The following adjustments should be made when a
complete realignment is required or a new picture
tube is installed.
Set the controls as follows unless otherwise noted:
VIDEO model ..................................................... Standard
PICTURE control .................................................. normal
BRIGHTNESS control .......................................... normal
Perform the adjustments in the following order :
1. Beam Landing
2. Convergence
3. Focus
4. Screen(G2)
5. White Balance
Note :
Test Equipment Required.
1. Pattern Generator
2. Degausser
3. DC Power Supply
4. Digital Multimeter
5. 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.

BEAM LANDING
Picture Mode: DYNAMIC
1. Input a white signal with the pattern generator.
Contrast
Brightness
2. Set the pattern generator raster signal to a green
raster.
3. Move the deflection yoke to the rear and adjust with
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 2-1 through 2-4.)
4. Move the deflection yoke forward and adjust so that
the entire screen is green. (See Figure 2-1.)
5. Switch the raster signal to blue then to red and verify
the condition.
6. When the position of the deflection yoke has been
decided fasten the deflection yoke with the screws
and DY spacers.
7. If the beam does not land correctly in all the corners,
use a magnet to adjust it. (See Figure 2-4.)
