Feed in the white pattern signal.
•
Before starting, degauss the entire screen.
1.
Input a raster signal with the pattern generator.
2.
Loosen the deflection yoke mounting screw, and set the
purity control to the center as shown in Fig.2.
3.
Turn the raster signal of the pattern generator to
green.
4.
Move the deflection yoke backward, and adjust with the
purity control so that green is in the center and red and
blue are at the sides evenly. (Fig.3)
5.
Move the deflection yoke forward, and adjust so that the
entire screen becomes green. (Fig.1)
6.
Switch over the raster signal to red and blue and confirm
the condition.
7.
When the position of the deflection yoke is determined,
tighten it with the deflection yoke mounting screw.
8.
When landing at the corner is not right, adjust by using
the disk magnets. (Fig.4)
Perform the adjustments in order as follows:
1.
Beam Landing
2.
Convergence
3.
Focus
4.
Screen (G2) and White Balance
Note: Test Equipment Required
1. Color Bar Pattern Generator
2. Degausser
