These instructions are applied to all of the LCD TV, LA84D.

(1) Because this is not a hot chassis, it is not necessary to use

an isolation transformer. However, the use of isolation
transformer will help protect test equipment.

(2) Adjustments must be done in the correct order.
(3) The adjustments must be performed in the circumstance of

20±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The input voltage of the receiver be must kept 220V, 60Hz

when adjusting.

(5) The receiver must be operational for about 15 minutes

prior to the adjustments.  

(6) Perform preliminary operation after receiving 100% White

Pattern (06CH). (Or 3. White Pattern status of Ez-Adjust)

(7) White Pattern entry method

1) Enter into Ez-Adjust by pressing the ADJ key on the

adjustment R/C.

2) 100% FULL WHITE PATTERN appears if pressing the

OK (

A

) key after selecting the 3.WHITE PATTERN with

the CH + / - KEY.

* It is possible to heat run the set without a separate
signal generator in this mode.

Caution : Care must be taken as afterimage phenomena
may occur about the black level part of screen If leaving
pause image turned on for more than 20 minutes
(especially inner digital pattern (13 CH), Cross Hatch
Pattern (09CH) with significant black/white contrast).

•  If “0xB6(RGB)” address of EEPROM “0xB2” isn’t “0xAA”, we

adjust once more 

•  We can confirm the ADC values from “0xB0~0xB5(RGB)”

addresses in a page “0xA2”

• If “0xBF(480i)/0xC8(1080i)” address of EEPROM “0xA2”
isn’t “0xAA”, we adjust once more 

• We can confirm the ADC values from “0xB9~0xBE(480i)/

2) EDID DOWNLOAD JIG
3) HDMI Cable, D-Sub cable

1) Configure the download environment as shown at the

adjustment wiring diagram and turn on the PC.

2) Execute the DDC program. (EDID Data Write & Read)
3) Go to Model -> Open, and select the EDID data of the

desired model.

4) Check the item to download from the <Test> item

4-1) HDMI & RGB: Check Digital & Analog
4-2) (Only)HDMI: Check Digital only

5) Press ESC(Cancel Mode) -> F8(Auto Mode). (Set Auto

Detecting)

6) Connect the desired signal cable to the set.
7) Make sure that the popup "Proceed to write?" is displayed.
8) Press the Enter key or the space key to download.
9) After downloading, check the OK message and disconnect

the connected cable.

* It is possible to download on only POWER ON MODE.
