ELECTRICAL ADJUSTMENT
3-2 G-Bright / G-
Contrast
1. Group: AD
Subject: G-BRIGHT
(Black level)
G-CONTRAST
(White level)
2. Feed the window pattern
signal containing 91%
(0.64Vp-p) G signal and
0% level.
(Process/Gamma interac-
tion)
(SVGA or XGA)
Input 5 RGB input
1. Observe the 0% window pattern chromaticity on
CA100.
2. Starting with a bit dropout screen, vary the G-
Bright setting until the bright green "y" setting
turns toward the black tone and stays there. Now
raise the setting by one point and adjust to the
point where the first bit dropout is encountered
(the setting changes over 5/1000).
3. Observe the 91% G signal chromaticity on CA100.
4. Starting with a bit dropout screen, vary the R-
Contrast setting until the bright green "y" set-
ting turns toward the black tone and stays there.
Now raise the setting by one point and adjust to
the point where the first bit dropout is encoun-
tered (the setting changes over 5/1000).
1 Initialization of
EEPROM
1. Turn on the power (the
lamp lights up) and warm
up the system for 15 min-
utes.
1. Carry out the following setting.
Using the remote controller or press S2002 to
enter the process mode, and execute SS2 on SS
menu.
2 Adjustment of
CW index
1. Input the gradation pat-
tern of RGB.
(SVGA60Hz or XGA)
2. Select the following
group and subject.
Group: DLP
Subject: INDEX DELAY
1. Select subject and make adjustment so that the
lamp gradation patterns of R, G and B should be
smooth without noise.
3-1 R-Bright / R-
Contrast
1. Group: AD
Subject: R-BRIGHT
(Black level)
R-CONTRAST
(White level)
2. Feed the window pattern
signal containing 91%
(0.64Vp-p) R signal and
0% level.
(Process/Gamma interac-
tion)
(SVGA or XGA)
Input 5 RGB input
1. Observe the 0% window pattern chromaticity on
CA100.
2. Starting with a bit dropout screen, vary the R-
Bright setting until the bright red "x" setting turns
toward the black tone and stays there. Now raise
the setting by one point and adjust to the point
where the first bit dropout is encountered (the
setting changes over 5/1000).
3. Observe the 91% R signal chromaticity on CA100.
4. Starting with a bit dropout screen, vary the R-
Contrast setting until the bright red "x" setting
turns toward the black tone and stays there. Now
raise the setting by one point and adjust to the
point where the first bit dropout is encountered
(the setting changes over 5/1000).
