These specifications are applicable for all LCD TV models
with an AL-04DA chassis that are manufactured by the
Manufacturing Group of the Display Business Division, or
any of its related manufacturers.

2.1 This chassis is the non-charging type chassis for

which the power unit is insulated. Therefore, the
insulated type transformer is not required but it is
recommended that it be used between the power
supply line and chassis input side before running the
chassis, in order to protect the adjustment equipment.

2.2 Adjustment should be made in the correct sequence.

However, the order can be changed for mass
production purposes.

2.3 The suggested surrounding temperature is 25

±

5°C,

and suggested relative humidity is 65

±

10% for the

adjustment of the chassis, unless specified.

2.4 The input voltage should be maintained at 110V and

60MHz.

2.5 The receiver should run for about 15 minutes before

starting adjustment, unless specified.

- Run prior operation after receiving 100% White

pattern (06CH).

(OR, 9. White Pattern state in Ez-Adjust.)

- How to enter into the White Pattern
1) Press the Power ON key in the adjustment remote

control.

2) Or, press the ADJ key on the adjustment remote

control to enter into Ez-Adjust and select 9. White

Pattern using CH +/- key. Then, press the OK (

)

key to display 100% Full White Pattern.

* In this mode, the SET can be put on HEAT RUN

without a separate signal generator.

Note) If you leave the stop image on for more than 20

minutes, you must be careful because an
afterimage will appear on the black level section.
(Applies to internal digital pattern (13CH) and cross
hatch pattern (09CH) with clear black/white
contrast, in particular). 

<Precaution>
Each PCB assembly must be checked using the check jig set
before the full assembly process. (The power PCB assembly
can damage the LCD module irreparably.)

3.1. Extended Display Identification Data (EDID) and

Display Data Channel (DDC) download

3.1.1 Overview

Developed by VESA, the EDID function is designed
to support the "plug & play" function, which enables
the computer to configure the user environment
automatically through communication with the
monitor. 

3.1.2 Entering the HDMI EDID Data
1) Equipment

- PC and DDC adjustment jig (PC serial to D-sub

connection device)

- DDC recording software (EDID data write & read)
- D-Sub terminal
- Need separate HDMI cable connection jig. 

3.2. Adjusting AD9883A-Set

3.2.1. Overview

AD9883A-Set adjustment automatically sets the
optimal black level, and readjusts the RGB
differences in analog -> digital converter.
Adjustment is made separately for the component
mode and RGB-DTV mode input.

3.2.2. Equipment

Adjustment remote control: 801GF (802B, 802F,
802R) or MSPG925FA Pattern Generator(It should
support 720P horizontal 100% color bar patter
display, and the output level should be accurately
corrected to 0.7

±

0.1Vp-p.)

Adjustment pattern: 720P/60Hz HozBar Pattern
(Format No. 217, Pattern No. 65)

3.2.3 Signal input method

Connect the component output and RGB D-Sub
output of the Pattern Generator to the component 1
and RGB D-Sub jack of the set.

- 11 -

3.2.4. Adjustment method

A) When entering the component, input 100%

Horizontal Color Bar Pattern (HozTV30Bar) of the
supportable 720P mode, and select Component 1
or Component 2 input, and select Normal image.

B) Wait for at least one second after receiving the

signal and press the ADJ key on the adjustment
remote control to enter into Ez-Adjust. Then, select
"1. AD9883A-Set" and press the + key for
automatic adjustment.

C) If adjustment is completed successfully, the

"AD9883A Component Success" message will be
displayed. Otherwise, the "AD9883A Configuration
Error" message will be displayed.

D) If the adjustment for component AD9883A is

finished, it will automatically switch to RGB-DTV
mode, and the above-mentioned pattern will be
displayed. If adjustment is successfully completed,
"AD9883A RGB_DTV Success" message will be
displayed.

E) If adjustment is not completed successfully, check

the pattern or adjustment condition and try again.

F) If adjustment is completed successfully, press the

ADJ key to exit from the adjustment mode.

3.3. Adjusting White Balance

3.3.1 Equipment

- Color Analyzer (CA-100 or equivalent item)
- Automatic adjustment device (Needed for automatic

communication, Baud rate: 115,600)

- Pattern Generator (MSPG-925FA): Equipment with

DVI output.

- Pattern: High light 80% Full White

3.3.2 Measurer Connection Diagram (Automatic

3.3.3. Manual White Balance Adjustment

When adjusting after carrying out zero calibration for
CA-100, the sensor should be tightly fixed on the
LCD module surface. Take the following steps for
manual adjustment.
A) Press the ADJ key on the adjustment remote

control to enter into "Ez-Adjust."

B) Select "9. White Pattern" using CH +/- key and

press the OK key. Then, perform Heat Run for
more than 30 minutes.

C) Make the Digital Pattern Generator supply Full

White Pattern signal.

(Connect the external input to "HDMI".)

D) Fix the sensor to the screen center and press the

ADJ key on the adjustment remote control to
select "6. White balance" in "Ez-Adjust". Then,

press the right direction key (

) to enter into the

adjustment mode.

E) Adjust the high light using R Gain, G Gain, and B

Gain.

F) Use Volume +/- key for adjustment.

3.3.4. Adjustment Target value

- Brightness value
- Target value

X coordinate value / Y coordinate value / 
White Balanc / Special items.

3.4 Video (uPD) - Automatic Set Adjustment

This automatic adjustment function narrows the color
difference between the main and sub screen of the RF
and video signal. Adjustment is made for both RF
mode and video 1 mode. The signal source of RF is
internal 02Ch, and the signal source for video 1 is
100% full color bar.

3.5 RS232C Operation Check

Press In-start in the adjustment remote control and
enter '6. Baud Rate' menu. Then, change the baud
rate to 9600 and check RS232C operation.
