I'll take a chance ... count me in! I love my current Pentax (K20D from 2009), but a free upgrade is always welcomed!

Sorry for the delay. I sent it in for warranty repair (covered by my CC provider -- thanks Citibank. Sorry for the shameless plug.) They ended up replacing the sensor all together. It has been working fine since. I hope you have good luck finding a solution or servicing it!

glasbak -- Bingo! (sorry for the delay of this response). The sensor is indeed still giving a response, regardless of the shutter time. The very far left R/G/B is 9/2/6 and approaches the anticipated 0/0/0 near the center.
Is this fixed only by a sensor replacement or is there a way I can recalibrate/zero the sensor to reset it?
Thanks again!

Thanks for the additional detail -- I will give it a go this evening. If I am unable to determine it, I will post the RAW files if you are willing and able to take a peek.
Thanks!

Thanks everyone for the feedback and input. Some response:
paperbag846:
I see nothing on the sensor itself -- but that is not to say minor moisture or something is not there. Given it's perfect vertical stature, I am guessing it is not something on the sensor. If I feel up to it, I'll give it a cleaning this weekend.
glasback:
I did some more additional testing and I found the banding does seem independent of the shutter time (Hind sight, I suppose this is why I could see it in live view). I took pictures with the lens cap on at 100 ISO as suggested, but the pictures came out pure black with no banding. Is this what you would have expected or were you expecting the picture to be banded with the lens cap on?
Eric Seavey:
You are suggesting where I was with the bad sensor. Not what I wanted to hear, but I am happy to know that Pentax might have promising customer support and extend or repair the camera for free (reduced cost would be great too!). I will contact them in the next few days and see what they can do to help out.
Marc Sabatella:
Unfortunately it is not a fluorescent light problem as it is observed in my outdoor pictures as well...I first observed the problem when I was in northern Michigan taking pictures of waterfalls. Great idea though as I was not aware of color cycling.

I am looking for some assistance with my K20D. It is 3 months out of warranty (go figure) so I am looking for some input from the experts and enthusiasts here. In the past week, I have noticed some discoloration in my images -- consistently on the left side of the image where the image is darkened. Some details that I think would be useful to know:
1) The problem occurs on various lenses
2) The problem cannot be seen via the viewfinder.
3) It is observed when using the live view (open shutter).
4) I have tried various ISO / apertures / focal lengths
5) The problem is observed most in darker scenarios, but does exist in well lit settings.
I have included two images below of a wall in my house (with and without flash). The wall is a solid color (light blue). The problem is observed by noting the vertical divider (a horizontal gradient) to the right of center.
I am thinking I am looking at a sensor that needs to be replaced, but I am looking for opinions, information on if this is common (or even has a term), ideas on how to correct this problem, or a confirmation on my sensor thought. This problem does not seem consistent with dirt/dust dark spots, but I have not ruled that out with a cleaning yet.
Thanks in advance for any assistance and taking the time to read this post.
