5.3 VIDEO COLOR TEMPERATURE ADJUSTMENT
(STD)
Preparation
(1) Same as “Video Color Temperature adjustment:
(HIGH)”. For 55” video level changes to 0.700Vp-p.
Adjustment
(1) Perform the following adjustment with the remote
control.
(2) Set the CRT color analyzer (CA-100) at the center of
the panel.
(3) Set color temperature to “STD”.
(4) Ensure that Adjustment R/G/B DRIVE (STD) are all
set as FF.
(5) After receiving White raster signal, step down the two
(or one) among Adjustment R/B/G DRIVE (STD) and
adjust the value shown below.
Specification
Video Color temperature (STD)
42"
x = 0.314
± 0.005
y = 0.327 ± 0.005
(Color temp: 6500K )
55"
x = 0.314
± 0.005
y = 0.327 ± 0.005
(Color temp: 6500K )
At least one of the data should be FF.

the panel.
(3) Ensure that Adjustment R/G/B DRIVE (B/W) are all
set as FF.
(4) After receiving White Raster signal, step down the
two (or one) among Adjustment R/B/G DRIVE (B/W)
and adjust the value shown below.
Specification

5.5 PC COLOR TEMPERATURE ADJUSTMENT
(HIGH)
Preparation
(1) This adjustment should be done after video color
temperature adjustment.
(2) Confirm that it’s set as factory adjustment mode.
(3) Input white raster (ratio 100%) into RGB terminals at
VGA (75) 0.7V (No set-up).
(4) Set AVC to shipment.
(5) Confirm that the screen size is ‘FULL’.
Adjustment
(1) Perform the following adjustment with the remote
control.
(2) Set the CRT color analyzer (CA-100) at the center of
the panel.
(3) Ensure that Adjustment R/G/B DRIVE (HIGH) are all
set as FF.
(4) After receiving PC signal, step down the two (or one)
among Adjustment R/B/G DRIVE (HIGH) and adjust
the value shown below.
Specification
PC Color temperature (HIGH)
42"
x = 0.268
± 0.005
y = 0.283 ± 0.005
(Color temp: 12000K)
55"
± 0.005
x = 0.268
y = 0.283 ± 0.005
(Color temp: 12000K)
At least one of the data should be FF.
(5) Write Adjustment value of video color temperature to
the equivalent PC color temperature adjustment
items..
Video Color Temperature
PC Color Temperature
R/G/B DRIVE (MEDIUM) data
R/G/B DRIVE (MEDIUM) data
R/G/B DRIVE (STD) data
R/G/B DRIVE (STD) data
R/G/B DRIVE (B/W) data
R/G/B DRIVE (B/W) data
Remarks
(1) Color temperature should be adjusted under the
condition in which the screen is the brightest, thus
the initial value for adjustment is set its maximum.
(2) Adjustment is made by reducing brightness only.
Reduce a bright color for adjustment.
(3) Video color temperature & Adjustment No. are the
same, but addresses in the memory are different,
thus there’s no problem.
5.6 COLOR TEMPERATURE CORRECTION
SETTING
This adjustment should be done after color
temperature adjustment (for 42” only).
(1) Set service adjustment menu to “DEVICE ADJUST
