Below white balance adjustment takes 42” model as an example. For other models, use the
above data as a reference for alignment.
3.2.2 White balance data alignment at four modes
a) Alignment at ATV mode (AV and S-VIDEO is the same)
In TV mode, set Air/Cable to Air. Input test signal with 11 gray steps. From Factory menu select
“Color Temp” item and set it to “COOL”, fix GAIN GREEN, adjust GAIN RED and GAIN BLUE to
make 9
th
step color coordinate to be (272, 278). Fix OFFSET GREEN, adjust OFFSET RED and
OFFSET BLUE to make the third step color coordinate to be (272,278). In this way repeatedly
adjust GAIN RED, GAIN BLUE and OFFSET RED, OFFSET BLUE until two level gray step’s
color coordinate be (272,278). Then select “MENU” to return to previous menu or select “SAVE
TO EEPROM” to save the white balance.
Check if NORMAL and WARM color temperature meet the requirement. If not, then adjust GAIN
RED, GAIN BLUE, OFFSET RED, OFFSET BLUE to make them meet requirements, and then
save.
b) Alignment at DTV mode (HDMI is the same)
In TV mode, set Air/Cable to Air. Input test signal with 11 gray steps. From Factory menu select
“Color Temp” item and set it to “COOL”, fix GAIN GREEN, adjust GAIN RED and GAIN BLUE to
make 9
th
step color coordinate to be (272, 278). Fix OFFSET GREEN, adjust OFFSET RED and
OFFSET BLUE to make the third step color coordinate to be (272,278). In this way repeatedly
adjust GAIN RED, GAIN BLUE and OFFSET RED, OFFSET BLUE until two level gray step’s
color coordinate be (272,278). Then select “MENU” to return to previous menu or select “SAVE
TO EEPROM” to save the white balance.
Check if NORMAL and WARM color temperature meet the requirement. If not, then adjust GAIN
RED, GAIN BLUE, OFFSET RED, OFFSET BLUE to make them meet requirements, and then
save.
c) Alignment at YPbPr mode
First do ADC correction: input 75% color bar plus gray step signal in 480i/60Hz format, (VG848
Timing is 968, PAT is 918), enter Factory Menu select ADC Setting, do ADC AUTO adjustment
once.
