K100D Super sensor problem

Hi, i have this problem in most of pictures from my K100D Super, there are darker stripes, mostly in shadow and midtone areas, as you'll see in the attached photo (100% сrop). Anyone had this problem? Seems to me that sensor is dying..

This picture lacks Exif info.
What ISO did you use here?

These lines are horizontal, (a picture is rotated). Exif info below:

Model: PENTAX K100D Super
Serial #:
Firmware: K100D Super Ver 1.00
Frame #: 1292
Lens (mm): 50
ISO: 800
Aperture: 1.4
Shutter: 1/90

Could it be that contacts between sensor and the main board need cleaning?

Banding should not be a problem at ISO 800 at all.
You can see the pattern also in the lighter areas.
Sure you did not cranck up an underexposed picture a lot in post processing?
Did you try another SD card?

If not, looks like a serious problem to me.
You are still on firmware release 1.0
For some camera's updating the firmware helped dealing with banding problems, but I've never heard of such thing with a K100D Super.

Sorry, Bert

Is any of this visible on the lcd at maximum magnification? What image format and software are you using?
