2. Switch on the set’s power and degauss with the degausser.
3-1. Beam Landing

and Green take up equally sized areas on each side of the
screen. [See Fig.3-1 - 3-3].
4. Move the deflection yoke backwards and adjust so that the
entire screen becomes Red. [See Fig.3-1]
5. Switch the raster signal to Blue, then to Green and verify
the condition.
6. When the position of the deflection yoke has been
determined, fasten the deflection yoke with the screws.
If the beam does not land correctly in all the corners, use a
magnet to correct it. [See Fig.3-4]

@ Tilt the VSTAT magnet and adjust the static convergence by
opening or closing the V.STAT magnet.
The movement of the magnets interact with each other and so
the respective dot position should be monitored while carrying
out this adjustment.
Use the H.STAT VR to adjust the Red, Green and Blue dots so
that they coincide at the centre of the screen
(by moving the dots in the horizontal direction).
