Note: To secure the correct position of the deflection yoke, three rubber wedges are used. They are ultimately to
be placed as shown in Figure 3c or Figure 4c.
1. Apply a crosshatch pattern to the antenna/cable input terminal.
2. Use the Menu Up/Down keys to select Normal Green, and use the Menu Left key to set Normal Green to
minimum.
3. Tilt the yoke up and down to converge the red and blue vertical lines at the 6:00 and 12:00 positions and the
red and blue horizontal lines at the 3:00 and 9:00 positions (refer to Figure 5). When the correct position has
been found, place a rubber wedge between the yoke and the CRT. If the yoke is tilted up, place wedge one
as shown in Figure 3a; if it is tilted down, place wedge one as shown in Figure 4a.
4. Tilt the yoke to the left and right to find the point of best possible convergence of the red and blue lines at
the edges, top and bottom of the screen as shown in Figure 6. When the correct position is located, place
wedges two and three as shown in Figure 3b or Figure 4b.
5. Remove wedge one and place it in the final position as shown in Figure 3c or Figure 4c.
6. Use the Menu Up/Down keys to select Normal Green, and use the Menu Right key to set Normal Green to
maximum.
7. Proceed to the White Balance Setup.
