I just did the Pots adjustment as Sarge described (set_up clockwise all the way and Vs one tick counter clockwise)....and what a freakin' difference! It is not perfect inky black like, but damn is it noticeably better.
Holy Jeebus. By a good amount too. It looks like there is more "depth" in the picture. Not necessarily more details....just a lot more natural than before. I wish I can explain it better but it's beautiful. As for my settings, I am using Cinema mode with contrast at 60 and everything else 50. I tried BN's settings but they just don't look right on my TV (loss of details). I might try BNs settings again (might have made a mistake inputting them). The adjustments are ridiculously easy to do...and much faster when you have help!
First off there were 3 more screws I had to remove compared to the diagram in the training manual on one of the links posted earlier. There was a small screw at the top center of the back cover, and 2 more screws at the bottom near the stand (1 on each side). There are different size screws so be careful not to mix them! I printed out the diagram that shows the 29 screws and literally taped each screw to the arrow on the diagram not to screw it up.
Second, the Vs pot is slightly different than the set_up pot in that it is a cross with 2 dots beside one of the arms on the cross. I adjusted that counter clockwise 1 tick and ran some color slides. Everything was perfect.
Third, the set_up pot has an arrow which was turned clockwise all the way (which was barely 90 degrees...the arrow points to around 2 o'clock for me not).
I was able to remove the back cover without taking the TV off the stand. The swivel stand came in handy big time hehe. I unplugged the TV just in case and only turned it on after the adjustment was made.
I'm going to play some PS3 and XBOX 360 tonight then pop in a few movies tomorrow.
Sarge and all, thanks for posting this adjustment! I always loved the colors of this TV and now it's so much better! It is too difficult to capture the color difference on an iPhone camera but I will take some pics when I have a chance to try to show the deeper blacks.
I feel like I have to rewatch all my movies again! Can't wait to see my wife's reaction...if she notices a difference then that says it all hehe.
