I know what you mean about the polarized lenses, but I wasn't wearing them.

I tried checking the firmware, but the screen won't even show me that.

I have a K10D that I turned on one day and the display stopped working. It is completely black-It won't playback or show any info whatsoever. When I hit the play button, the orange light on the bottom right lights up, but nothing happens. I have tried new batteries and a new card. I also tried changing the lens. Please help!
