4-3-8 Center Convergence Adjustment
1. Warm up the receiver for at least 20 minutes. 2. Adjust the two tabs of the 4 pole magnets to change the angle between them. Superimpose the red and blue vertical lines in the center area of the screen. 3. Adjust the Brightness and Contrast controls for a well defined picture. 4. Adjust the two-tab pairs of the 4 pole magnets, and change the angle between them. Superimpose the red and the blue vertical lines in the center area of the screen.
5. Turn the both tabs at the same time, keeping the angle constant, and superimpose the red and blue horizontal line in the center of the screen. 6. Adjust the two-tab pairs of the 6-pole magnets to superimpose the red and blue line onto the green. (Changing the angle affects the vertical lines, and rotating both magnets affects the horizontal lines.) 7. Repeat adjustments 2~6, if necessary. 8. Since the 4-pole magnets and 6-pole magnets interact, the dot movement is complex (Fig. 5-3).
