Out of curiosity, is the red stripe across the top a feature of all the bad frames?

That's probably from the strip of masked dark pixels that surround the active, light-sensitive portion of the sensor. The camera and post-processing system use the measured values in these pixels to estimate the black-level of the sensor.

If so, the problem must be very severe.

Grasping at straws. Could you do a firmware update?

SteveBrot - Have not noticed striping on any of the previous images and I don't have them as I deleted them.

UncleVanya - I applied the latest firmware so it's current

I should mention that I've had the camera for about 8 months and this has happened about 5-6 times out of a 1,000 images taken.

Service center, anyone recommend one, I live in Southern California.

Thank you all for your input. I'm going to do some testing to see if I can replicate the problem, i.e. listen to any anomalies when the shutter is released for example.

I'm simply stumped. This is a weird issue.

Is the camera still under warranty? Do you enroll in the Silver or Platinum Service program? If so than Precision Camera in CT is your only choice.

Picture Perfect in Valencia, CA used to be an authorized Pentax repair center. They may well still be even though not listed by Ricoh, as is the case with Advance Camera in Oregon. Regardless, Picture Perfect no longer takes walk-ins and only Precision handles warranty service.
