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: 195 - 264 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: R > 10 MΩ, C
i
• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 Hardware Alignments

6.3 YPbPr Mode display adjustment
6.3.1 General set-up
Equipment Requirements:
Minolta CS-200 or equivalent Colour analyser, Quantum Data
Pattern Generator 802G, 802BT or equivalent instrument.
Input requirements:
Input Signal Type: YPbPr signal
• 1080i mode, TVBar100 pattern by 802G or 802BT.
• Select Picture mode to User mode and check the x, y data.
Input Signal Strength:
1 V for Y signal; 700 mV
pp
Input Injection Point:
YPbPr (RAC jack)
6.3.2 Alignment method
Quantum Data Pattern Generator 802G or 802BT. Apply 1080i,
and the pattern TVBAR100 with a Quantum colour analyser.
Initial Set-up:
1. Select source as "EXT2".
2. Set Smart Picture mode as "Standard" and off the
"Dynamic contrast/Dynamic backlight".
3. Apply "TVBar100" pattern with colour bar pattern by signal
generator.
4. Enter factory mode menu: press numeric keys
"062596" + INFO key (FAC mode menu).

Alignment:
1. At SAM 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 100% white pattern.
3. Set colour temperature to "NORMAL".
4. At FAC mode menu, adjust the CLR TEMP R, CLR TEMP
G, CLR TEMP B values to meet "NORMAL" colour
coordinates specification below. Then store those values to
NVM (R/G/B gain value <= 128).
5. Set colour temperature to "COOL".
6. At FAC mode menu, adjust the CLR TEMP R, CLR TEMP
G, CLR TEMP B values to meet "COOL" colour
coordinates specification below. Then store those values to
NVM (R/G/B gain value <= 128).
7. Set colour temperature to "WARM".
8. At FAC mode menu, adjust the CLR TEMP R, CLR TEMP
G, CLR TEMP B values to meet "WARM" colour
coordinates specification below. Then store those values to
NVM (R/G/B gain value <= 128).

• Check Luminance:
Use Minolta CS-200 or Equivalent Colour analyser for
colour coordinates and luminance check. Then Set CS-200
