Well after two short years I have to retire the 'ol K-7.
Did a firmware update and now I get a horrible horizontal black and white spotted line (I'm devastated),
right through the middle of all my images (except video). I believe it's the chip and not the censor BUT...
the cost to fix either is so high I decided to just upgrade to the better Pentax K-5, Just ordered one
(fingers crossed it's a legit place)?!
So no new pics until the new rig arrives
Very interesting, never heard that one before.
In the video, when Hummel said that "gamma rays don't hurt us," I knew there was something wrong. Gamma ray dosage of airline flight crews are sometimes used as a baseline for human exposure [see nuclear plant incident in Japan].
From the linked article:A dosage of over 6 Grays would be a death sentence, so even if that study is off by a factor of 100, it doesn't seem possible that sensors are being affected but not humans.Delving into the numbers, a 2002 study about the effect of Gamma-ray radiation on color CMOS image sensors, like those used in many DSLRs, showed 600Gy (Grays) would kill them, but a 2008 UN report about the effects of radiation on people points out that the average annual effective dose of overall radiation for airline flight crews, including gamma radiation, is only 3.0 mGy (Milligrays).
You may want to see if you can factory reset your bios back to default Scum.
Sometime "upgrades" are not really all that "up", and few RARELY damage a camera/system.
So the first thing to do would be do a look up on the help file or online for how to do a factory reset.
See if it works. If it does, keep going.
Try re-flashing it to your new Bios/OS/Firmware and see if you have the same problem. If it works now, you may have had a problem with the upgrade itself (not clearing and installing properly).
If it STILL does not work (but worked on the reset), you can try to download a new copy of the firmware OR look around for the older copy you flashed before and use that instead.
I hope you bring that puppy back!
The problem IS the firmware upgrade...it corrupted the chip (not the censor) already had it looked at.
It must be sent back to the factory to be reset. The cost with shipping is over $250
plus it will take months...not worth it for me.
I have already purchased a replacement - the Pentax K-5 , if the e store I bought from is legit I should have by sometime next week)
It's a far superior camera and this was just the excuse I needed to trade up.
And by the way- that "part of the pic" - was meant to look that way- and was taken long before the problem showed up
I took pics not 3 minutes before the update- all fine.
First one after- affected...and all since.
Here's a pic with the chip corruption- notice how it's not the same all the way across.
WARNING: If anyone is thinking about buying a camera or electronic device, stay away from digitechard.com!
They run a very clever and convincing scam site- reported them to the BBB and their local police (don't ask).
TIP: if buying online, make sure the joint is BBB certified and avoid the hassle.
new photos with the better camera can now be found here:

SM, I see the line there, but I do not see anything els.
Not that that is not enough to ruin a pic, but is there something else I am missing (color balance?).
It is a shame you need to send the chip in to be "reset" and you can't do it yourself. So many other electronics have ways to dump any firmware upgrades and go back to the original config, it is a shame that this does not.
The ONLY thing I have heard is an incorrect upgrade (unrecoverable) "brick"ing a component (turning it into a paperweight). Either way, I am sorry that happened. You would think with a "premium" piece of equipment you would not have to worry about stuff like that.
Scumonkey you take beautiful pictures, I admire your work very much.
