Is this just a coincidence or Pentax/Hoya has already succeeded to use the firmware to *hide* the lighter vertical line (not always in "green" colour actually, read here for some of the previous bug reports by different users and the details)? I think time will tell.
But since this is very possibly a hardware issue, I don't think software (i.e., the firmware) can completely "cure" the problem. Even if the line does not appear now with the same camera (i.e., the hardware), the software could only do tricks to hide it when it is detected! Who knows if there is any loss of image data as a result? E.g., by simple interpolation using the data of neighbourhood pixels around the line.
However, as long as Pentax do not officially announce that there is a new firmware to "cure" this well-known problem now, such an individual user report on how possibly a "new" (still in version 1.01) firmware is the solution to the issue may be just not so conclusive and it is indeed too early to draw a conclusion like that. In fact, have Pentax/Hoya ever admitted that there is such a problem so far? .. even though it has been widely reported and proven - there have been so many samples posted to illustrate the issue already.
Update (10-3): The Green Line is Persistent!

The user writes that the latest firmware 1.01.00.09 actually does NOT solve the problem. A green line will appear whenever he uses the Live View function, regardless of the temperature of the camera (which is recorded in the EXIF).
Update (10-9): The Green Line is Persistent! (But it has been reduced.)

What will happen when the photographed object really present a green line. It disappear?
Sorry for my English

You clearly have no idea of the cause of the problem, yet you complain when a user seems to no longer have the problem after a firmware update. Why do you do this?

I am commenting because I personally don't find it acceptable for Pentax to sneak out another v1.01 firmware and deliberately kept the timestamp of the time unchanged. I don't know when exactly they did this but I hear it happened not long after they released the "original" 1.01. So except us early adopters, there should be plenty of people that did not get to download the "original" file.
It's a shame that Pentax chose not to be transparent to users about this because if this "newer" 1.01 indeed contains fix for the alleged "thin green line" issue, they should communicate it widely in order to avoid users that encountered the issue go the hard way, which is to have their camera exchanged to a new unit. I know someone in China that did this soon after his purchase. The original poster on dpreview, tcom from Switzerland, said he told Pentax he updated to v1.01 and was told to re-download and re-apply the update. This clearly means Pentax staffs in Europe know something and they know it quite clearly.

or maybe must be a problem so you can jell on something
quickly you have to find k-7 without(or with, am confused) problem and count pixels, ask Horatio from CS Miami to help you count

Pentax has not listed all the fixes in the firmware upgrade, it states fixes for more stability issues, and gives an example of this (the "left AF sensor issue") and does not dig deeper than this. This actually means that there are more fixess. Does Pentax really has to go into detail about all the fixes, as long as there is improvements?
In todays world of photography, cameras are fixed by firmware upgrades. The others do it all the time.
And more will come...
I see it as positive news that Pentax are fixing things. They may not fix all things at once, but there will be more firmware upgrades. Of course in an ideal world the K-7 would have been perfect from the start. However, just like Canon and Nikon and Sony, there will be firmware upgrades to fix problems.
Today, all the makers releases cameras a bit too early. It is a sad development, but Pentax simply follows the others.
Now, I can assure you that there will be several firmware upgrades to fix problems with the new Canon 7D too.
Just like every other Canon DSLR in the past.

c'mon RH be honest from other manufacturer even raw is not true raw anymore, there is a lot make up on image despite u want or u don't want that, so at the end we are back to my statement, if u have image without problem there is not problem except in your head, or in ego if u are insulted by that device doesn't work in way you want to work.
I just see nikon and canon sites with firmwares, from minor to major changes from version to version and that is normal

I was in contact with Pentax while they worked to get the vertical line issue resolved. You could have contacted me for further details before publishing your blog article. It took them about 6 weeks from first bug report to resolution (the fix you are writing about is a couple of weeks old). Not bad at all. We all should applaud Pentax engineering for the achievement. I know that they took it seriously and worked hard to solve an issue only affecting a few of us.
And it is not a "hiding" of the issue. Pentax doesn't publish the root cause. But from all what I know it is a real fix without any negative impact on image quality. As only a very few number of bodies is concerned (according to Pentax), the fix will be announced officially with firmware 1.02. The current hotfix was meant for premium dealers and a few customers calling in or reading the internet.

Software can control the hardware, e.g. biasing the sensor's voltage so it works at the proper operating area. It's like calibrating the signal from your VGA card to your monitor for best display and color accuracy.

I saw this cat last year, can't remember where but it was grey, I have no further information.
Rice, could you tell me the address of the owner for me? I'd like to get a photo of the cat.
You seem to be able to deduce similar conclusions with limited information about Pentax and their designs.
You must be one hell of an Engineer.
Being an Engineer myself, I have no idea how you conclude what you do with so little facts and yet, you are so sure of your own conclusions. I mean so really sure its scary.
Engineers don't like to make claims until they sure. Till they are so sure that they know the answer that they would risk their balls on it.
I think you must be the eunuch of photography time and time again based on what I've read here today.
You should appeal well to other ignorant people willing to believe something based on speculation and conjecture.
If anything, you make informed people want to go support Pentax.
BTW, I know people that have Canon's and Nikon's that are pro versions, yet, for some reason I seem to get photos they can't.
Must be the faulty equipment I'm using.
It surely has nothing to do with the fact they have no idea how to take photos, does it?
Add some credibility to your words, show us all some pictures you have taken so we at least know you are a decent photographer rather than having to just accept that you're a lousy engineer.
