FTP2.4E AA
Blend Intensity
Use this alignment when you replace the microcontroller, NVM,
or the EBILD. It aligns the level of transparency of the menu-
picture blended into the main-picture. Fixed setting of "16".
8.3.2
2FH ADC Alignment
Only necessary to align, when the A/D converter or NVM is
replaced. Use the default values as mentioned in the table.

White Point
Set ACTIVE CONTROL to "Off".
In the TV -> PICTURE user menu set:
DYNAMIC CONTRAST to "Off".
COLOUR ENHANCEMENT to "Off".
DNR to "Off".
DIGITAL OPTIONS to "Pixel Plus 2".
CONTRAST to "100".
Go to the SAM and select ALIGNMENTS -> WHITE
POINT.
Method 1 (with colour analyser):
Use a 100% white screen as input signal and set the
following values:
COLOR TEMPERATURE: "Tint to be aligned".
WHITE POINT RED: "127".
WHITE POINT GREEN: "127".
WHITE POINT BLUE: "127".
RED BL OFFSET: "7"
GREEN BL OFFSET: "7".
Measure with a calibrated (phosphor- independent) colour
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 white points, the correct x,y
coordinates (see table "White D alignment values").
Tolerance: dx,dy: ± 0.004.
Repeat this step for the other Colour Temperatures that
need to be aligned.
When finished press "Store" to store the aligned values to
the NVM.

Method 2 (without colour analyser):
If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
1. Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).
2. Set the RED, GREEN and BLUE default values according
to the values in the "Tint settings" table.
3. When finished press "Store" to store the aligned values to
the NVM.

Lum. Del.
With this Luminance Delay alignment, you place the luminance
information exactly on the chrominance information (brightness
is pushed onto the colour). Use a colour bar / grey scale pattern
as test signal.
LUM. DELAY PAL BG: Apply a PAL BG colour bar / grey
scale pattern as a test signal. Adjust this parameter until
the transients of the colour part and black and white part of
the test pattern are at the same position. Default value is
"7".
LUM. DELAY PAL I: Apply a PAL I colour bar/grey scale
pattern as a test signal. Adjust this parameter until the
transients of the colour part and black and white part of the
test pattern are at the same position. Default value is "9".
LUM. DELAY SECAM: Apply a SECAM colour bar/grey
scale pattern as a test signal. Adjust this parameter until
the transients of the colour part and black and white part of
the test pattern are at the same position. Default value is
"9".
LUM. DELAY BYPASS: apply a NTSC colour bar/grey
scale pattern as a test signal. Adjust this value until the
transients of the colour and black and white part of the test
area are at the same position. Default value is "6".

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 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).
