HELP ME! Black images

First time posting here. PLease bare with me.

Last two weeks my k10d broke down. First it was half black half coloured picture. After that, only black blank images were produce.

Now, i just bought a second hand k-7.

All good for 3 days, suddenly just now, the same thing happened. The hell!

Live view all black.

I used the same card n lens during both incidents. Swapped cards n batteries still the problem is there.

Help me! Ive tried reflashed the firmware in k10d. To no use. And i doubt it would do good for k-7.

Pentax have failed me twice. My wedding job is next week.

Yes. :ugh:

One thing ive noticed is that, in both bodies, when i put the "Sensor Cleaning" on. I can see both sensors are covered with some kind of black layer. "Window`s blind" look alike.

It looks like that things is stuck onto the sensors.

Anyway to manually released it?

Btw, what do you guys think the main cause of this prob? The lens or the sd card?

Looks like the shutter that covers the sensor may be jammed.

^^^^^^^^^
What he said. That's the shutter you are looking at. It should be opened to expose the sensor in cleaning mode. It is VERY strange that it would happen with 2 different cameras at the same time. What have you been doing with these cameras?

Have you tried different lenses? Is there actually a file being recorded (JPEG, RAW or both?) If so, can you PP the RAW and increase the exposure to as high as possible? I'm curious if photo is actually being shot but severely under exposed and coming out black.

I don't have any experience with this type of problem.
However I am wondering if you have used another brand lens that
extends too far into the camera thus causing shutter damage in both
cameras? What happens with the kit lens if you have one?

Yeah. Looks like it. Tried frcing it down on my k10d. Succeeded but when taking pics again. The shutter will again be jammed.

I dunno. I thinking the culprit maybe the memory card. :ugh:

Yes, check the card. That should be the first thing (easiest thing) to check in situations like this.

I don't see how it could be the card. It seems to be saving the file recorded by the sensor. Looks like the sensor is being blocked. Could be the shutter is not opening or the mirror is not flipping up when an image is captured.

the shutter curtain in not move down. when i set to "Sensor Cleaning". the sensor is covered by the shutter curtain.

it puzzles me which may cause this problem. impossible shutter died on both camera suddenly. must be either the lens or memory card causing it.
