If you turn on a still screen more than 20 minutes (Especially
Digital pattern(13 CH), Cross Hatch Pattern), an afterimage
may occur in the black level part of the screen.

Each PCB Assy must be checked by Check JIG Set before
assembly. (Especially, be careful Power PCB Assy which can
cause Damage to the PDP Module.)

(1) Color Analyzer : CA-210 (CH 10), CA-100, CA-100+

=> To adjust color temperature of PDP, CS-1000 is the

Color Analyzer(CA-210) and should be set to use CH 10
in which white, red, green, and blue color are corrected.
Conduct the adjustment according to the coordinates for
White Balance adjustment in the table below.

(2) Computer for adjusting (necessary for the automatic

adjustment, possible to communicate with the RS-232C,
Baud Rate : 115200)

(3) Video Signal Generator MSPG-925F 720p, 216Gray

(Model :217, Pattern 78)

[Full white 216gray]

[

1) Environment illuminance

Adjust it to 10 LUX or less at the place where the light
source such as lamp should be blocked at maximum.

2) Probe location

- PDP: Locate the Color Analyzer (CA-100, CA-100+,

CA210) close to the module surface to measure and
adjust

- LCD: Maintain the Color Analyzer (CA-210) close to the

module surface by 10cm or less and keep the probe of
the Color Analyzer perpendicular to the module surface
(80°~ 100°).

(Automatic Adjustment)

Use the internal pattern to adjust White Balance. The pattern
is automatically given when the automatic adjustment device
is connected or when a user presses ADJ on the remote
controller to start Ez Adjust and then selects 6.White-Balance.

Basically it uses the internal pattern but when internal pattern
is not possible, you can select HDMI input for adjustment.
Through the option at the most bottom part of the Ez Adjust
Menu 7.White Balance menu, you can select NONE, INNER
and HDMI, and the default is set to INNER. When the
adjustment cannot be done with the internal pattern, you can
select HDMI input for adjustment. 

For manual adjustment, press the ADJ KEY of the adjustment
R/C to enter Ez Adjust 7.White-Balance, and the pattern is
automatically displayed. (When you set the Option to INNER,
the default is always set to INNER)

(1) Connect the set according to the internal pattern or HDMI

input in accordance with measuring device connection
diagram. 

(2) Set the Baud Rate of RS-232C to 115200. It is set to

115200 as default.

(3) Connect the RS-232C Cable to the set.
(4) Connect the HDMI Cable to the set. (Limited to the set with

HDMI option)

(5) Select and adjust the model applicable to PB82C chassis

from the adjuster.

(1) Execute POWER ON(

Â

) of the adjustment R/C to execute

automatic adjustment or set the Baud Rate to 115200.

(2) Always start adjustment with “wb 00 00” and end

adjustment with “wb 00 ff” (Adjust the offset if necessary)

(3) RS-232C command used for the automatic adjustment

(internal pattern)

(1) Required Test Equipment: CA-210 (CH-10), CA-100(CH-

10), CA-100+(CH-10)
=> To adjust color temperature of PDP, CS-1000 is the

Color Analyzer and should be set to use CH 10 in which
white, red, green, and blue color are corrected. Conduct
the adjustment according to the coordinates for White
Balance adjustment in the table below.

(2) Enter the ‘Ez - Adjust’ by pressing the ADJ on the Service

R/C.

(3) Select 10.TEST PATTERN using the CH + / - KEY and

press the Enter KEY to execute a heat run for more than
30 minutes. 

(4) Zero Calibrate CA-100+/CA-100 Probe, and stick the

sensor to the center of PDP module surface when you
adjust.

Execute a Zero Calibration for CA-210 Probe and put it at
distance of less than 10Cm from the PDP module surface
center during the adjustment. 

(5) Select ‘7. White-Balance’ of ‘Ez - Adjust’ by pressing the

ADJ KEY on the Service R/C. Then enter adjustment mode
by pressing the Right KEY (

G

) .

(The internal pattern of full white appears by pressing 

G

)

(6) The adjustment is conducted in three levels of color

temperature; COOL, MEDIUM, and WARM.

1) When R GAIN is set to 192

- Control G GAIN and B GAIN by lowering from 192.

2) When B GAIN is set to 192

- Control R GAIN and G GAIN by lowering from 192.

3) When G GAIN is set to 192

- Control R GAIN and B GAIN by lowering from 192.

One of R Gain / G Gain / B Gain should be kept on 192,
and adjust other two lower than 192.
(When R/G/B GAIN are all 192, it is the FULL DYNAMIC
Range of Module)

(7) Use the Vol. +, - key for adjustment.
(8) When the adjustment is completed, press the ENTER (

Á

KEY) button to move to the Ez –Adjust screen. Press the
