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
(e.g. measure audio signals
in relation to
AUDIO_GND).
Caution: It is
not allowed
to use heat sinks as ground.
• Test probe: R
i
> 10 MΩ, C
i
< 20 pF.
• Use an isolated trimmer/screw
driver to perform
alignments.
6.2 Hardware Alignments
Not applicable.
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 RGB Align and go to one of the sub menus.
The align
ments are explained below.
The following items can be aligned:
• White point
To store the data:
• Press OK on the RC before the cu
rsor is m
oved to the
left
• Select “Store” and press OK on the RC
• Switch the set to stand-by mode.
For the next alignments, supply the
following
test signals via a
video generator to the RF input:
• EU/AP-PAL models: a PAL B/G TV-signal w
i
th a signal
strength of at least 1 mV and a frequency of 475.25 MHz
• US/AP-NT
SC models: an NTSC M/N TV-signal with a
signal strength of at least 1 mV and a frequency of
61.25 MHz (channel 3).
• LAT
AM models: an NT
SC M TV-signal with a signal
strength of at least 1 mV and a frequency of 61.25 MHz
(channel 3).
6.3.1 Display adjustment
You can use the default values. The default values are average
values coming from produ
ction.
•
Enter SAM mode.
• Select a colour temperature
(e.g. C
OOL, NORMAL, or
WARM).
• Set the RED, GREEN and BLUE default values according
to the values in
Table 6-1.
• When finished press OK on the RC, then press STORE to
store the aligned values to the NVM.
•
Restore the initial picture settings after the alignments.

automatically to the TV / VGA / HDMI / AV sources.
6.4 Option Settings
6.4.1 Introduction
The microprocessor communicates with a large number of I
2
C
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence / absence of these
MT5366 ICs (back-end advanced video picture improvement
IC which offers motion estimation and compensation features
(commercially called HDNM) is made known by the option
codes.
6.4.2 Option Code Overview
Enter SAM mode to check the option codes. They can not be
edited in the NVM.
6.4.3 Display Code Overview
Press the following key sequence on a standard RC
tran
smitter: “062598” directly follow
ed by MENU and “xxx”,
where “xxx” is a 3 digit decimal value of the panel type: see
column “Display Code” in
Table 6-2. When the value is
accepted and stored in NVM, the set will switch to Stand-by, to
indicate that the process h
as been completed.

6.5 Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service
repair shop (SSB repair on component level) implies the reset
of the NVM on the SSB.
A repaired SSB in Service should get the service Set type
“00PF00000000
00” and Production code “00000000000000”.
