2.EWW (East-West Width): This sets the (overall) horizontal size of the picture on the screen. Range from 0 to +63.

3.EWP (East-West Parabola): Align for the vertical lines of the test picture to be straight lines. Range from 0 to +63.

4.HB (Horizontal Bow): Align the EW parabola to be symmetrical, range from 0 to +63.

5.HP (Horizontal Parallel): Align for straight vertical lines on the picture sides, range from 0 to +63.

6.UCP (Upper Corner Parabola): Align for the vertical lines in the upper corners of the screen to be straight. Range from 0 to +63.

7.LCP (Lower Corner Parabola): Align for the vertical lines in the lower corners of the screen to be straight. Range from 0 to +63.

8.EWT (East-West Trapezium): Align for equal length of the horizontal lines in the upper and lower parts of the screen. Range from 0 to +63.

Now, select “Double Lines” mode, and again align the following vertical screen geometry setting:

1.VS (Vertical Slope); First activate menu item SBL (Service Blanking = ON), so the lower part of the test picture is no longer visible. Then adjust the Vertical Slope. Align for the horizontal line in the middle of the test picture to line up with the boundery between the (still visible) upper part of the screen and the (invisible) lower part of the screen. Range from 0 to +63. After this, switch the SBL to OFF again.

8.3.3White Tone

In the WHITE TONE sub menu, the colour values for the different colour temperatures can be changed.

The colour temperature mode (NORMAL, DELTA COOL, DELTA WARM) can be selected per colour (R, G, and B) with the RIGHT/LEFT cursor keys. The mode or value can be changed with the UP/DOWN cursor keys.

First, the values for the NORMAL colour temperature must be selected. Then the offset values for the DELTA COOL and DELTA WARM mode can be selected. Note that the alignment values are non-linear.

Alignment

Normally, no adjustments are needed.

If the white tone alignment values used in CSM of the the TV set do not give the required result, use the following alignment method:

1.Set the external pattern generator to a 100% white pattern, and connect its RF output to the aerial input of the TV. Set

the amplitude to at least 1 mVRMS (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 "0".

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.

8.4.1Introduction

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 options setting is only active after the TV is switched "off" and "on" again with the Mains switch (the EAROM is then read again).

8.4.2Changing 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 options are controlled via option bytes (OB1 to OB13; each “OB” number represents 16 bits; bit numbers that are not used are omitted in the second column). Select an Option Byte you want to change with the CURSOR UP/DOWN keys, and key in the new value. See the table for more details. An explanation per option is listed in paragraph "Option Bit Definition".

Changing a Single Option

It is also possible to change an option one at a time. Therefore, select the option with the CURSOR UP/DOWN keys and change its setting with the LEFT/RIGHT keys.
