This specification sheet is applied to all of the LED LCD TV 

with LC22E 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 °C ± 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 AC  100-240 

V~, 50/60 Hz.

(5)  The receiver must be operated for about 5 minutes prior to 

the adjustment when module is in the circumstance of over 

15.

In case of keeping module is in the circumstance of 0 °C, it 

should be placed in the circumstance of above 15 °C for 2 

hours.

In case of keeping module is in the circumstance of below 

-20 °C, it should be placed in the circumstance of above 15 

°C for 3 hours.

[Caution] 

When  still  image  is  displayed  for  a  period  of  20  minutes  or 

longer  (Especially  where  W/B  scale  is  strong.  Digital  pattern 

13ch  and/or  Cross  hatch  pattern  09ch),  there  can  some 

afterimage in the black level area.

■ Enter Service Mode by pushing “ADJ” key,

■ Enter ADC mode by pushing “► key at “8. ADC Calibration”

■ There are 2 ways for ADC Calibration. ( OTP, External )

*. OTP mode

the  manufacture  line,  OTP  is  used  for ADC  Calibration 

automatically. 

*. External mode

 :  Manual ADC  Calibration.  When  OTP  mode  is  failed, ADC 

calibration should be “OK” by using External mode.

1. Change the ADC type “OTP” by using “►”key.

2. Enter “Start” key. 

3. Check the sign “OK”  below  ADC type.

▪ Setting state confirmation

→  If automatic setting is finished, you confirm IP and MAC 

Address.

- Confirm key input data at the "IN START" MENU Mode.

- In INSTART menu, check these keys.
- In case of CNTV key(only China), Refer to below picture.

▪

 Press "Power on" key of service remote control.

(Baud rate : 115200 bps)

▪

 Connect RS-232C Signal to USB Cable to USB.

▪

 Write Serial number by use USB port.

▪

 Must check the serial number at Instart menu.

(1) Serial number D/L is using of scan equipment.

(2)  Setting  of  scan  equipment  operated  by  Manufacturing 

Technology Group.

(3)  Serial number D/L must be conformed when it is produced 

in production line, because serial number D/L is mandatory 

by D-book 4.0.

* Manual Download (Model Name and Serial Number)

If the TV set is downloaded by OTA or service man, sometimes 

model name or serial number is initialized.(Not always)

It  is  impossible  to  download  by  bar  code  scan,  so  It  need 

Manual download.

1) Press the "Instart" key of Adjustment remote control.

2) Go to the menu "5.Model Number D/L" like below photo.

3)  Input  the  Factory  model  name(ex  47LM6200-CC)  or 

Serial number like photo.

4)  Check  the  model  name  Instart  menu.  →  Factory  name 

displayed. (ex 47LM6200-CC)

5)  Check  the  Diagnostics.(DTV  country  only)  →  Buyer 

model displayed. (ex 47LM6200-CC)

(1) Using RS232 Command

(2) Check the menu on in-start.

*  ADC  adjustment  is  not  needed  because  of  OTP(Auto ADC 

adjustment).

▪ Case : Cool Mode

Purpose :  Adjust  the  color  temperature  to  reduce  the 

deviation of the module color temperature.

Principle :  To adjust the white balance without the saturation, 

Fix  the  G  gain  to  172  (default  data)  and  change 

the others ( R/B Gain ).

Adjustment mode : mode - Cool

▪ Case : Medium / Warm Mode

Purpose :  Adjust  the  color  temperature  to  reduce  the 

deviation of the module color temperature.

Principle :  To adjust the white balance without the saturation, 

Fix  the  one  of  R/G/B  gain  to  192  (default  data) 

and decrease the others.

Adjustment mode : Two modes - Medium/Warm

▪ Adj. condition : normal temperature

1) Surrounding Temperature: 25±5 °C

2) Warm-up time: About 5 Min

3) Surrounding Humidity: 20% ~ 80%

(1) Color Analyzer: CA-210 (LED Module : CH 14)

(2)  Adjustment Computer(During auto adj., RS-232C protocol 

is needed)

(3) Adjustment Remote control

(4) Video Signal Generator MSPG-925F 720p/204-Gray

(Model: 217, Pattern: 49)

-> Only when internal pattern is not available

▪ Color Analyzer Matrix should be calibrated using CS-100.

- LEN: Number of Data Byte to be sent

- CMD: Command

- VAL: FOS Data value

- CS: Checksum of sent data

- A: Acknowledge

Ex) [Send: JA_00_DD] / [Ack: A_00_okDDX]

▪ RS-232C Command used during auto-adjustment.

Ex)  wb 00 00   ->  Begin white balance auto-adj.

 

wb 00 10   ->  Gain adj.

 

ja 00 ff   ->  Adj. data

 

jb 00 c0

 

...

 

...

 

wb 00 1f   → Gain adj. completed

    *(wb 00 20(Start), wb 00 2f(end)) → Off-set adj.

 

wb 00 ff   → End white balance auto-adj.

▪ Adj. Map

(1) Auto adj. method

1) Set TV in adj. mode using POWER ON key.

2)  Zero  calibrate  probe  then  place  it  on  the  center  of  the 

Display.

3) Connect Cable.(RS-232C to USB)

4) Select mode in adj. Program and begin adj.

5)  When adj. is complete (OK Sign), check adj. status pre 

mode. (Warm, Medium, Cool)

6) Remove probe and RS-232C cable to complete adj.

▪  W/B Adj. must begin as start command “wb 00 00” , and 

finish as end command “wb 00 ff”, and Adj. offset if need.
