I must've read Ninguemrj's question the same as d0a0b, in the normal onscreen menu, there are a series of color temps but they don't specify C or F.
Therefore when Hans responded back with just Celsius, it made perfect sense.
2) And what the color temperature stands for? Is it an information about the led chip temperature in Celsius or Fahrenheit?
Also, seeing as how the question was worded, it certainly doesn't appear that Ninguemrj was asking about the actual "Color Temperature" in Kelvin.
I've verified the CRE-X1000PX model also has the "service" menus (simply pushing the 1, 2, 3, 4, sequentially once each brought it up for me), here's a few pics of the service menus and me adjusting the R down to 30 and again up to 255 and at at the default 128, and then the R offset down to 0, up to 255, and back to 128. I've also changed the color tone settings and then went back to this setting, to see what changes occurred at the different color tone settings http://www.flickr.com/photos/7926221...7629537354674/
it certainly seems to me like this may be some of that CMS some of you were requesting.
As for the "non-linear" sections, such as brightness levels 0-4, contrast, saturation, sharpness, and volume settings, it appears to me (and I could be wrong) to be a ladder stepping that doesn't effect the screen directly but rather it allows you to set the low, medium low, medium, medium high and high settings for each of these "steps".
For those who venture forth to change these settings, obviously you do so at your own risk. In the normal menu under the "system" tab there is a setting to recall memory, but i do not know if it will revert all settings or only those listed in the basic menu. Worth a try though if you get in over your head.
I forgot to mention, there also are a few handy test patterns in the service menu, White, Red, Green, Blue, Cyan, Magenta, Black, and Crosshatch
