K-x malfunction, any similar experience?

Ever since I got my K-x, it's constantly producing unsharp images at low shutter speed. Today, I finally decided to do some analysis with my xxx algorithm. After some comparisons I finally found my K-x is faulty.

The problem seems to be related to the mirror box. The image will be more blurry using the viewfinder than using the liveview mode in every mode, even with SR turned off. Thus my conclusion is the fluttering of the mirror box seems to have affected the CMOS when using the viewfinder.

Here are some 100% crops of the blurry images. I took 7 photos of the same scene at shutter speed 1/100s -1/125s with the viewfinder, unfortunately none is clear.

And here are the corresponding blurry path:

The point is: if the image is simply mis focused, the blurry path, or kernel will be like the shape of the aperture, it sure isn't the case here....

EXIF:

Anyone knows how the repair will be like?
