K-7 Returned with faulty sensor
John, you might have to turn up your contrast/brightness. It runs down the centre of the image from top to the bottom and is only ~1 pixel wide. Tel, I've just sent it back to SRS for a replacement body.

K-7 Returned with faulty sensor
That's very disappointing for you, so I hope you get your replacement soon. There's nothing at all showing up as a green stripe on my monitor though - where is it? Is my monitor too dark to see it? Yes your screen must be, go from the left move to the mid way point then just on the right side of ...

K-7 Returned with faulty sensor
I put it into Photoshop and with the brightness increased substantially it becomes visible at 100% and above. But it is definitely there and, as you say Chirpy, it's about 1 pixel wide.

K-7 Returned with faulty sensor
BTW, I do know that the photo I posted is under-exposed, that is intentional to more easily demonstrate the problem. It can be seen more faintly in properly exposed images as well and is quite visible with macro shots at 100% which is a pain for me as I often heavily crop.

K-7 Returned with faulty sensor
Sorry to say this or your eyes are getting a bit old, green colours are the ones to go first. Even with my eyes I know that both aren't the same, the green with the right one is mostly greener while the left one is a bit more brown :? I can see the line clearly too does it stay there if you turn...

K-7 Returned with faulty sensor
I can see the line clearly too does it stay there if you turn on and of the camera or even reset it and does it do it all the time after video? It stayed in the same place. It seems related to the temperature of the sensor. I tested with a short video and it was fine. With a longer video is showed t...

K-7 Returned with faulty sensor
This reminds me of a problem I had a couple of years ago with my K10D. I was getting lines across the image. Eventually it was traced to my computer - presumably the graphics card. Somehow, when saving the picture to the computer, lines were being added. A new computer solved the problem. S...

K-7 Returned with faulty sensor
George, I remember that happening. My main doubt with that is that the problem is reproducible only under certain strict conditions rather than a general intermittent or continuous problem under varying circumstances. Prior to playing with video I have shot several hundred images, none of which show...

It stayed in the same place. It seems related to the temperature of the sensor. I tested with a short video and it was fine. With a longer video is showed this problem. It does go away after a short while, presumably after the sensor has cooled down a little. I didn't try a simple off/on again. Part...

K-7 Returned with faulty sensor
I've read elsewhere that this is showing up on a number of K-7's. Amazon US are said to have returned all their stock to Pentax because of the number of complaints they were having to deal with. Suggestion is that the problem was confined to one early batch of cameras. Somehow thought to be assoc...

Yes, I'm not suggesting it's the same problem, just that it pays to consider all possibilities. G When I get the replacement and test I will be sure to use a different PC as well to rule out as many things as I can. I did check with two different makes of SDHC card to that end.

I did read some where about the reason for the delay in the K7 release was to do with temperature problems with the sensor, so it may not be cured yet.:(

There is some stuff about this on DPreview - the line shows up after doing some video, so seems to be linked to a temperature problem Andy EDIT: probably following use of liveview. The DPR forum links across to a discussion on pentaxforums

Jonathan, sorry to hear your K-7 has developed this problem. I think ours must of been from the same batch that SRS had. So far (touch wood) mine doesn't exhibit the same issue. Having seen your post I gave mine several 5 minute cycles of live view and video and it seems OK. Anyway I hope your re...
