6.1 General Alignment Conditions
6.2 CVI (YPbPr) source Auto Colour Adjust
6.3 White Balance Adjustment
6.4 Serial Number Definition
Note: The Service Alignment Mode (SAM) are described in
chapter 5. Service Modes, Error Codes, and Fault
Menu navigation is done with the CURSOR UP, DOWN, LEFT
or RIGHT keys of the remote control transmitter.
6.1 General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage: 220 - 240 V
• Connect the set to the mains via an isolation transformer
with low internal resistance.
• Allow the set to warm up for approximately 15 minutes.
• Measure voltages and waveforms in relation to correct
ground.
Caution: It is not allowed to use heatsinks as ground.
• Test probe: Ri > 10 MΩ, Ci < 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 CVI (YPbPr) source Auto Colour Adjust
6.2.1 Equipment Requirements
Quantum Data Pattern Generator 802G or 802R or 882. Apply
576i, and the pattern TVBAR100 shown as below.

6.2.2 Alignment method
1. Select source as "YPbPr".
2. Set Smart picture as "Personal" and adjust Brightness to
50, Contrast to 50, and Colour to 50.
3. Access to factory OSD first, then to enable AUTO-COLOR
to get HD ADC OFFSET and HD ADC GAIN. Check 32
Gray scales can be distinguishable.
6.2.3 Process
1. Press "MENU" key.
2. Press digit "1999" to enter factory mode.
3. Press UP/DOWN to move curser to "AUTO COLOR".
4. Press RIGHT to do "ADC GAIN" and "ADC OFFSET".
5. Choose "EXIT" and press "OK".

6.3 White Balance Adjustment
6.3.1 Equipment Requirements
Color analyzer.
6.3.2 Input requirements
For SZ factory:
• Signal Type: RF signal
1. Set to PAL D/K system, frequency=184.25MHz ( for
China model ) with white pattern of 100%.
2. Set to PAL B/G system, frequency=64.25MHz ( for AP
model ) with white pattern of 100%.
• Input Signal Strength: 10mV (80 dBuV) terminal voltage.
• Input Injection Point: TV Tuner input.
For FQ factory:
• Signal Type: CVI (YPbPr)
1. Using Quantum Data Pattern Generator 802G or 802R
or 882.
2. Set to 576i with white pattern of 100% (flat patten).
6.3.3 Alignment Request in the center of the screen
1. Apply full white pattern, select smart setting to be
"PERSONAL".
2. Adjust Brightness = 50, Contrast = 50, and Color = 50.
3. Adjusting SCALER GAIN R G B to reach W/D and
luminance in factory mode as below.
4. Enter factory mode menu: press numeric keys "MENU" +
"1999" key (FAC mode menu).
5. Adjust Color Temp in the factory Mode OSD by adjusting
GAIN R xxx G xxx B xxx in factory

y (center) 0.278±0.015
Notes:
• R/G/B Gain value <= 124 to avoid satsuation at 32-grey
pattern.
• At TV Luminance at Normal >= 400cd/m2 when contrast
and brightness and color are 100%.
• These group settings about color temp are also applied
automatically into HDMI1/CVI(for SZ factory)/SIDE
AV/TV(for FQ factory). That means TV/HDMI/CVI use the
same setting.
