Point 3
1) Set the unit to the following conditions.
AV MODE: [DYNAMIC]
Backlight: +16
Active Backlight: OFF
Aging Time: Min. 60 minutes
2) Connect the unit with the white balance adjustment jig.
[Adjustment procedure]
1) Send the "adjustment process" code using the remote control.
2) Set the point 6 to the specified gradation, specify the strongest color as the fixed
color, and adjust the RGB so that it becomes the standard value through negative
adjustment.
After adjustment, compare the R and G values; based on that result, calculate the Ye
value in the following conditions.
R > G: Ye = G x 1.05
R G: Ye = R x 1.05
* If the Ye value exceed the initial value (input gradation x 4), round off it to that value
or less.
3) Set the point 5 to the specified gradation, set the G correction value (692 x G value of
point 6/916) (fractions rounded off) and the Ye correction value (692 x Ye value of
point 6/916) (fractions rounded off) then adjust RB so that it becomes the standard
value.
4) Set the point 4 to the specified gradation, set the G correction value (532 x G value of
point 6/916) (fractions rounded off) and the Ye correction value (532 x Ye value of
point 6/916) (fractions rounded off) then adjust RB so that it becomes the standard
value.
5) Set the point 3 to the specified gradation, set the G correction value (464 x G value of
point 6/916) (fractions rounded off) and the Ye correction value (464 x Ye value of
point 6/916) (fractions rounded off) then adjust RB so that it becomes the standard
value.
6) Set the point 2 to the specified gradation, set the G correction value (296 x G value of
point 6/916) (fractions rounded off) and the Ye correction value (296 x Ye value of
point 6/916) (fractions rounded off) then adjust RB so that it becomes the standard
value.
7) Set the point 1 to the specified gradation, set the G correction value (180 x G value of
point 6/916) (fractions rounded off) and the Ye correction value (180 x Ye value of
point 6/916) (fractions rounded off) then adjust RB so that it becomes the standard
value.
8) Write the adjustment value by the MSET0003 command and turn off the AC power.
* RGB initial value of point 6: Set gradation 916
* RGB initial value of points 1 to 5: G correction value of each point
