in the center of the screen when Brightness control at 100; Contrast control at 100 for CMO 26”, 32”, 42” panels.

White balance adjustment
General set-up :
Equipment Requirement: Minolta CA-110 or Equivalent Color analyzer
Quantum Data Pattern Generator 802G , 802BT or equivalent instrument
Input requirements:
Input Signal Type : YPbPr signal
1. 720P mode, TVBar100 pattern by 802G or 802BT.
2. Select Smart picture to Personal mode and check the x, y data.
Input Signal Strength : 1 Vpp for Y signal ; 700 mVpp for Pb & Pr signal
Input Injection Point : AV1 YPbPr (RAC jack)
720P, TVBar100 pattern
Alignment method:
Initial Set-up:
1. Select source as “AV1”.
2. Set Smart picture as “Personal” and to be Contrast =50,
Brightness=50 , at normal menu mode.
3. Apply “TVBar100” pattern (with black & white bar )by signal generator.
4. Enter factory mode menu: press Numeric keys “062596” then perss Display key (FAC mode menu). Then select “Factory”
item.
Alignment:
1. At FAC mode menu, select AUTO_COLOR item. Then press “OK” key to adjust ADC_GAIN_R, ADC_GAIN_G,
ADC_GAIN_B and ADC_OFFSET_R, ADC_OFFSET_G, ADC_OFFSET_B. Then store those values to NVM.
2. Apply Flat_73 pattern or 75IRE pattern.
3. Set color temperature to “NORMAL”.
3. Copy CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values from “NORMAL” color temperature in Analog TV mode.
Check whether (x,y) color coordinates meet “NORMAL” color specification below. If color coordinates are out of
specification, fine-tune CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values. Then store those values to NVM. ( R/G/B
gain value <= 130 )
4. Set color temperature to “WARM”.
5. Copy CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values from “WARM” color temperature in Analog TV mode.
Check whether (x,y) color coordinates meet “WARM” color specification below. If color coordinates are out of specification,
fine-tune CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values. Then store those values to NVM. ( R/G/B gain value
<= 130 )
6. Set color temperature to “COOL”.
7. Copy CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values from “COOL” color temperature in Analog TV mode. Check
whether (x,y) color coordinates meet “COOL” color specification below. If color coordinates are out of specification, fine-tune
CLR_TEMP_R, CLR_TEMP_G and CLR_TEMP_B values. Then store those values to NVM. ( R/G/B gain value <= 130 )
