4 Alignment and Adjustments 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. 2. Make sure the spacing between the PCM assembly and the CRT stem is 29 mm ± 1 mm. 3. Display a green pattern over the entire display area. 4. 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) 5. Repeat steps 4 and 5 using a red pattern and then again, using a blue pattern. Table 4-4. Color Purity Tolerances
Red: Green: Blue: x = 0.640 ± 0.015 x = 0.295 ± 0.015 x = 0.142 ± 0.015 y = 0.323 ± 0.015 y = 0.594 ± 0.015 y = 0.066 ± 0.015
(For 9300K color adjustment: x = 0.283 ± 0.02, y = 0.298 ± 0.02)
6. When you have the PCMs properly adjusted, carefully glue them together to prevent their movement during shipping.
