[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 exceeds the initial value (input gradation x 4), round off it to that
value or less.
3) Set the point 5 to the specified gradation, and set the G correction value (792 x G
value of point 6/928) (fractions rounded off) and the Ye correction value (792 x Ye
value of point 6/928) (fractions rounded off); then adjust RB so that it becomes the
standard value.
4) Set the point 4 to the specified gradation, and set the G correction value (608 x G
value of point 6/928) (fractions rounded off) and the Ye correction value (608 x Ye
value of point 6/928) (fractions rounded off); then adjust RB so that it becomes the
standard value.
5) Set the point 3 to the specified gradation, and set the G correction value (348 x G
value of point 6/928) (fractions rounded off) and the Ye correction value (348 x Ye
value of point 6/928) (fractions rounded off); then adjust RB so that it becomes the
standard value.
6) Set the point 2 to the specified gradation, and set the G correction value (264 x G
value of point 6/928) (fractions rounded off) and the Ye correction value (264 x Ye
value of point 6/928) (fractions rounded off); then adjust RB so that it becomes the
standard value.
7) Set the point 1 to the specified gradation, and set the G correction value (180 x G
value of point 6/928) (fractions rounded off) and the Ye correction value (180 x Ye
value of point 6/928) (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 928
* RGB initial value of points 1 to 5: G correction value of each point
(At each point, make adjustment so that the remainder of the RGB adjustment value/4 is
equal.)
[Adjustment value]
* According to the “Standard settings” submitted by the Technical Department
[LC80LE844U] teaching set
Teaching must be made with the unevenness cancellation off.
