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 CATHODE and enter the value "15" (for all picture
tubes).
2. Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).
3. Set the RED, GREEN and BLUE default values according
to the values in the "Tint settings" table.
4. RED BL OFFSET: the Black Level can be aligned very
precisely here. The default value is "7".
5. GREEN BL OFFSET: the Black Level can be aligned very
precisely here. The default value is "7".

8.3.3 LUM. DEL. (Luminance Delay)
With this 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
"9".
• 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
"11".
• 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 "10".
8.3.4 GEO-NOR
Note: For all geometry alignments, use an external pattern
generator with a crosshatch pattern.
Figure 8-8 Geometry Alignments
"Geo-Nor" stands for Normal Geometry, and is aligned in Pixel
Plus mode (at 75 Hz).
Service tip: When the set is equipped with a rotation coil, use
this menu item to check its correct alignment. If alignment is not
correct, go to the user menu, choose SETUP, GENERAL, and
TILT ADJUST. With the use of a crosshatch test pattern, align
it to achieve a correct horizontal picture.
V. SLOPE
Aligns the zero crossing of the frame deflection to the
mechanical middle of the picture tube.
1. First set the start conditions for 16:9 sets: V. S-
CORRECTION value on "16" for the 28 inch, "18" for the 32
inch, or "20" for the 36 inch sets.
2. Align V. SLOPE (during alignment, the lower half of the
picture is blanked) so that the middle line of the test pattern
is matched with the edge of the pattern transient in the
middle of the picture.
3. Repeat the alignment if necessary.
