1. Receive a monoscope pattern.
2. Confirm that Coarse convergence data (Service mode1) for R,G and B is 0.
3. Set that Fine convergence data (Service mode1) is clear (no correction).
4. Set that V-Pos data (Service mode1) is [100].
5. Set that H-Pos data (Service mode1) is [55].
6. Set that H-Parallel data (Service mode1) is [8].
Procedure:
1. Cover the Red, Blue CRT lens, projecting Green only.
2. Adjust green centering magnet (DY) if the projected green horizontal/vertical line does not
line up with the screen horizontal/vertical center line.

8. Adjust green centering magnets until the center of the monoscope pattern line up with the
screen center line.
9. Cover the Green, Red CRT lens, projecting Blue only.
10. Adjust blue centering magnets to position the center of the blue raster W2 away from the
center of the green raster.
11. Cover the Green, Blue CRT lens, projecting Red only.
