2. Picture check
1) WHITE-D adjustment
General set-up :
Equipment Requirements: Minolta CA-110 or Equivalent Color analyzer Chroma 2250 or equivalent PC signal generator input requirements:
Input Signal Type : PC VGA signal
1024X768/60Hz 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 (CMO) and Brightness=50 (CMO) , at normal menu mode.
3. Apply “5 white block”(pattern-1) pattern by VGA pattern generator.
4. Enter factory mode menu: Numeric keys “062596” + “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 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
3. Set color temperature to “COOL”.
4. 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
3. Set color temperature to “WARM”.
4. 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
