For white balance adjustment, adjust the offset values on pages 11/21.

[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)

[Adjustment reference device]         : Minolta CA-210

[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)

6) After completing adjustments, set EEP SAVE (Page 21/21) to ON in the process menu to save the white balance adjustment value.
