Video W/B Adjustment; W/B High Mode Adjustment; W/B Low Mode Adjustment - Sony VPL-FX51 Service Manual

2-6. VIDEO W/B Adjustment

2-6-1. W/B HIGH Mode Adjustment

1. Input the 15KHz Component Flat Field signal to the
INPUT-A. Then, select COMPONENT from INPUT-
A of the SET SETTING.
2. Set D.PICTURE of PICTURE CONTROL to "OFF".
3. Set 06 3D GAMMA/THROUGH to 0 (LUT ON).
4. Set 07 3D GAMMA/SW to 1 (3Dγ ON).
5. Enter the menu item WB ADJUST HIGH.
6. After making sure of data R/G/B BIAS and GAIN
adjusted in advance, duplicate them to GAIN and
BIAS applied to the W/B LOW Mode Adjustments.
7. Input the 15 KHz Component Flat Field 80 IRE signal
to the INPUT-A.
8. Adjust the y value in the W/B HIGH G Gain. When
the X value inclusive of y value is bigger than the
specified, regard Blue as the referenced color.
To the contrary, when smaller, regard Red as the
referenced. Chromaticity is to be adjusted to satisfy
with the follows in the GAIN other than such refer-
enced colors.
9. Input the Component flat field 30 IRE signal to the
INPUT-A.
10. On the BIAS other than the referenced color, adjust the
y value to get the following chromaticity.
11. Perform tracking adjustment so that both 80 IRE and
30 IRE can satisfy the standard value.
12. Select the item "SAVE TO MEMORY" of W/B
ADJUST of the menu. Press ENTER to save data.
HIGH MODE Chromaticity Spec. :
(x, y) = (0.275, 0.312) ± 0.005 (80 IRE)
HIGH MODE Chromaticity Spec. :
(x, y) = (0.275, 0.312) ± 0.007 (30 IRE)

2-6-2. W/B LOW Mode Adjustment

1. Enter the menu item WB ADJUST LOW.
2. Make sure first that data of section 2-6-1.6 is already
been written in the R/G/B GAIN. BIAS.
3. Input the Component Flat Field 80 IRE signal to the
INPUT-A.
4. Adjust the y value in the W/B HIGH G Gain. When X
value inclusive of y value is bigger than the specific
value, regard Blue as the referenced color.
To the contrary, when smaller, regard Red as the
referenced. Chromaticity is to be adjusted to satisfy
with the follows in the GAIN other than such refer-
enced colors.
5. Input the 15KHz Component Flat Field 30 IRE signal
to the INPUT-A.
6. On the BIAS other than the referenced color, adjust the
y value to get the following chromaticity below.
7. Perform tracking adjustment so that both 80 IRE and
30 IRE can be within the standard value.
8. Select the item "SAVE TO MEMORY" of W/B
ADJUST of the menu. Press ENTER to save data.
9. Set D.PICTURE of PICTURE CONTROL to "ON".
LOW MODE Chromaticity Spec. :
(x, y) = (0.310, 0.340) ± 0.005 (80 IRE)
LOW MODE Chromaticity Spec. :
(x, y) = (0.310, 0.340) ± 0.007 (30 IRE)
