4-3-4 (d) WHITE BALANCE ADJUSTMENT VERIFICATION
Refer to the procedure for 9300K, section 4-3-2 (d).
4-3-5 Luminance Uniformity Check
Luminance is considered uniform only if the ratio
of lowest to highest brightness areas on the screen
is not less than 7.5:10.

PROCEDURE
1.
Adjust the Focus VR on the FBT to display the
sharpest image possible.
2.
Use Locktite to seal the Focus VR in position.
4-3-7 Color Purity Adjustment
Color purity is the absence of undesired color.
Conspicuous mislanding (unexpected color in a
uniform field) within the display area shall not be
visible at a distance of 50 cm from the CRT
surface.
CONDITIONS

Cut off point at the center
of the display area
Note:
Color purity adjustments should only be
attempted by qualified personnel.
PROCEDURE
For trained and experienced service technicians
only.
Use the following procedure to correct minor
color purity problems:
1.
Make sure the display is not affected by
external magnetic fields.
Very carefully break the glue seal between the
2-pole purity convergence magnets (PCM), the
band and the spacer.
Make sure the spacing between the PCM
assembly and the CRT stem is 29 mm ± 1 mm.
Display a green pattern over the entire display
area.
Adjust the purity magnet rings on the PCM
assembly to display a pure green pattern.
(Optimum setting: x = 0.295 ± 0.015,
y = 0.594 ± 0.015)
Repeat steps 4 and 5 using a red pattern and
then again, using a blue pattern.

(For 9300K color adjustment: x = 0.283 ± 0.02, y = 0.298 ± 0.02)
7.
When you have the PCMs properly adjusted,
carefully glue them together to prevent their
movement during shipping.
