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  to  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) Auto AV Color Balance.
(2) Adjustment of White Balance.
(3) Auto Component Color Balance adjustment.

- standard equipment : MSPG925FA.

(4) Auto RGB Color Balance adjustment.

- standard equipment : MSPG925FA
(  At  DVR  model  Case,  Please  check  DVR  function  like

following list )

(5) Checking DVR Function and HDD
*  Check  DVR  Function  as  follow  on  4.2  and  find  HDD  failure
under malfunction.

1) Assemble MAIN , DVR Board.
2) HDD Format in progress words will create automatically.  
3) Please, wait for 30~40 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.

: refer to Fig.2

1) After receiving 100% Full White Pattern, HEAT RUN.
2) Connect + terminal of D.M.M to Va pin of P812, connect

- terminal to GND pin of P812.

3)  After  turning  VR501,  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 P812, connect

– terminal to GND pin of P812.

2)  After  turning  VR401,  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 cable 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.
