, then save it into SRGB color temperature. then exit factory setting area.
H. After modulation, it’s necessary to check if the white balance accords with the normal specification. If not,
needs reset. then exit factory setting area.
REMARK: 1. adjust the balance , it’d better not change G bias ;
2. the white balance spec (except special customer spec).
4. Focus Adjustment:
A. Set mode7 1024×768@85Hz with character full page.
B. Under the RECALL state.
C. Then adjust focus VR1 to a fine vertical line.
D. Adjust focus VR2 to a fine horizontal line.
E. Repeat step C & D,after that ,set the Focus VR,G2 VR with the white lacquer.
5. Purity Adjustment
A. Be sure that the display is not being exposed to any external magnetic fields.
B. Ensure that the spacing between the Purity, Convergence, Magnet, (PCM), assembly and the CRT stem is
29mm. (See below diagram)
C. Produce a complete, red pattern on the display. Adjust the purity magnet rings on the PCM assembly to
obtain a complete field of the color red. This is done by moving the two tabs in such a manner that they
advance in an opposite direction but at the same time to obtain the same angle between the two tabs,
which should be approximately 180'.
D. Check the complete blue and complete green patterns to observe their respective color purity. Make minor
adjustments if needed.
