Thin green line on K-7: problem solved!

I am one of those with a thin green vertical line appearing when camera temperature of the K-7 is above 32°C.

I contacted Pentax once more yesterday to ask if the analyses of the problem did come to any result and how to continue. I was told to bring the camera back to the shop who will send it in and I will get a replacement K-7, but before rushing to the shop, I could try to update to firmware 1.01.

I told them that I updated to 1.01 on the very first day the update was released and that it did not solve the problem. They told me to download the firmware again from http://www.pentax.de/de/product/17531/body/downloads/digitale_spiegelreflexkameras.php and to install it.

Well, I was surprised, but did the update. Then I tried to heat up the sensor by using liveview and video and took regularly a few high iso shots. Even at a reported camera temperature of 36°C, the shots did not show any single green line, not even at 2000iso.

I compared the exif of the raw files using PhotoME and found the following differences:

K-7 with 1.01 showing the green line problem:
DSP Firmware Version: 1.01.00.*05*
CPU Firmware Version: 1.01.00.*05*

K-7 with 1.01 of yesterday, *without* the green line problem:
DSP Firmware Version: 1.01.00.*09*
CPU Firmware Version: 1.01.00.*09*

For me, this firmware update solved the problem!

Those having the problem can try this as well.
