For white balance adjustment, adjust the offset values on pages 11/20.
[Condition of the unit for inspection] : Modulated light (+16)
AV MODE: DYNAMIC
Active Backlight: OFF
OPC: OFF
Asing Time: Min, 60 minute
[Input signal condition] : HDMI 1080i 15IRE (LO), 78IRE (HI)

Asing Time: Min, 60 minute
[Input signal condition] : HDMI 1080i 15IRE (LO), 78IRE (HI)
[Adjustment reference device] : Minolta CA-210
[Adjustment procedure]
1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 11/20 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 11/20 of process adjustment so that the values of the luminance meter
3) Change R_GAIN (HI)/ B_GAIN (HI) (Adjustment offset value) on page 11/20 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.)
(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 11/20 of process adjustment so that the values of the luminance meter
Change R_GAIN (LO)/ B_GAIN (LO) (adjustment offset value) on page 11/20 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)
Adjustment spec ? 0.002 Inspection spec ? 0.004 (point LO)
Adjustment spec ? 0.001 Inspection spec ? 0.002 (point HI)
6) After completing adjustments, set EEP SAVE (Page 20/20) to ON in the process menu to save the white balance adjustment value.
