6.4 Option Settings
Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.
General: The Service Default Mode (SDM) and Service
Alignment Mode (SAM) are described in chapter 5. 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: 120 - 230 V
AC
/ 50 Hz (± 10%).
• 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 (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heatsinks as ground.
• Test probe: Ri > 10 Mohm, Ci < 20 pF.
• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 Hardware Alignments
There are no hardware alignments foreseen for this chassis,
but below find an overview of the most important DC voltages
on the SSB. These can be used for checking proper functioning
of the DC/DC converters.
6.3 Software Alignments
Put the set in SAM mode (see chapter 5. Service Modes, Error
Codes, and Fault Finding). The SAM menu will now appear on
the screen. Select ALIGNMENTS and go to one of the sub
menus. The alignments are explained below.
The following item can be aligned:
• Whitepoint.
To store the data:
• Press OK on the RC before the cursor is moved to the left.
• In main menu select “Store” and press OK on the RC.
• Press MENU on the RC to switch back to the main menu.
• Switch the set to stand-by mode.
For the next alignments, supply the following test signals via a
video generator to the RF input:
• LATAM models: an NTSC M TV-signal with a signal
strength of at least 1 mV and a frequency of 61.25 MHz
(channel 3).
6.3.1 White Point
• Set “Active control” to “Off”.
• Choose “TV menu”, “TV Settings” and then “Picture” and
set picture settings as follows:
• Go to the SAM and select “Alignments”-> “White point”.
White point alignment LCD screens:
• Use a 100% white screen as input signal and set the
following values (in SAM mode):
– “Color temperature” to “Cool”.
– “Whitepoint red”, “Whitepoint green”, and “Whitepoint
blue” values to “127”.
– “Red BL offset” and “Green BL offset” values to “7”.
With a color analyzer:
Depending on which color analyzer you use (CS-200 or CA-
210), and what kind of panel is mounted in the set (CCFL with
panel codes 231/232, or LED with panel codes 233/234/236),
different values apply. Refer to
• Measure with a calibrated, contactless (max. 25 mm
distance) color analyzer in the centre of the screen.
Consequently, the measurement needs to be done in a
dark environment.
• Adjust one or two registers (so holding one of the White
point registers R, G or B on 127) to obtain the “Cool” x,y
values (see Table 6-1
). Tolerance: dx: ± 0.004, dy: ± 0.004.
• Repeat this step for the “Normal” and “Warm” color
temperatures.
• When finished press “OK” on the RC and then press
“Store” (in the SAM root menu) to store the aligned values
into the NVM.
• Restore the initial picture settings after the alignments.
