Colour Purity
1. Set the Brightness and Contrast controls to their
maximum positions.
2. Operate the TV set for 60 minutes.
3. Fully degausse the picture tube by using an external
degaussing coil.
4. Apply a crosshatch pattern signal and adjust the static
convergence magnets to the approximately correct
position.
5. Receive a black and white signal.
6. Set the control as follows:
Red................minimum
Green.............minimum
Blue...............minimum
Press the Shipping button on the remote control twice to
select CRT Adjustment Mode to select low light.
7. Loosen the clamp screw for the Deflection Yoke A in
Fig. 10 and move the Deflection Yoke as close to the
purity magnet as possible.
8. Adjust the purity magnetic rings so that a vertical green
field is obtained at the centre of the screen.
Fig. 6
9. Slowly push the Deflection Yoke and set it where a
uniform green field is obtained.
Fig. 21
10. Re-adjust the Low Light controls to their correct settings
and make sure that a uniform white field is obtained.
11. Tighten the clamp screw A in Fig. 10.
Convergence
1. Apply a crosshatch pattern signal and Normalize
Contrast control to the maximum positions.
2. Adjust Brightness until the grey position of the
crosshatch pattern just becomes black.
3. Adjust the Red and Blue line at the centre of the screen
by rotating the R-B static.
Fig. 8
4. Adjust Red and Blue with Green line at centre of the
screen by rotating (RB)-G static convergence magnetic
rings.
5. Lock convergence magnets with silicone sealer.
6. Remove the DY wedges and slightly tilt the Deflection
Yoke vertically and horizontally to obtain the good
overall convergence.
Fig. 9
7. Fix the Deflection Yoke by reinserting the DY wedges.
Refer to Fig. 10.
8. If purity error is found, repeat “Colour Purity”
