So I just thought of something... When 99% of us first did the logic fix things seemed to be pretty good for a few months after. Would it be possible to revert the set to before we did the logic fix and then just reapply the fix? Perhaps that will give us another few months of pop-free viewing and then we can just continue to revert and reinstall whenever the pops become a problem. It isn't an ideal solution but I would be willing to do this every few months to be rid of the pops.
Can anyone weigh in on this?
Interesting idea. Logically, I would assume this would work, assuming that it could be fully reverted back to the original firmware (logic board included), without any lingering traces of the updated firmware.

This is night viewing under controlled lighting and central air maintaining a constant ~73 degrees, no changes in settings.
Can't be done, the logic board update portion of the firmware fix is permanent. I see no reason to think this would work anyway.
Understandable that it couldn't be done. However, if it could be done, I see no reason why it wouldn't work. There's a pretty hefty data set of users whose pop problems disappeared immediately after the firmware update, only to gradually return over time.
Zoyd attributed this before to the users' increased sensitivity to the pops, meaning our sensory thresholds had realigned and were now able to detect the smaller, "remnant" mini pops. I accepted this at the time. However, there is no doubt now that the original pops have returned in their full glory and magnitude. Scenes in movies that originally had the pops, which were then eliminated right after the firmware update, have now had the pops return.
A bit conspiracy-theoryist, but I wonder if Samsung created this "fixed" firmware to eliminate the pops in the short term, only to have the TV gradually, softly ease them back into the set over time. Some may say this is ludicrous, but what other explanation is there? How in the world would these TVs be dynamically changing the picture like this over time? (besides the obvious gradual change in colors and blacks representation over the set's life hours)
Perhaps I've overlooked the discussion on it, but has there been any confirmed (or hypothetical) explanations of what the pops' purpose is? Why does the TV do it?
I've postulated before that it's as if the TV's eco-sensor is stuck permanently "on", perhaps as a form of burn-in avoidance, or as some type of energy-reduction. If anyone wants to see the effect drastically, hook up a computer to the TV over HDMI. Have something across the entire screen that varies in dark and light, like a desktop image or a full-screened picture. Now open up a folder window. Grab the top title bar of the folder with the mouse, and drag it up and down the screen rapidly (if you're on Windows 7 and you rapidly shake it from side to side, it will minimize all the other windows).
You should see the obvious, dynamic darkening/brightening of the screen. Additionally, and at least on my set (across all three set replacements I've had, including the most recent panel exchange), you should also see obvious banding streaking out horizontally from the title bar of the window across the screen.
Here's another way to see it: disable all miscellaneous functions of dynamic contrast, eco sensor, noise reduction, burn-in protections, etc. Then leave some kind of static image on the screen, like an unchanging computer desktop, or a paused video game or movie. A computer desktop or paused video game work best.
If there is a static image on the screen, you'll notice that the entire picture gradually begins to darken, almost if the contrast or cell light is being reduced. After 15-20 minutes, take the mouse pointer and click on the title bar of a window. If you move the window very slowly, the picture will stay in its darkened state. But if you move it quick enough, the entire picture will snap back to its original look. Same thing with a paused video game or movie. Once you unpause and a character or something in the picture changes beyond a certain degree, the image snaps back to its original look.
I'm no expert, but I would guess that this effect is somehow correlated to the fluctuating brightness. The TV has some sort of picture dynamics forced into it, no matter what features are disabled. Oddly enough, these "features" are far less pronounced and obvious, if not done away with, in the TV's "Standard" mode. Is it a coincidence that out of all modes, the Standard mode is the only one that cheerfully advertises with an icon that it's Energy Star compliant? Again, I'm no TV tech or engineer, so I'm just throwing hypotheses to the wind. Pardon me if this has been discussed and narrowed down to specifics.
When the tech adamantly professed that the brightness pops I showed him were the movie/media's fault, I showed him the blatant effect through this method. He attributed it to the computer, which obviously doesn't do it on any other monitor or TV screen (verified).Edited by coldblackice - 8/28/12 at 12:27pm
