4.7. VRS Adjustment
1. PREPARATION
a. Set DY to CRT not to tilt up and down and left and right
deflection. (Fig. 11)
b. Set CY to CRT and set CY magnet primarily.
Pur Mg : Set Pur Mg that 2 magnets are vertical
position.
VRS Mg : Set VRS Mg that 2 magnets are side position.
c.
Set geomagnetic correction DAC [0].
FIG. 11
2. ADJUSTMENT
a. Receive the white balance pattern.
b. Adjust V-CENTER.
c.
Set R,B CUT OFF to minimum (0), and set G CUT OFF
to center.
d. Receive the aging pattern.
e. Set 2 magnet of vertical position to up and down equally
so that center part of CRT. (Fig. 12)
Fig. 12
4.8. Colour Purity
1. Operate the TV set for over 60 minutes.
2. Receive a purity pattern signal. (white pattern)
3. Set Bright and Contrast controls to their maximum
positions.
4. Set V-POS to 128.
5. Adjust roughly the static convergence magnets.
6. Fully
degauss
the
picture
tube
using
an
external
degaussing coil.
7. Loosen a clamp screw for the deflection yoke and move the
deflection yoke as close to the purity magnet as possible.
8. Adjust the purity magnet so that a vertical green field is
obtained at the center of the screen.
9. Slowly press the deflection yoke and set it where a uniform
green field is obtained.
10. Adjust roughly the Low Light controls and make sure that a
uniform white field is obtained.
11. Tighten the clamp screw.
4.9. Convergence
1. INSTRUMENT
a. Helmhortz device
2. PREPARATION
a. Set the Helmhortz device to local magnetic field.
Horizontal : 0 ± 0.03 x10
-4
T
b. Receive the cross hatch pattern.
c.
Picture menu : DYNAMIC Normal and adjust BRIGHT
DAC until gray portion of cross hatch.
d. Set DY to CRT not to tilt (up and down and left and
right).
3. ADJUSTMENT
a. Static convergence Adjustment
a. Make sure that magnets are positioned shown in
Fig. 13.
b. Adjust 4-pole magnets (Fig. 13) to align center dots
of R and B and adjust 6-pole magnets to align center
dots to G.
c.
After adjustment, secure magnets with magnet lock
of white lacquer.4
*Beams move with rotating when static magnets are
turned.
Rotational reduce of beams differs by angle of two
magnets.
Therefore, repeat magnet adjustments several times
