement. If you were considering something else I can't think why you would pay out to get that one fixed.
Welcome to PU by the way!

A second camera is always useful, JAK.
This what happened to my K-50 - so I got it fixed and now it's a second camera as I got another camera in the meantime.

The exact same thing happened to me, got my K-50as a birthday present two years ago. It's been working fine until last week. LiveView worked fine, not darker than usual. But the pictures were completely black or very very dark. Googled around a bit and did some trouble shooting so I got the same as many of you. It seems to be an aperture control block failure. I fired of multiple shots in speed mode and it started working again. So like for the rest of you it'll also stop working again.

Lucky for me I have an old lens with an aperture ring, Hopefully I can just use that one instead and continue to use the camera. I'm not a rich lady, and I just passed the warrant expiration date so I guess I don't have much of a choice. I read that some of you have been reporting the failure, getting in touch with pentax and using the pentaxcamerarepair.com team. But I live in Sweden and the shipping costs are huge.

It's just something to accept unfortunately. Good luck everyone!

If it's only just out of warranty contact your dealer or https://www.ricoh-imaging.se/ and see if they can help.

I second that suggestion. Some good Pentax dealers seem to be able to persuade Ricoh to repair free of charge even if warranty has recently expired. I am grateful to our friends at SRS who managed to have the aperture block failure on my K-S2 repaired free when the fault developed 2 months out of warranty. That was about a year ago, and the camera has been working well since then.

Could anyone point me at an online source for the exact aperture electromagnet - preferably of decent quality - to fix the ubiquitous K50 problem? Got lots of time on my hands to do this with care and attention to detail just now!
Thanks very much for any assistance.

Thanks, mainly asked as I had the fault repaired a few years ago by Johnsons Photopia but before it was recognised as being the solenoid issue. Assumed it might be viewed as a standard repair now it is more widely known and somewhere doing it for a fixed price. I'll contact John Pye.

If you have some precision screwdrivers this is a repair that most people who are reasonably handy can easily do themselves. There are loads of youtube videos on how this repair is done and also the solenoids are in ready supply on ebay. Alternatively, you may be able to fix the existing solenoid in the camera by shaving off the shoulders with a small file, again there are videos on youtube showing how this is done. Taking apart a K-50 is pretty straightforward, as it is with most of the Pentax DSLR's, the shells come off easily when you've removed the right screws. You need a screwdriver that is a '00' gauge crosshead.

I second the procedure above. It's something that can be done in a couple of hours with a Youtube tutorial running in the background.

Just remember to use a loop of tape to put your screws on as you remove them. Even better if you write 'front/left/right/rear/bottom' on a bit of paper so you can remember where they came from.
