2-2. CONVERGENCE
Before starting this adjustment, adjust the focus,
horizontal size and vertical size.
Receive dot/hatch signal
Pic mode: Soft
(1) Horizontal and Vertical Static Convergence
1. (Moving vertically), adjust the V.STAT magnet so that
the red, green and blue dots are on top of each other
at the centre of the screen.
2. (Moving horizontally), adjust the H.STAT VR control so
that the red, green and blue dots are on top of each
other at the center of the screen.
3. If the H.STAT variable resistor cannot bring the red,
green and blue dots together at the center of the
screen, adjust the horizontal convergence with the
H.STAT variable resistor and the V.STAT magnet in the
manner given below.
(In this case,the H.STAT variable resistor and the
V.STAT magnet influence each other so be sure to
perform adjustments while tracking).
4. BMC (Hexapole) Magnet.
If the red, green and blue dots are not balanced or
aligned, then use the BMC magnet to adjust in the
manner described below.
