STATIC CONVERGENCE ADJUSTMENT
[AV-21L11-PH, AV-21L31-PH]
1. Input a crosshatch signal.
2. Using 4-pole convergence magnets, overlap the red and blue lines in
the centre of the screen (Fig. 4) and turn them to magenta (red/blue).
3. Using 6-pole convergence magnets, overlap the magenta(red/blue)
and green lines in the center of the screen and turn them to white.
4. Repeat 2 and 3 above, and make best convergence.
