Be advised that neither my settings, nor anyone else's settings, are necessarily the best for you, for the following reasons:
1. Differences between personal preferences.
2. Differences in lighting conditions
3. Differences from one set to another (especially lamps--yes, a new lamp should mean a new ISF calibration)
4. Differerences between broadcasters, networks, cable companies and satellite services.
5. Differences between set top boxes and between DVD players.
In subsequent posts, I and others provide the original factory settings for the red, green and blue gain parameters in the service menu. Based on the degree of difference observed between the factory settings for RGB gain, it is obvious that the sets vary from each other more than a little (hence requiring substantially different RGB gan parameter values.)Unfortunately, the optimal settings for brightness, contrast and color intensity depend in no small measure on both the color temperature and the grayscale (both of which are controlled by the RGB gain and RGB bias settings in the service menu.)
The inescapable conclusion is that the best user-level settings for one set may differ than those for another, unless both sets have the same grayscale and color temperature.
Absent a professional calibration, the only workable option is to use the same RGB gain settings on all sets that will share the same user-level settings. Although that is far from perfect, as long as the RGB gain values are correct for the set on which they were originally derived, and also happen to be close to the values that are on-average correct for all the sets of the same make and model, it often produces a pretty good result that should at least be acceptable until a professional ISF calibration can be performed (but often does not mean always--and you may not be one of the lucky ones.)Bottom line
: One person's settings should be seen as a starting point that helps others more quickly arrive at settings that work best for them.Sourcery's WD-xx831 Settings
The user-level settings I provide below are optimized for my personal preferences and lighting conditions, and for the characteristics of my set's electronics, light engine and lamp. They are also optimized for my current RGB gain parameter values (as set in the service menu, and mostly as recommended by forum member jjnelson2000
and listed below.) In other words, the optimal settings for your set and for your viewing conditions will probably be different, but may not be too far different than the ones below. I provide my preferred settings on the theory that, on average, the typical variation between sets, viewing conditions and viewing preferences are not all that great. But that assumption doesn't always hold.
Update: My set developed the infamous halo ("blooming") problem. For now, that has been fixed by replacing the original light engine with a new one. There are two interesting facts about the new light engine: 1) The set looks better than it ever did, with absolutely inky blacks; and 2) I had to lower the contrast and raise the brightness (and the brightness had to be raised higher than would have ever been good with the original light engine.) The moral of this story should be obvious: There is non-trivial variation between sets of the same year, make and model as to which settings are optimal. The settings offered here may need to be tweaked to get you the best picture on your particular set.Picture Mode
[The "picture mode" sets the auto-iris, and I believe it may also change the contrast and/or gamma. The three modes are Natural, Bright and Brilliant. Contrast, brightness and color temperature must be set independently for each picture mode, all other settings are shared among the three picture modes]Color Temperature

I use Digital Video Essentials to set brightness, contrast and sharpness.
In the absence of the requisite equipment, I use my own judgement to set color and hue. The DVE color/hue setting procedure apparently depends upon an accurate grayscale/color temperature, which my set does not yet have.
My goals in tweaking the picture settings are as follows:
1. Make the picture look as real and natural as possible. I look at the real world, observe how things really look, and try to make the picture on the TV look like that.
2. Blacks should be black, but details of the picture should not be obscured. The sense of depth should be maximized.
3. Minimize artifacts, pixelation, macroblocking, ringing, noise, white crush and black crush.Pictures

:The Service Menu
Service menu settings are universal across all inputs.WARNING: Write down all defaults if you are going to change anything. Do not change anything you don't understand. Changing some of the settings may permanently damage your TV, or make it impossible to see any picture at all (so that no one would ever be able to see what was happening on the screen so that they could fix the problem using the service menu.)
According to UMR (Jeff Meier,) who is a professional ISF calibrator, "...in the past if you happened to press PIP while in the SM the memory was hosed and would need to be reset by a factory download. Who knows what little gems are present in this model that can cause your display to go south."
To enter the service menu, press the following keys in sequence on the remote: MENU 2 4 5 7
To see the video test patterns: fast forward, rewind
To scroll through the options, press the VIDEO key.
To change the values, press the UP or DOWN buttons.
To save a change, press the ENTER button.
To exit without saving, just press the EXIT button.
