5.1. Adjustment Preparation
▪ W/B Equipment condition
CA210: CH14, Test signal: Inner pattern(80IRE)-LED Module
▪ Above 5 minutes H/run in the inner pattern. ("power on" key
of Adjustment remote control)
* The spec of color temperature and coordinate.
▪ ROW LED W/B Table in process of aging time (Only LGD
ROW module)
* Connecting picture of the measuring instrument
(On Automatic control)
Inside Pattern is used when W/B is controlled. Connect to
auto controller or push Adjustment Remote control POWER
ON → Enter the mode of White-Balance, the pattern will
come out.
* Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight
around is blocked. (Illumination is less than 10 lux).
(2) Adhere closely the Color analyzer(CA210) to the module
less than 10 cm distance, keep it with the surface of the
Module and Color analyzer's prove vertically.(80° ~ 100°).
(3) Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 5 minutes.
- Using 'no signal' or 'POWER ONLY' or the others, check
the back light on.

Color Temperature : COOL, Medium, Warm.
One of R Gain/G Gain/ B Gain should be kept on 0xC0, and
adjust other two lower than C0.(When R/G/B Gain are all
C0, it is the FULL Dynamic Range of Module)
* Manual W/B process using adjust Remote control.
■ Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000.
■ Operate the zero-calibration of the CA100+ or CA-210,
then stick sensor to the module when adjusting.
■ After enter Service Mode by pushing “ADJ” key,
■ Enter White Balance by pushing “►” key at “9. White
Balance”.
■ For manual adjustment, it is also possible by the following
sequence.
(1) Set TV in Adj. mode using “P-ONLY” key on remote
controller and then operate heat run longer than 15
minutes.(If not executed this step, the condition for W/B
may be different.)
(2) Push “Exit” key.
(3) Enter White Balance mode by pushing the ADJ key and
select “9. White Balance”. When KEY (►) is pressed,
206 Gray internal pattern will be displayed.
(4) Zero Calibrate the probe of Color Analyzer, then place it
on the center of LCD module within 10cm of the surface
(5) Select each items (Red/Green/Blue Gain) using
▲/▼(CH +/-) key on Remote control.
(6) Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
