White Balance Adjustment
For white balance adjustment, adjust the offset values on pages 11/21.
[Condition of the unit for inspection] : Modulated light (+16), Colour temperature (High)
AV MODE: DYNAMIC
Active Backlight: OFF
OPC: OFF
Asing Time: Min,60 minute
[Input signal condition] : HDMI 1080i 15IRE (LO), 78IRE (HI)

[Adjustment procedure]
1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 11/21 of process adjustment)
The signal of 78IRE is input.
2) Read the value of the luminance meter. x = 0.272, y = 0.277
3) Change R_GAIN (HI)/B_GAIN (HI) (Adjustment offset value) on page 11/21 of process adjustment so that the values of the luminance meter
approach x = 0.272 and y = 0.277.
(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R or B must be fixed.)
4) Display the adjustment status of the current R/G/B_GAIN (LO).
The signal of 15IRE is input.
Change R_GAIN (LO)/B_GAIN (LO) (adjustment offset value) on page 11/21 of process adjustment so that the values of the luminance meter
approach x = 0.272 and y = 0.277.
5) Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.
[Adjustment reference standard value]
Adjustment spec ± 0.002 Inspection spec ± 0.004 (point LO)
Adjustment spec ± 0.001 Inspection spec ± 0.002 (point HI)
