b. White balance fine regulation:
(1)Receive VGA-480 timing, full white square
pattern.
(2) Adjust BRIT. VR. to MIN., CONT. VR. to MAX..
(3) Adjust VR601,602,603 to make x=0.281 + 0.01,
y=0.311 + 0.01, are measured by color
Analyzer.
(4) Change the BRIT. VR to the click point and the
CONT. VR: between 1 ~ 2FL, then adjust
VR604,605,606 (BIAS VR) 'to. get X=0.281 +
0.005, Y=0.311+0.005, are measured by color
Analyzer. ere os
(5) If the white balance is.not.met, repeat step (2)
* ADJUSTMENT FOR CONVERGENCE
(1) Produce a magenta crosshatch on the display.
(3)Also adjust the brightness to the desired
condition. — 7
(4) Vertical red and blue lines are converged by
varying the angle between the two tabs of the
4 pole magnets on the PCM assembly. (See
diagram below)
(5) Horizontal red and blue lines are converged by
moving the two tabs at the same time keeping
the angle between them constant.
(7) Vertical green and magenta lines are
