Hi Pentax friends,
Randomly have issue with my K-50.
Most of the times, the pictures are plain solid black.
Other occasions you can still see a "picture" but the colors are corrupted to the point where only 2-3 colors show (see picture), making an almost unreadable picture at the end.
The Live View on LCD already exhibits the issue before taking the picture. (i.e. I turn on camera, turn on Live View and the display is all black, or more rarely showing corrupted colors). (Yes, I did remove the cover on the lens! if you're about to ask

)
I've browsed the forum and of course came across the "aperture block failure issue" but I don't think this is my issue (reason is, the lenses are not part of the equation, even without any lens attached I see the same behavior on the LCD)
- The mirror mechanism does work.
- Upgraded to latest firmware, no change.
- Charger battery fully, no change.
- Tried a few bursts of continuous shooting, no change.
- Anything else to try ?
Sounds like a defective CMOS to me but curious to hear your thoughts.
Thanks for reading!
Hugo
