4.2. Colour Purity

 1. Set Bright and Contrast controls to their maximum

positions.

 2. Operate the TV set over 60 minutes.
 3. Full degauss the picture tube by using an external

degaussing coil. By rotating R-B static convergence
magnet.

 4. Apply a crosshatch pattern signal and adjust roughly the

static convergence magnets.

 5. Apply a green pattern signal.
 6. Loosen a clamp screw for the Deflection Yoke and move

the Deflection Yoke as close to the purity magnet as
possible.

 7. Adjust the purity magnet so that a vertical green field is

obtained at the center of the screen.

 8. Slowly press the Deflection Yoke and set it where a uniform

green field is obtained.

 9. Adjust roughly the Low Light controls and make sure that a

uniform white field is obtained.

 10. Tighten the clamp screw.

4.3. Convergence

 1. Apply a crosshatch pattern signal and set Contrast control

to the maximum position.

 2. Adjust Bright control to obtain a clear pattern.
 3. Adjust Red and Blue line at center of the screen.

 4. Adjust Red and Blue with Green line at center of the screen

by rotating (RB)-G static convergence magnet.

 5. Lock convergence magnets with silicone sealer.
 6. Remove the DY wedges and slightly tilt the Deflection Yoke

vertically.

 7. Fix the Deflection Yoke by re-inserting the DY wedges.
 8. If purity error is found, repeat “Colour Purity” adjustment.
