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
AC
, 50/ 60 ± 3 Hz.
• 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
i
> 10 MΩ, C
i
< 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.

6.3 YPbPr Mode display adjustment
6.3.1 General set-up
Equipment Requirements:
Minolta CA-110 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
pp
for Y signal; 700 mV
pp
for Pb & Pr signal
Input Injection Point:
YPbPr (RAC jack)
6.3.2 Alignment method
Quantum Data Pattern Generator 802G or 802BT. Apply 1080i,
and the pattern TVBAR100 shown as below.
Initial Set-up:
1. Select source as “EXT3”.
2. Set Smart Picture mode as “Vivid” 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 80% 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).
Colour temperature Normal/Warm/Cool (x, y) co-ordinates
specification:
Table 6-1 Reading with Minolta CA-210
If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production.
• Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).
• Set the RED, GREEN and BLUE default values according
to the values in Table 6-2
• When finished press OK on the RC, then press STORE (in
the SAM root menu) to store the aligned values to the NVM.
• Restore the initial picture settings after the alignments.

Caution:
• Use Minolta CA-210 for colour coordinates and luminance
check.
• Luminance > 400 cd/m
