8.1 Electrical Instructions
8.1.1 EXT3 YPbPr Mode Display Adjustment
Requirements
Equipment requirements:
- Minolta CA-110 or CA-210 or equivalent colour analyser.
- Quantum Data pattern generator 802G, 802BT, 881 or
equivalent instrument.
Input requirements:
Input signal type: YPbPr signal
1.
1080i mode, TVBar100 pattern by 802G or 802BT or 881.
2. Set “Smart Picture” to “Personal” mode and check the
x, y data.

Pb & Pr signal.
Input Injection Point: EXT3 YPbPr (RAC jack) 1080i, TVBar100
pattern.
Figure 8-1 Pattern 27
Alignment method:
1. Select source as "EXT3".
2. Set Smart picture as "Personal" and Contrast=50,
Brightness=50, Color=50.
3. Apply "SMPTE color" pattern or "color bar with black &
white" pattern by signal generator.
4. Enter factory mode menu: press numeric keys "062596" +
"INFO" key+ "MENU" key (FAC mode menu). Then select
"Factory" item.
Alignment
1. In “FACTORY” mode menu, select AUTO_COLOR item.
Then press the "OK" key to auto 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 full white pattern.
3. Set “Color Temperature” to "NORMAL".
4. In “FACTORY” mode menu, keep the CLR_TEMP_B=128,
and adjust the CLR_TEMP_G, CLR_TEMP_R values to
meet the "NORMAL" colour coordinates as specified
below. Then “STORE” those values to NVM.
5. Set “Color Temperature” to "WARM".
6. In “FACTORY” mode menu, keep the CLR_TEMP_R=128,
and adjust the CLR_TEMP_G, CLR_TEMP_B values to
meet the "WARM" colour coordinates specified below.
Then “STORE” those values to NVM.
7. Set “Color Temperature” to "COOL".
8. In “FACTORY” mode menu, keep the CLR_TEMP_B=128,
and adjust the CLR_TEMP_G, CLR_TEMP_R values to
meet the "COOL" colour coordinates specified below. Then
“STORE” those values to NVM.
Output detection point: screen center.

Input requirements:
Input Signal Type: PC VGA signal
1.
1024x768@60Hz PC mode with 5 white block pattern.
(see the next figures)
2. Select “Colour Temperature” to “Normal”, and check the
x, y data.
Input signal strength: 0.7 Vpp linear voltage.
Input injection point: PC D-SUB input.
Settings
1. Select source as "PC".
2. Set Contrast= 50, Brightness= 50, set “Color Temperature”
as “Normal” and set “Picture Format” as “Full Screen”.
3. Apply "5 white block" pattern by VGA generator.
Alignment:
1. In “FACTORY” mode menu, select AUTO_COLOR item.
Then press the "OK" key to auto 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. Set “Color Temperature” to "NORMAL".
3. In “FACTORY” mode menu, keep the CLR_TEMP_B=128,
and adjust the CLR_TEMP_G, CLR_TEMP_R values to
meet "NORMAL" color coordinates specification above.
Then “STORE” those values to NVM.
4. Set “Color Temperature” to "WARM".
5. In “FACTORY” mode menu, keep the CLR_TEMP_R=128,
and adjust the CLR_TEMP_G, CLR_TEMP_B values to
meet "WARM" color coordinates specification above. Then
“STORE” those values to NVM.
6. Set “Color Temperature” to "COOL".
7. In “FACTORY” mode menu, keep the CLR_TEMP_B=128,
and adjust the CLR_TEMP_G, CLR_TEMP_R values to
meet "COOL" color coordinates specification above. Then
“STORE” those values to NVM.
Check gray scale
Check the color poor & noise condition of a 32 gray scale
pattern.
