If the mentioned default value does not give the required result,
use the following alignment method:
1. Set the external pattern generator to a 100% white pattern,
and connect the RF output to the aerial input of the TV. Set
the amplitude at least 1 mV_rms (60 dBuV) and the
frequency to 475.25 MHz. Use system PAL B/G if possible,
otherwise match the system of your generator with the
received signal in the set.
2. Set "Smart Picture" to "Natural".
3. Set "Dynamic NR" to "off".
4. Put the set in the SAM mode.
5. Select via the WHITE TONE menu, the PATTERN sub-
menu.
6. Set PATTERN to "on".
7. Set NORMAL GREEN to "32".
8. Measure with the colour analyser (Minolta CA100 Colour
Analyser or equivalent), calibrated with the spectra, on the
centre of the screen.
9. Adjust with the cursor left/right command the Red and Blue
register for the right xy-coordinates (see the table below).
10. Repeat the white tone adjustment also for the colour
temperatures COOL and WARM.

Introduction
The microprocessor communicates with a large number of I2C
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 specific
ICs (or functions) is made known by the option codes.

Notes:
•
After changing the option(s), save them with the STORE
command.
•
All changes are disregarded when the OPTIONS submenu
is left without using the STORE command.
•
The new option setting is only active after the TV is
switched "off" and "on" again with the Mains switch (the
EAROM is then read again).
8.4.2
Changing options
Options are used to control the presence / absence of certain
features and hardware. There are two ways to change the
option settings. All changes in the option settings are saved by
selecting STORE and pressing the CURSOR RIGHT key.
Some changes will only take affect after the set has been
switched OFF and ON with the mains switch (cold start).
Changing multiple options by changing option byte values
Option Bytes (OB) makes it possible to set all options very fast.
An option byte represents a number of different options. All
