SECTION 4
SET-UP ADJUSTMENTS
•
The following adjustments should be made when a complete
realignment is required or a new picture tube is installed.
•
These adjustments should be performed with rated power
supply voltage unless otherwise noted.
Controls and switches should be set as follows unless otherwise
noted:
PICTURE control ........................................................... normal
BRIGHTNESS control................................................... normal
Perform the adjustments in the following order :
1. Beam Landing
2. Convergence
3. Focus
Note : Test Equipment Required.
1. Color-bar/Pattern Generator
2. Degausser
3. Oscilloscope
...................................................................................................................................................................
Preparation :
•
In order to reduce the influence of geomagnetism on the set’s
picture tube, face it east or west.
•
Switch on the set’s power and degauss with the degausser.
4-1. BEAM LANDING
1. Input a white signal with the pattern generator.
Contrast
Brightness
2. Position neck assy as shown in Fig4-1.
3. Set the pattern generator raster signal to a green raster.
4. Move the deflection yoke to the rear and adjust with the purity
control so that the green is at the center and the blue and the
red take up equally sized areas on each side.
(See Figures 4-1 through 4-3.)
5. Move the deflection yoke forward and adjust so that the
entire screen is green. (See Figure 4-2.)
6. Switch the raster signal to blue, then to green and verify the
condition.
7. When the position of the deflection yoke has been decided,
fasten the deflection yoke with the screws and DY spacers.

4-2. CONVERGENCE ADJUSTMENT
Preparation :
•
Before starting this adjustment, adjust the focus, horizontal
size and vertical size.
•
Set the Picture Mode to “STANDARD”.
•
Cross hatch / Dot pattern.
4-2-1. Horizontal and Vertical Static Convergence
1. (Moving horizontally), adjust the H.STAT control so that the
red, green and blue dots are on top of each other at the center
of the screen.
2. (Moving vertically), adjust the V.STAT magnet so that the red,
green and blue dots are on top of each other at the center of
the screen.
3. If the H.STAT variable resistor cannot bring the red, green and
blue dots together at the center of the screen, adjust the
horizontal convergence with the H.STAT variable resistor and
the V.STAT magnet in the manner given below.
(In this case, the H.STAT variable resistor and the V.STAT
magnet influence each other, so be sure to perform adjust-
ments while tracking.)

1. Receive the cross-hatch signal and adjust [PICTURE] to
[MIN] and [BRIGHTNESS] to [STANDARD] .
2. Adjust the Y separation axis correction magnet on the neck
assembly so that the horizontal lines at the top and bottom of
the screen are straight.
Note
1. The Red and Blue magnets should be equally far from the
horizontal center line.
2. Do not separate the Red and Blue magnets too far. (Less than
8 mm)
4
BMC (Hexapole) Magnet.
If the red, green and blue dots are not balanced or aligned,
then use the BMC magnet to adjust in the manner described
below.

4-2-2. Dynamic Convergence Adjustment
Preparation:
•
Before starting this adjustment, adjust the horizontal static
convergence and the vertical static convergence
•
Set the PICTURE and BRIGHTNESS to normal.
1. Adjust XCV core.
To able to become balance of XCV on the X axis well.
2. Adjust V-TILT.
Correct the vertical mis-convergence of red and blue of verti-
cally sides on the Y axis.
3. Adjust YCH.
Adjust horizontal mis-convergence of red and blue of verti-
cally sides on the Y axis. Mentioned above steps 2 to 4 are
adjusting respectively perform minuteness tracking.
