press "062596" then the "info" button on your remote (gotta do it kind of quickly). After that, hit the red button.
You are now in the service menu.
Go to "Alignment"
Then go to "White Point"
From each temperature setting (Warm, Normal, Cool) there are these settings that you can change: white point red, white point green, white point blue, red bl offset, green bl offset.
The default for the offsets are: red bl offset=5, green bl offset=6. As you can see, the green bl offset is set pretty high. Last years model was red bl offset=7, green bl offset=3.
Anyway, BE SURE TO WRITE EVERYTHING DOWN FIRST before messing around =)
