I am convinced there is something else going on with the WB METHOD 0 setting besides the way it stores the colour temp settings. I say this beause I was watching TV last night and found that my whites had turned a sickly pink/red hue. I couldn't figure out the cause as the whites looked fine while in the service menu, so I tried setting it back to method 3, restarted the TV, and presto whites are back to normal! Needless to say I was hugely relieved
So it seems that changing WB METHOD while in the SM doesn't have any effect on the picture, but outside of the SM there is a difference (in my case, too much red in the whites). In light of this I would say it's probably best to set WB METHOD to its default value 3 before exiting the SM.
I also came across this post in another thread:

After several runs, you do get better at making the changes though.
Looks like calibration is going to be a massive pain in the ass.
Please let us know how you go PlasmaPZ80U.
