Note: The Service Alignment Mode (SAM) are described in
chapter 5. Service Modes, Error Codes, and Fault Finding
.
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: 90 - 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 12 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.
6.2 Hardware Alignments
Not applicable.
6.3 PC mode display adjustment
6.3.1 General set-up
Alignment set-up diagram:
The alignment has to be done in a subdued lighted room. The
ambient Light may be maximum 5 NIT.
Equipment requirement:
Minolta Colour Analyser CA-210 / CS-200 and Quantum Data
802BT Video Test Generator.
Input signal types:
Apply full white pattern to the HDMI input, apply 1080p 60 Hz.
Input injection point:
HDMI input.
6.3.2 Alignment method
Alignment set-up:
1. Minimum of 12 minutes soaking time before carrying out
point alignment.
2. Input pattern for White Point alignment.
3. press “0 0 0 1 8 3 MUTE” to enter SmartModule ByPass
Mode.
4. The alignment is done for “Cool”, “Normal” and “Warm”.
5. Use a contactless analyzer for LCD display.
Method of Alignment:
1. Place the colour sensor of the meter at the centre of the
screen with standard orientation (at 0 degree orientation).
2. Set the meter in (T, Duv) or (x, y).
3. Set the picture format to Unscaled, set the light sensor to
off, set the brightness to 50, set the colour to 50 and set the
contrast to 100.
4. Set colour temperature to “COOL”.
5. White point red, White point green, White point blue
register must be set to maximum value of 128.
6. Press “0 6 2 5 9 6 INFO” to enter the back-end factory
mode.
7. At SAM mode menu, adjust the SCALER_GAIN_R,
SCALER_GAIN_G, SCALER_GAIN_B values to meet
“COOL” colour coordinates specification below. Then store
those values to NVM.
6.3.3 Alignment Request in the center of the screen
Pre-check panel uniformity is OK and Pre-check “White
Original Surface Luminance”, Scaler R/G/B gain = 128.
• 32" panel : > 450 cd/m
2
.
• 37" panel : > 400 cd/m

.
• 42" panel : > 400 cd/m

.
Adjusting “Scaler Gain” in factory mode. These R/G/B gain
value < 128 to avoid saturation at 11-step grey pattern.
This group setting of colour temp. will be applied automatically
in TV / VGA / HDMI / AV source.
Table 6-1 The 1931 CIE chromaticity (x, y) by CS-200
If no colour analyser is available, the default values can be
used. This is the next best solution. The default values are
averaged measured production values.
• Select a COLOR 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 remote control, then press
STORE (in the SAM root menu) to store the aligned values
to the NVM.
• Restore the initial picture settings after the alignments.

In SAM, after reset “Reset option code”, restart the set
immediately.
