K5 LV/Exposure goes black

Hi,

Tried to search the forums for this but can't seem to find a answere.

Lately my K5 started to produce black exposures. Everything else seems to work ok but the picture is all black as if the lense cover is on. (Its off)

LV is also black and exposure/aperture/iso flashes red (as if cover is on...)

Have been able to resolve this before with removing the battery and a short wait but this time the problem persists.

Firmware is upgraded to 1.15 I belive.

Any suggestion is welcome as I am on holliday and would love to take some nice pics!

Btw.. Problem comes with any of my Pentax lenses.. Right now the 21mm limited is mounted.

Velkommen!

Sounds to me like your mirror is stuck. If you take off the lens, then go into the Menu, on page 4 of the Wrench menu and choose "Sensor cleaning" you should see the mirror lift up. I don't know if it's safe to try to help it a little (very carefully!) if it doesn't lift by itself, but that's the only suggestion I am able to come up with.

Maybe try to upgrade the firmware to 1.16 just to see if that can clear away some bug if it's a software thing, but I really think it sounds more like a hardware problem.

Another idea is to see if you can locate a camera repair shop where you are.

I really hope you're able to sort it out!

Hi, thanks for the input!

The mirror move's fine, but it seems like the curtain infront of the sensor is stuck. Don't know if it is safe to try to move it manualy?

Oh, so it's the shutter that is stuck then. I have tried to google it, but can't find anything that a battery removal didn't fix (well, "fix"). For some older cameras with jammed shutters I see some advise to gently "help" the shutter curtain along. I might have chanced it if something like this happened to me in the bush where the pain of lost shots would be really high, but perhaps not if I were on a beach holiday closer to home... On the other hand, it would annoy me beyond belief if I went through an entire holiday with a stuck shutter just to find out that a gentle push would have solved (or eased) the problem.

Sorry I can't be of more help

Just a quick update incase someone else will experience the same problem. The camera was serviced without costs by Pentax even thou outside the warranty period, seems like this is a know issue.
