2-12. White Balance Adjustment
2-12-1. Sub Bright Adjustment
1 Receive Gray Scale pattern signal.
* Gray scale : 0, 5, 10, 15 IRE (4 Steps)
2. Set the following items at PICT/SOUND CTRL.
CONTRAST 8 MIN
BRIGHTNESS 8 0 (CENTER)
3. Adjust SUB BRIGHT using the resistor of [SUB
BRIGHT] at SEVICE MODE [SIGNAL] - [WHITE
BALANCE].
Check 0 and 5 IRE section of Gray Scale is completely
cut off and 10 IRE section of it lights faintly. (If not
readjust it.)
2-12-2. White Balance Adjustment [D65]
1. Set the COLOR TEMP to D65.
2. Receive window pattern signal.
3. Adjust the D65 white balance within standard (de-
scription below) using the resistor [R DRIVE] and [B
DRIVE] at SERVICE MODE [SIGNAL]-[WHITE
BALANCE]-[AJUST GAIN].
XY
D65 313 329
Switch the item R 8 G 8 B with [ENTER], and
change the data with [+]/[_].
4. Change over to all white signal and lower signal level ,
set brightness to 3 (+1/_0) cd/m
2
.
5. Adjust the D65 white balance within standard (de-
scription below) using the resistor [OFFSET R] and
[OFFSET G] at SERVICE MODE [SIGNAL]-
[WHITE BALANCE]-[AJUST BIAS].
XY
D65 313 329
Switch the item R 8 G with [ENTER], and change
the data with [+]/[_].
6. Repeat the manual 2 to 5 until be able to adjust GAIN
side and BIAS side to the same value.
2-12-3. White Balance Adjustment [D93]
1. Receive window pattern signal.
2. Set the COLOR TEMP to D93.
3. Adjust the D93 white balance within standard (de-
scription below) using the resistor [R DRIVE] and [B
DRIVE] at SERVICE MODE [SIGNAL]-[WHITE
BALANCE]-[AJUST GAIN] .
XY
D93 283 298
Switch the item R 8 G 8 B with [ENTER], and
change the data with [+]/[_].
4. Change over to all white signal and lower signal level,
set brightness to 3cd/m
2
.
5. Adjust the D65 white balance within standard (de-
scription below) using the resistor [OFFSET R] and
[OFFSET G] at SERVICE MODE [SIGNAL]-
[WHITE BALANCE]-[AJUST BIAS] .
XY
D93 283 298
Switch the item R 8 G with [ENTER], and change
the data with [+]/[_].
6. Repeat the manual 2 to 5 until be able to adjust GAIN
side and BIAS side to the same value.
