8.3.4 Geometry
The geometry alignments menu contains several items to align
the set, in order to obtain correct picture geometry.
Figure 8-4 Geometry alignments
1. Connect an external video pattern generator to the aerial
input of the TV-set and input a crosshatch test pattern. Set
the generator amplitude to at least 1 mV and set frequency
to 61.25 MHz (channel 3).
2. Set 'Smart Picture' to NATURAL (or MOVIES).
3. Activate the SAM menu (see chapter 5 “Service Modes,
...”).
4. Go to the GEOMETRY sub menu.
5. Choose HORIZONTAL or VERTICAL alignment.
Now the following alignments can be performed:
Horizontal
• Horizontal Parallelogram (HP). Align straight vertical
lines in the top and the bottom; vertical rotation around the
center.
• Horizontal Bow (HB). Align straight horizontal lines in the
top and the bottom; horizontal rotation around the center.
• Horizontal Shift (HSH). Align the horizontal center of the
picture to the horizontal center of the CRT.
• East West Width (EWW). Align the picture width until the
complete test pattern is visible.
• East West Parabola (EWP). Align straight vertical lines at
the sides of the screen.
• Upper Corner Parabola (UCP). Align straight vertical lines
in the upper corners of the screen.
• Lower Corner Parabola (LCP). Align straight vertical lines
in the lower corners of the screen.
• East West Trapezium (EWT). Align straight vertical lines
in the middle of the screen.
• H60 (Delta HSH for 60Hz, if present). Align straight
horizontal lines if NTSC system is used (60 Hz) i.s.o. PAL
(50 Hz). Default value is “9”.
Vertical
• Service blanking (SBL). Switch the blanking of the lower
half of the screen “on” or “off” (to be used in combination
with the vertical slope alignment).
• Vertical Shift (VSH). Align the vertical centering so that
the test pattern is located vertically in the middle. Repeat
the 'vertical amplitude' alignment if necessary.
• Vertical slope (VS). Align the vertical center of the picture
to the vertical center of the CRT. This is the first of the
vertical alignments to perform. For an easy alignment, set
SBL to “on”.
• Vertical Amplitude (VAM). Align the vertical amplitude so
that the complete test pattern is visible.
• Vertical S-Correction (VSC). Align the vertical linearity,
meaning that vertical intervals of a grid pattern must be
equal over the entire screen height.
• Vertical Zoom (VX, if present). The vertical zoom is
added in for the purpose of development. It helps the
designer to set proper values for the movie expand or
movie(16x9) compress. Default value is “25”.
• V60 (Delta VAM for 60Hz, if present). Align straight
vertical lines if NTSC system (60 Hz) is used i.s.o. PAL (50
Hz). Default value is “-2”.
8.3.5 Audio
No alignments are needed for the audio sub menu. Use the
given default values.
QSS (Quasi Split Sound)
• For NICAM/2CS sound system (EU/AP, except for AP-
NTSC): set to “On”.
• For AV-Stereo sound system (sets without NICAM): set to
“On”.
• For all other sets (NAFTA/LATAM/AP-NTSC): set to “Off”.
FMI (Freq. Modulation Intercarrier)
• For NICAM/2CS sound system (EU/AP, except for
APNTSC): set to “On”.
• For AV-Stereo sound system (sets without NICAM): set to
“Off”.
• For dBx/non-dBx sound systems: set to “On”.
NICAM Alignment
• For sets with NICAM/2CS (EU/AP, except for AP-NTSC)
sound system: set to “79”.
• For all other sets (NAFTA/LATAM/AP-NTSC): set to “63”.
