4.7.2 Adjustment Procedure
1. Set the color temperature to "6500K".
2. Fully degauss the front, both sides, and top of the picture tube with an external degaussing coil.
3. Input a crosshatch pattern signal and adjust the convergence by horizontally and vertically
positioning the static convergence magnet and deflection yoke.
4. Change the input signal to a 100% white pattern signal and adjust the BRIGHT and
CONTRAST controls to obtain a digital voltmeter reading of 14.3 V±0.8 V.
5. Adjust the purity magnet to obtain a uniform landing at each place of nearly 2 cm from the
right and left screen edges. At this time, if it is difficult to obtain correct purity, finely adjust
the fore-and-aft position of the deflection yokeand its tilt and fine-tune the purity magnet.
Note:
6. When adjusting the purity magnet, first set the adjustment ring with a small dilation and the
other with no dilation to the same position at the top and then adjust them in symmetrical
opposite directions each other.
7. Display a red pattern and check its purity.
8. Display a blue pattern and check its purity.
9. Display the 100% white pattern and check its white quality.
10. If there is a problem in steps 6 through 8, repeat steps 2 through 8 until its problem disappears.
