In the 42" Westinghouse thread they changed RGB settings and say that skin tones and colors look better. Trevor, what settings do you have, brightness, contrast, hue ect. Do you use component? Thanks for your replies.
I've seen people post various numbers for their displays, but that is at best a highly unlikely approach to optimizing your image.
Since you specifically ask, here are my current values for four of my viewing modes (I've now had the set for about four weeks):
HDMI: 49 Brightness
YPbPr1: 50B, 63C, 66S, 50H, 0S
TV: 32B, 75C, 45S, 50H, 5S
HDTV: 37B, 95C, 43S, 60H, 5S
(The backlight lamp is set to 0 for all the above.)
Trouble is, they depend on the specific conditions associated with my viewing.
Example: My HDMI connection is fed with a 20ft Blue Jeans HDMI cable from an LG DVB418 player. If you don't have the exact same configuration then you are likely to need different values. This also depends on the amount of light in your room, your evaluation of the amount of push offset required in the saturation setting, and the maximum white you are looking for. Plus, there is no guarantee one optimal set of values for a given configuration will be equally optimal on a different example of the same model. (Your distance from the set could also inspire some adjustments.)
A second example: My YPbPr1 connection is fed with 16ft Blue Jeans component cables from a Pioneer DV-414 player. You can expect your optimal adjustments to vary accordingly
Further, my TV and HDTV settings are dependent on my cable hookup and provider, and there is no reason at all to presume they conform to some nationwide standard (which probably doesn't exist).
The most likely possibility for color improvement via the Service Panel is a reduction of push -- typically red due to overly enhanced blue levels. This is something I have always been able to work around to my personal satisfaction, but is certainly a valid concern -- that is something an ISF technician would be happy to adjust (among other items) if you greased their palms with the appropriate number of dollars
. Optimizing the color temperature is also a biggie.
My approach is to use VE to get the best values for brightness, hue, saturation, and sharpness that I can (plus a starting point for contrast), and then further adjust the saturation and contrast to give me the best balanced picture I can manage from top flight material. In other words, for me it is both objective in the application of VE, plus subjective in the application of my personal expectations.
However, without having a reliable starting point (VE in my case) it is very difficult to produce an optimal picture, though to be sure, one can potentially arrive at a pretty good one.
An additional problem is both video anomalies and color impurities due to power issues, the only resolution for which is a decent power conditioner -- I can't over-emphasize that. The same is true for every other device in your A/V chain.

EDIT: I've since had to re-evaluate the saturation and hue settings with HDMI due to having identified a definite Green Push -- that's new for me and I didn't recognize it during calibration. The manufacturer intended effect is apparently to make grass look especially green for sports events -- great for watching football I guess (both American and the rest of the world). I've had to push the hue up to 70 to correct it's effect and raise the saturation to 52 to balance. This seems to fix the problem, but now I have to live with it for awhile -- to be sure it doesn't create other problems.
