2. Picture check
1) WHITE-D adjustment
General set-up :
Equipment Requirements: Minolta CA-210 or Equivalent Color analyzer Chroma 2250 or equivalent PC signal generator
input requirements:
Input Signal Type : PC VGA signal
1280 X 1024/60Hz PC mode with ”5 white block” pattern. (see pattern-1)
Input Signal Strength : 0.7 Vp-p linear voltage.
Input Injection Point : PC D-SUB input
Pattern-1
Alignment method:
Initial Set-up:
1>. Select source as “PC”.
2>. Set Contrast = 50 (Sharp) and Brightness=50 (Sharp) , at normal menu mode.
3>. Apply “5 white block”(pattern-1) pattern by VGA pattern generator.
4>. Enter factory mode menu: press MENU + Numeric keys “062596” + MENU 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 Flat80 pattern (80% white pattern).
3>. Set color temperature to “NORMAL”.
4>. At FAC mode menu, adjust the CLR TEMP R, CLR TEMP G, CLR TEMP B values to meet “NORMAL” color coordinates specification below. Then
store those values to NVM
5>. Set color temperature to “COOL”.
6>. At FAC mode menu, adjust the CLR TEMP R, CLR TEMP G, CLR TEMP B values to meet “COOL” color coordinates specification below. Then store
those values to NVM
7>. Set color temperature to “WARM”.
8>. At FAC mode menu, adjust the CLR TEMP R, CLR TEMP G, CLR TEMP B values to meet “WARM” color coordinates specification below. Then store
those values to NVM

Table 5: Reading with Minolta CA-210.
Note:
1>. Use Minolta CA-210 for color coordinates and luminance check.
2>. Befor adjusting,all colour analyzers (CA-210) should be coordinates with a same reference TV set.
3>. Luminance > 400 cd/m
