8.3.2

2FH ADC ALIGNMENT

Only necessary to align, when the A/D convertor or NVM is
replaced. Use the default values as mentioned in the table.

Table 8-2 “2fH ADC alignment”

8.3.3

WHITE D ALIGNMENT

•

Set ACTIVE CONTROL to "Off".

•

In the TV -> PICTURE user menu set:

–

DYNAMIC CONTRAST to "Off".

–

color ENHANCEMENT to "Off".

–

color to "0".

–

CONTRAST to "100".

–

BRIGHTNESS to "43".

•

Go to the SAM and select ALIGNMENTS -> WHITE
POINT.

Method 1 (with color analyser):

•

Use a 100% white screen as input signal and set the
following values:

–

COLOR TEMPERATURE: "Tint to be aligned".

–

WHITEPOINTRED: "127".

–

WHITEPOINTGREEN: "127".

–

WHITEPOINTBLUE: "127".

–

RED BL OFFSET: "7"

–

GREEN BL OFFSET: "7".

•

Measure with a calibrated (phosphor- independent) color
analyser (e.g. Minolta CA-210) in the centre of the screen.
This measurement needs to be done in a dark
environment.

•

Cut off alignment:

Adjust, by means of changing the value

of one or both OFFSET's, to the correct x,y coordinates for
the tint "NORMAL" (see table "White D alignment values").
Tolerance: dx,dy:

0.004.

•

White point alignment:

Adjust by means of decreasing

the value of one or two whiteprints, the correct x,y
coordinates (see table "White D alignment values").
Tolerance: dx,dy:

0.004.

•

Repeat this step for the other Color Temperatures that
need to be aligned.

•

When finished press "Store" to store the aligned values to
the NVM.

Table 8-3 White D alignment values

Method 2 (without color analyser):

If you do not have a color analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).

Select a color TEMPERATURE (e.g. COOL, NORMAL, or
WARM).

Set the RED, GREEN and BLUE default values according
to the values in the "Tint settings" table.

When finished press "Store" to store the aligned values to
the NVM.

8.3.4

LUM. DEL.

With this Luminance Delay alignment, you place the luminance
information exactly on the chrominance information (brightness
is pushed onto the color). Use a color bar / grey scale pattern
as test signal.

•

LUM. DELAY PAL BG:

Apply a PAL BG color bar / grey

scale pattern as a test signal. Adjust this parameter until
the transients of the color part and black and white part of
the test pattern are at the same position.
Default value is "

•

LUM. DELAY PAL I:

Apply a PAL I color bar/grey scale

pattern as a test signal. Adjust this parameter until the
transients of the color part and black and white part of the
test pattern are at the same position.
Default value is "

•

LUM. DELAY SECAM:

Apply a SECAM color bar/grey

scale pattern as a test signal. Adjust this parameter until
the transients of the color part and black and white part of
the test pattern are at the same position.
Default value is "

•

LUM. DELAY BYPASS:

apply a NTSC color bar/greyscale

pattern as a test signal. Adjust this value until the transients
of the color and black and white part of the test area are at
the same position.
Default value is "

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.

•

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).
