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” adjustment.
