Chassis.

(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 instrument.

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

25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The input voltage of the receiver must keep 100-220V~,

50/60Hz.

(5) Before adjustment, execute Heat Run for 30 minutes.
(6) Before you measure optical characteristic(W/B, Color

Temperature,etc), You must change ot User2 mode in
Picture menu.

(1) Channel memory

1) Download the channel data from BOM to EEPROM by

using LGIDS.

(2) Option adjustment following BOM

1) Push the ADJ key in the Adjust Remocon.
2) Input the Option Number that was specified in the BOM,

into the Shipping area.

3) Select “Tool Option1/ Tool Option2/ Area Option” by

using 

D

/

E

(CH+/-) key, and press the number key(0~9)

consecutively.

ex) If the value of Tool Option1 is 7, input the data using

number key “7”(Fig.1).

(3) Color carrier Adjustment.

(1) Adjustment of White Balance.

( At DVR model Case, Please check DVR function like

following list)

(2) Checking DVR Function and HDD. 

- Check DVR Function as follow on 4.2 and find HDD

failure under malfuncion.

1) Assemble MAIN Board.
2) HDD Format in progress words will create automatically.  
3) Please, wait for 5~15 seconds.

(1) HDD Format in progress.

(2) HDD Format completed.

(1) Connect USB memory stick to SET.
(2) Set power off -> On

- DVR s/w will be installed automatically.

After HEAT-RUN mode, must have AC-Power off for DVR
function check.

Only support file name -> MTL.bin in USB memory stick.

(Va, Vs Voltage adjustments)

D.M.M. 1EA

: refer to Fig.2

1) After receiving 100% Full White Pattern, HEAT RUN.
2) Connect + terminal of D.M.M to Va pin of P801, connect

- terminal to GND pin of P801.

3) After turning VR902, voltage of D.M.M adjustment as

same as Va voltage which on label of panel right/top.
(Deviation; ±0.5V)

1) Connect + terminal of D.M.M to Vs pin of P801, connect

– terminal to GND pin of P801.

2) After turning VR901, voltage of D.M.M adjustment as

same as Va voltage which on label of panel right/top.
(Deviation; ±0.5V)

* Press the FRONT-AV Key on R/C for converting input mode.

(Change RS-232 Host : pc, BaudRate : 115200bps)

Each PCB assembly must be checked by check JIG set.
(Because power PCB Assembly damages to PDP Module,
especially be careful)

* Use the proper signal cabel for EDID Download

- Analog EDID : Pin3 exists
- Digital EDID : Pin3 exists

* Never connect HDMI & DVI-D & DVI-A Cable at the same time.
* Use the proper cables below for EDID Writing
* HDMI 1 and HDMI2 is different each other. So you have to

Download different EDIT File.
