You must adjust DTV 29 Channel and insert PCMCIA CARD
to socket.

(1) If PCMCIA CARD works normally, normal signals display

on screen.
But it works abnormally, “No CA module” words display on
screen.

- Before adjusting White-balance , the AV ADC should be done.
- If ADC status were “NG”, Need to ADC adjustment.

Caution: Press the POWER ON KEY on R/C before W/B

adjustment.

- Color Analyzer (CS-1000, CA-100+(CH.10), CA-210(CH.10))

[

Please adjust CA-100+ / CA-210 by CS-1000 before

measuring

--> You should use Channel 10 which is Matrix

compensated (White, Red, Green, Blue revised) by CS-
1000 and adjust in accordance with White balance
adjustment coordinate.

rate : 115200 bps

(On Automatic control )

Inside PATTERN is used when W/B is controlled. Connect to
auto controller or push control R/C INSTART —> Enter the
mode of White-Balance, the pattern will come out.

(1) Adjust in the place where the influx of light like floodlight

around is blocked. (illumination is less than 10ux).

(2) In case of PDP: Measure and adjust after sticking the

Color Analyzer (CA-100+, CA210) to the side of the
module. 

In case of LCD: Adhere closely  the Color Analyzer (
CA210 ) to the module less than 10cm distance, keep it
with the surface of the Module and Color Analyzer’s Prove
vertically.(80~100°).

(3) Aging time  

1) After aging start, keep the power on (no suspension of

power supply) and heat-run over 5 minutes.

2) In case of PDP, keep white pattern using inside pattern.
3) In case of LCD, using ’no signal’ or ‘full white pattern’ or

the others, check the back light on.

O

Auto Adjustment Map(RS-232C)

1) Zero Calibrate CA-100+ / CA-210, and when controlling,

stick the sensor to the center of PDP module surface.

2) Press the ADJ KEY on R/C and enter EZ ASJUST

Select “2. White Balance” and press 

G

(VOL +)

Set test-pattern on and display inside pattern. 

3) Control is carried out on three color temperatures, COOL,

MEDIUM, WARM. 
(Control is carried out three times)

<Temperature: COOL>

- R-Cut/ G-Cut / B-Cut is set to 64
- Control R-Gain and G-Gain.
- Each gain is limited to 192

<Temperature: MEDIUM>

- R-Cut/ G-Cut / B-Cut is set to 64
- Control R-Gain and G-Gain.
- Each gain is limited to 192

<Temperature: WARM>

- R-Cut/ G-Cut / B-Cut is set to 64
- Control G-Gain and B-Gain.
- Each gain is limited to 192
