2.IN THE PURITY AND CONVERGENCE ADJUSTMENTS LIST PAGE 8
PURITY ADJUSTMENT
1.When replacing picture tube or deflection yoke, mount deflection yoke and purity-convergence magnets assembly properly. See Figure 1. Position the picture tube facing east or west. Demagnetize the picture tube and receiver using an external degaussing coil. Set receiver to Service Menu No. 073 (no vertical sweep) while degaussing.
2.Place the yoke on tube neck fully against glass.
2a. Place the CPM on the tube neck aligning the center of the purity magnet tabs (2 pole) over center of Focus Gap (G3 & G4). See Figure 2.
3.Connect a color bar generator to the antenna terminal. Switch the generator to a white field. Move yoke backward on the neck until a uniform white field is obtained.
4.Allow 30 minutes warm up on a blank white field (high intensity grayscale).
Note: If white field cannot be obtained, check Grayscale Adjustments on page 6.
5.Set the picture controls to the Auto levels. Select a green raster, either with the signal generator or by adjusting the bias controls. If a signal generator is used for this step, Skip to Step 10. If the bias controls will be used, go to step 6.
6.Adjust Service Menu No. 015 RB (R-Bias), No. 016 GB (G- Bias), and No. 017 BB (B-Bias) data to 0 each.
7.Select Service Menu No. 073 (no vertical sweep).
8.Adjust the screen control counterclockwise until the horizontal scan lines is no longer visible.
9.Select Service Menu No. 016 GB (G-Bias) and raise the data to produce green raster. If retrace lines appear, reduce screen control slightly.
10.Pull yoke back on the tube neck to obtain three-color raster (blue, green and red).
11.Adjust the angle between the two purity magnet tabs to center the vertical green belt in the picture tube. Do not
rotate tabs. See Figure 3.
12.Slowly slide the deflection yoke forward until a uniform green screen is obtained.
13.Check the purity of the red and blue screens for uniformity. Turn off other colors to check (use bias controls) or use generator. If necessary, readjust the yoke position until all screens are pure.
14.If bias controls and screen control were used to set purity, reset Grayscale and Brightness Level. Refer to Grayscale Adjustment on page 6 and Brightness Level Adjustment on page 7.
15.Confirm that the yoke is not tilted. Tighten the yoke mounting screw. Adjust convergence next.

2.IN THE PURITY AND CONVERGENCE ADJUSTMENTS LIST PAGE 8
PURITY ADJUSTMENT
1.When replacing picture tube or deflection yoke, mount deflection yoke and purity-convergence magnets assembly properly. See Figure 1. Position the picture tube facing east or west. Demagnetize the picture tube and receiver using an external degaussing coil. Set receiver to Service Menu No. 073 (no vertical sweep) while degaussing.
2.Place the yoke on tube neck fully against glass.
2a. Place the CPM on the tube neck aligning the center of the purity magnet tabs (2 pole) over center of Focus Gap (G3 & G4). See Figure 2.
3.Connect a color bar generator to the antenna terminal. Switch the generator to a white field. Move yoke backward on the neck until a uniform white field is obtained.
4.Allow 30 minutes warm up on a blank white field (high intensity grayscale).
Note: If white field cannot be obtained, check Grayscale Adjustments on page 6.
5.Set the picture controls to the Auto levels. Select a green raster, either with the signal generator or by adjusting the bias controls. If a signal generator is used for this step, Skip to Step 10. If the bias controls will be used, go to step 6.
6.Adjust Service Menu No. 015 RB (R-Bias), No. 016 GB (G- Bias), and No. 017 BB (B-Bias) data to 0 each.
7.Select Service Menu No. 073 (no vertical sweep).
8.Adjust the screen control counterclockwise until the horizontal scan lines is no longer visible.
9.Select Service Menu No. 016 GB (G-Bias) and raise the
data to produce green raster. If retrace lines appear, reduce screen control slightly.
10.Pull yoke back on the tube neck to obtain three-color raster (blue, green and red).
11. Adjust the angle between the two purity magnet tabs to center the vertical green belt in the picture tube. Do not rotate tabs. See Figure 3.
12.Slowly slide the deflection yoke forward until a uniform green screen is obtained.
13.Check the purity of the red and blue screens for uniformity. Turn off other colors to check (use bias controls) or use generator. If necessary, readjust the yoke position until all screens are pure.
14.If bias controls and screen control were used to set purity, reset Grayscale and Brightness Level. Refer to Grayscale Adjustment on page 6 and Brightness Level Adjustment on page 7.
15.Confirm that the yoke is not tilted. Tighten the yoke mounting screw. Adjust convergence next.
