Figure 8-3 Geometry Alignments
1.
Before starting the vertical alignment, set (in SAM) the
following parameters to "0":
–
VER. SHIFT,
–
VER. SCOR,
–
VER. U_LIN,
–
VER. L_LIN.
2.
Set SERV. BLK to "on", to blank the lower half of the
screen.
3.
Adjust the "VERTICAL SHIFT" potentiometer (R3642 on
the LSP) until the picture is centred (to the mechanical
centre of the picture tube), and switch SERV. BLK to "off".
4.
Adjust VER. U_LIN and VER. L_LIN such, that upper and
lower horizontal lines of the crosshatch pattern are just
visible.
Use then the following software regulations to modify the
geometry:
1.
VER. AMPL (Vertical Amplitude): Align for the vertical
picture centre, range from -32 to +32.
2.
VER. SHIFT (Vertical Shift): Compensating for any gain
error in amplifier, adjust range from -32 to +32 to the proper
amplitude.
3.
VER. SCOR (Vertical S-Correction): Align for equal height
of the blocks in the top, the bottom and the middle, range
from -63 to +63.
4.
HOR. SHIFT (Horizontal Shift): Adjust for the horizontal
centre of the screen, range from -127 to +128.
Next step is to align the East/West geometry.
1.
First, set the parameters EW_5 and EW_6 to "0"
2.
EW. WIDTH (East-West Width): This sets the (overall)
horizontal size of the picture on the screen. Range from -
63 to +63 (with the following EW alignments, these lines
can be straightened).
3.
EW_1 (East-West parameter 1): Has effect on the length of
the upper part of the vertical E/W lines.
4.
EW_2 (East-West parameter 2): Has effect on the length of
the vertical E/W lines just below EW_1.
5.
EW_3 (East-West parameter 3): Has effect on the length of
the vertical E/W lines just below EW_2.
6.
EW_4 (East-West parameter 4): Has effect on the length of
the vertical E/W lines just below EW_3.
7.
EW_5 (East-West parameter 5): Has effect on the length of
the vertical E/W lines just below EW_4.
8.
EW_6 (East-West parameter 6): Has effect on the length of
the vertical E/W lines just below EW_5.
9.
EW_7 (East-West parameter 7): Has effect on the length of
the vertical E/W lines just below EW_6.
10.
EW_8 (East-West parameter 8): Has effect on the length of
the vertical E/W lines just below EW_7.
11.
EW_9 (East-West parameter 9): Has effect on the length of
the vertical E/W lines just below EW_8.
12.
EW_10 (East-West parameters 10): Has effect on the
length of the lowest part of the vertical E/W lines.
13.
HOR. BOW (Horizontal Bow): Align the EW parabola to be
symmetrical, range from -63 to +63.
14.
HOR. PARALLEL (Horizontal Parallel): Align for straight
vertical lines on the picture sides, range from -63 to +63.
15.
HOR. LIN (Horizontal Linearity): Align for equal width of
horizontal blocks on the left, the right and the centre, range
from 0 to +127.
16.
HOR. IN_PIN (Horizontal Inner Pincushion): Align for the
inner straight vertical lines, range from 0 to +32.
8.3.3
WHITE TONE
In the WHITE TONE sub menu, the colour values for the
different colour temperatures can be changed.
The colour temperature mode (NORMAL, DELTA COOL,
DELTA WARM) can be selected per colour (R, G, and B) with
the RIGHT/LEFT cursor keys. The mode or value can be
changed with the UP/DOWN cursor keys.
First, the values for the NORMAL colour temperature must be
selected. Then the offset values for the DELTA COOL and
DELTA WARM mode can be selected. Note that the alignment
values are non-linear.
