I'm going to take a wild guess and say that something inside it broke and that it needs to be sent in. Probably a serious sensor/circuitry problem.

wow...interesting.

I'd try different battery, different SD card...and if you confirm it's consistent, then it surely is something on the sensor or one of the boards. As Adam said, send that puppy in....

Good luck,

I think it is a malfunction or perhaps catastrophic failure of a component part, or parts, and/or associated circuitry.

I have two battery (I have BG2), and two SDHC Transcend, one of them class 6. I think to buy SanDisk Extreme III, because with class 4 I have very often problem (6-10 normal shot), with class 6 not to much (per 100 good shots 2-3 bad).

Get a quote before sending it in, repair charges are usually double the cost of a replacement.

Mine did something similar, started with green bands on a few images (amongst lots of unaffected images), then a green image and nothing I could do would 'fix' it.

New motherboard. Sorry.

I hope you have some warranty left ...

I used to get the freezing camera & corrupted image with a Kingston Class 6 8GB SDHC. Had to remove the grip and the camera battery to get it to work normally. After switching to a Sandisk Extreme 30mb/s 8GB SDHC (and subsequently losing the Kingston card) I haven't encountered it since. I emailed Pentax before but they told me to try it out with a different card and without the grip. If I ever run into the same problem I'll send the camera in for a checkup.

I have talked with two different services centers of pentax where one of them told me that this not a matrix, and not a sdhc card and nothing else. Second told that this happened only when water inside. But to clear situation told me try to use only SanDisk and if this happen again send it to service.

p.s.
advised to forget about Transcend
