Alignments EN 122 FTL2.1E, FTL2.2E 8.
SAM menu. Alignment is correct when the DC voltage is just
below 3.5 V.
IF AFC Tuner 2
Use the same procedure as described above (under IF AFC)
with the set switched to the DW source.
IF LPRIME AFC Tuner 2
Use the same procedure as described above (under IF
LPRIME AFC) with the set switched to the DW source.
Tuner AGC Tuner 2
Use the same procedure as described above (under TUNER
AGC) with the set switched to the DW source. Measure on pin
1 of the DW Tuner.
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 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".
– COLOUR ENHANCEMENT to "Off".
– COLOUR to "0".
– CONTRAST to "100".
– BRIGHTNESS to "43".
• 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".
– WHITEPOINTRED: "127".
– WHITEPOINTGREEN: "127".
– WHITEPOINTBLUE: "127".
– RED BL OFFSET: "7"
– GREEN BL OFFSET: "7".
• Measure with a calibrated (phosphor- independent) colour
analyser in the centre of the screen. Use a contactless
analyser (e.g. Minolta CA-210) to align an LCD TV. The
colour analyser may not touch the screen surface.
Consequently, the measurement needs to be done in a
dark environment.
Note: The colour analyser needs to be calibrated for LCD!
• Adjust, by means of decreasing the value of one or two
whitepoints, 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.
Table 8-3 White D alignment values
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.

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 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/
greyscale 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 ".
