No offense, but its a K-x. How old is that camera? How many photos has it taken and where has it traveled? Unfortunately, digital cameras don't have as long a life span as older SLRs did, and even a little defect can have a big effect on the image. I know there are some people still shooting with even older digital cameras and produce amazing images, but its not that unexpected.
That being said, you can try doing things like turning SR off, using a remote timer, making sure the lens/mount contacts are clean, there isn't any dirt on the SR mechanism, even reverting to an older firmware.. Hopefully it will work out for you. You can also think about getting a cheap K-01 - it has better IQ output and might cost you less than repairing the K-x.
