Anyone notice my dead pixel in the middle left? Anything I can do about it?

Looks like a hot pixel on your sensor, did you try remapping it using "Pixel Mapping"?
Also, does it shows up in the images too?

Well I can't see any hot or dead pixel in that clip. I paused several times a different intervals, looked closely but could find nothing that stood out as a problem. The sensor noise was all I saw.
I use 'Splayer' to view video clips on this PC

Hot pixel

Had trouble finding it as well, but it's there. Try using the Pixel Mapping feature that Swapnil suggested. These buggers can be quite annoying.

Not that I can see, just took two photos with the lens cap on.

Is there something else I need to try to test?

Strange!

Not sure if you want to get it repaired by service center or use some software to correct that

I'd try calling Pentax first. It seems very odd that the Pixel Mapping function would be ignored in video mode.

tried calling Pentax, the respond was "we dont bother repairing cameras if its only one dead pixel" so now im not sure what to do seems to me that having warranty means nothing. If anyone got any suggestions please let me know

Thanks

can anyone help me as to where i can locate my recorded video? i dont know what happend it seems like it was "erased" in my file.

after recording a scene, i do made some replays in the video.. and after watching it, i immediately switched to the setting into M(manual) so that i could continually take pictures.

i review the file in my camera for several times but couldnt find it.

is there possibilities that it wasnt saved at all after taking the video in-spite that i was able to review it or someone erased it in my Card.

please help. thanks!

:-(

Pixel mapping affects only images, it doesn't work with video. That's the reason why you have bad pixel visible on videos. This thing is rather unrepairable and you have to live with it
You have only one dead pixel, I have two and both of them are in the center of the video - not a very best place to see a dead pixels ;(
