3.1. ADC Process
(1) ADC
- Enter Service Mode by pushing "ADJ" key,
- Enter Internal ADC mode by pushing "►" key at "7. ADC
Calibration".
<Caution> Using "P-ONLY" key of the Adjustment remote
control, power on TV.
If there is no Component Input, disappear “ADC Comp” message.
* ADC Calibration Protocol (RS232)
Adjust Sequence
▪ aa 00 00 [Enter Adjust Mode]
▪ xb 00 40 [Component1 Input (480i)]
▪ ad 00 10 [Adjust 480i Comp1]
▪ xb 00 60 [RGB Input (1024*768)] (only LD21B)
▪ ad 00 10 [Adjust 1024*768 RGB] (only LD21B)
▪ aa 00 90 End Adjust mode
* Required equipment : Adjustment remote control.

4.1. Adjustment Preparation
▪ W/B Equipment condition
CA210
: CCFL/EEFL -> CH9, Test signal: Inner pattern(80IRE)
LED -> CH14, Test signal: Inner pattern(80IRE)
▪ Above 5 minutes H/run in the inner pattern. (“power on” key
of adjust remote control)
▪ Edge LED W/B Table in process of aging time (Only LGD
Edge LED Module except AUO, CMI, IPS Module)
CA210 : CH 14, Test signal : Inner pattern (80IRE)
* 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 R/C 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.
