For each color there are 3 individual controls for what I'm assuming is gain, saturation, and hue. You'll want to use these settings to help bring the colors in to the reference levels.
GL - The gain control will control the luminance (or Y) value of the selected color. This doesn't change the x,y coordinates much but will have a definate impact on the luminance. The corresponding PerfectColor seems to control the same thing this service menu control does, but at a larger granularity and with a different range. This is the control that affects the brightness of a given color.
SL - This controls the saturation, or amount of color at any given brightness. As you drop this control to 0, the color will shift toward a shade of grey at a similar brightness. If you are looking at the colors on the CIE94 plot, this controls effect will seem to move the colors coordinates inward toward the white point.
HL - on the CIE94 plot the hue control will adjust the angle of the color from white. For those with PerfectTint controls, this is probably similar to adjusting that.
If you imagine there being a circle placed with it's center at the white point, the hue will adjust the color along the circumference of the circle, while saturation will adjust the radius.
I'm not an expert or professional calibrator so YMMV, but after entering and exiting the service menu many many times (and this is quite tedious!) in the process of my calibration this is how I saw the x,y points behaving after changing the service menu controls.

Madsend,
Good explanation - makes things clearer to me. Also good tips on how to use each control.
Have only used saturation and hue in service menu with pretty poor results.
Haven't used Gain in service menu at all. Also haven't used 'perfect tint' but will try tomorrow.
















. Once again, I was able to get everything "perfect" with the BLUE and RED filters, but with the GREEN filter, nothing except CYAN would line up. This time around, skin tones look much better, but WHITES are "dirty" and too warm and the overall picture, especially on the satellite is too warm and looks "dirty". I toggle back and forth with HIGH and LOW color temp settings and going back to HIGH improves the overall look and brings whites closer back to white, but then skin tones go to hell again at times. Again, the demo material on the disk looke pretty good, but when playing movies and sattellite, it doesn't.
