If I select "custom" so that advanced setting and white balance adjustments are enabled (for example, using the CNET settings listed in post #17), I don't find that the RGB gain and/or RGB bias adjustments do anything.
I find the blues tend too much toward the purple side of the scale (from the CNET settings), but even if I max the gain and the bias (I tried all 3 of the R, G, and B with no difference) it doesn't visibly change the blue at all.
The gain is negative so I guess it's actually attenuation (zero is the default and changes are in the negative direction), so I would think that a more negative gain setting on Red and Green would make the Blue go more towards a pure blue but it doesn't seem to do anything. Is there some other setting I need to change before the white balance adjustments have an effect?
About all I seem to be able to control for blues is darkness or brightness, but nothing via the white balance control.
I noticed this as well, In Picture->Advanced Settings 'White Balance' and 'Clear White' did nothing noticeable. After poking around in the hidden menu's I have fixed it. Now they work as they should.Here's how to fix it
Enter the Factory menu:
- Turn TV on
- On remote press: Left Arrow, Right Arrow, Mute, Select (center button), Mute, Menu (home)
(all buttons must be pressed within 1s of each other)
- Select "white balance" and set it to on.
Should work now. Re-entering the factory menu shows it as off again but that doesn't seem to matter, 'White Balance'&'Clear White' still work.
By the way, if anyone is interested, finer color calibration is available in the factory menu under 'Color Temp' and 'ADC calibration' (ADC seems only available under PC or component inputs). If anyone knows what 'Aging Mode' means I'm curious to know. I may have accidentally switched it on.
