I don't think I've ever had a customer call because their Toshiba is
too green. I sure can't help but notice it when servicing the set.
Maybe I'm right and many of them (not just in my area obviously) are
too green and even some of you techs see the colors differently, or
are just not that picky (same as the customers, and the guy at the
factory).
Whenever I say the picture's too green, my partner usually agrees
(but doesn't see the green as much as me). Customers always like the
picture better when the blue is cranked up to produce a better grey
scale.
