6.1 General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
• Power supply voltage: 90 - 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 (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heat sinks as ground.
• Test probe: R > 10 MΩ, C
i
• Use an isolated trimmer/screwdriver to perform
alignments.
6.2 Hardware Alignments
Not applicable.
6.3 Software Alignments
Put the set in SAM mode (see Chapter

• 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 with a signal
strength of at least 1 mV and a frequency of 475.25 MHz
• US/AP-NTSC 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).
• 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 Display adjustment
You can use the default values. The default values are average
values coming from production.
• Enter SAM mode.
• Select a colour temperature (e.g. COOL, NORMAL, or
WARM).
• Set the RED, GREEN and BLUE default values according

6.4.1 Introduction
The microprocessor communicates with a large number of I
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) plus integrated Ambilight control)
is made known by the option codes.
Notes:
• After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left,
select STORE and press OK on the RC.
• The new option setting is only active after the TV is
switched "off" / "stand-by" and "on" again with the mains
switch (the NVM is then read again).
6.4.2 Option Code Overview
Enter SAM mode to check the option codes. they could not be
edited in the NVM.
6.4.3 Display Code Overview
Press the following key sequence on a standard RC
transmitter: "062598" directly followed by MENU and "xxx",
where "xxx" is a 3 digit decimal value of the panel type: see
column "Display Code" in
Code, restart the set immediately.
