The Smartloader is a function implemented in the service software of SEE designed LE750 series intended to easily     
replicate the user settings of one TV into another. These settings include (but not restricted to): picture and audio, tun-
ing set-up, language and country selection, PIN, child locked programs… Factory adjustments are not copied as they 
are different for every TV.
The Smartloader makes possible the user data to be stored in a memory device connected to the USB terminal of the 
TV that is used as reference and later load those data into other TVs by using their respective USB terminal.

How it works.
In reference TV:

1. Insert a memory device in the USB slot.
2. Enter in service mode, select SmartLoader (Clone TV) menu.
3. Press “OK”.
4. Select “Save data” and press OK in the remote control.
5. Wait until “OK:0” is displayed, the fi le has been successfully created in the root directory of the memory device.
In case of error, an explanation message is shown. 

In TV to be cloned:

1. Insert a memory device with a fi le in it obtained following the above procedure.
2. Enter in service mode, select SmartLoader menu.
3. Select “Load data” and press OK button in the remote control.
4. After some seconds, “OK: 0” is displayed.  In case of error, an explanation message is shown.
5. Reboot the TV to load the new settings.

Very important: All the TVs must have the same software version and hardware.

The following information describes how to use RS-232 commands on the LE65x/75x series. We have also pro-
vided information on the adaptor cable required.

RS-232 cable 
The LE65x/75x series do not support RS232 connectivity with a standard D-Sub 9 pin connector and instead use a 
3.5mm jack input. To use this input for RS232 control it is necessary to adapt a connector cable. Please follow the 
instructions below on how to construct the cable. Be sure that you use a commercial available RS232 to TTL 3.3V 
level converter; nowadays there are a lot of USB-to-RS232 level converters on the market. You can fi nd some dif-
ferent models through FTDI company (www.ftdi.com).

Please take a look on:

TV set signal requirement is shown in the below picture.

You should open a connection between a computer and the TV set, for this reason you need a RS-232 terminal 
application. You can use the “Hyperterminal” included with any Windows release, but also you can use TeraTerm as 
freeware application (http://ttssh2.sourceforge.jp/index.html.en).

Some small Teraterm adjustments:

• 

Set on “Setup > Terminal” menu the “New Line > Receive” as “CR+LF” and activate “Local Echo”.

• 

Set on “Setup > Serial port...” menu the following parameters.

Baudrate: 115200 bauds, Bits: 8, Parity: none, Stop Bits: 1, Flow control: none.

How to Check connection with TV set.
• 

With TV set in operation condition connect the RS232 tool to the SERVICE socket.

• 

Open a connection session with the terminal program.

• 

Press “ENTER” on the terminal screen.

• Confi rm that TV set send “ERR”.
In fact this “ERR” message indicates that TV set is ready to receive commands.

How to Enter in “K MODE”.
• Send 

“KMOD1056”.

• 

Wait until receive “OK” from TV set. Confi rm that TV set screen is show a “K” on the screen with the model and 
size of your TV set. As example LC-60LE752.

How to Exit from “K MODE”.
• Send 

“KMOD8723”.

• 

Wait until receive “OK” from TV set. Confi rm that TV set has removed the “K” form the screen.

How to Change Model in “K MODE”.
After replacing the Main Unit, check the Model Name in the following procedure.
• 

Send “KRCT1” to change to LE75x model.

• 

Send “KRCT2” to change to LE65x model.

Confi rm that OSD indicates the right MODEL after sending the command.

How to Adjust VCOM in “K MODE”(ONLY for 60 inches model).
After replacing the LCD panel or LCD control PWB, adjust the VCOM in the following procedure.

• 

Place the colorimeter probe at center of the screen and set the FLICKER measurement mode on it.

• 

Activate the VCOM pattern using VCPT0001 command.

• 

Set the initial value of VCOM as 090 with command “VCMW1090”.

• Read 

the 

fl icker value on colorimeter.

• 

Set other values of VCOM trying to minimize it.

• 

Please use the “VCMW1XXX” command to set different values (where XXX are digits 0 to 9). Generally values 
around 090 are the best ones.

• 

To hide the VCOM pattern and close the adjustment procedure please uses “VCPT0000” command.
