Precautions when using the USB device
• Only a USB storage device is recognizable.
• If the USB storage device is connected through a USB hub, the
device is not recognizable.
• A USB storage device using an automatic recognition program
may not be recognized.
• A USB storage device which uses its own driver may not be
recognized.
• The recognition speed of a USB storage device may depend on
each device.
• Please do not turn off the TV or unplug the USB device when
the connected USB storage device is working. When such device
is suddenly separated or unplugged, the stored files or the USB
storage device may be damaged.
• Please do not connect the USB storage device which was
artificially maneuvered on the PC. The device may cause the
product to malfunction or fail to be played. Never forget to use
only a USB storage device which has normal music files or image
files.
• Please use only a USB storage device which was formatted as a
FAT or NTFS file system provided with the Windows operating
system. In case of a storage device formatted as a different utility
program which is not supported by Windows, it may not be
recognized.
• Please connect power to a USB storage device which requires
an external power supply. If not, the device may not be
recognized.
• Please connect a USB storage device with cable is offered by
USB maker. If connected with cable is not offered by USB maker
or an excessively long cable, the device may not be recognized.
• Some USB storage devices may not be supported or operated
smoothly.
• File alignment method of USB storage device is similar to
Window XP and filename can recognize up to 25 European
characters.
• Please backup important files because data on USB device may
be damaged. Data management is consumer’s responsibility and
as a result, the manufacturer does not cover data damage.

5-1) Update using RS-232C cable.
5-1-1) Preparation.
① TV Set.
② Update Cable (RS-232C Cable).
③ IBM Compatible PC.
5-1-2) System Configuration.
PC Configuration.
All the configuration of Serial Port (COM1/COM2) should be done before proceed because the update requires
RS-232C port of PC.
11
Be sure Communication Port is installed
properly as seen on the figure.
If Communication (Serial) Port is not installed, check your CMOS (Computer System Menu) and activate Serial
Port in it.
5-1-3) Introduction.
A PC tool “Serial Flasher” is provided to update Magello software.
The PC tool must be started before starting up the board.
Page 12
12
5-1-4) Tool installation.
Uncompress the zip file provided in a working directory.
In this directory copy also the binary file (magello.bin) which will be used for the software update.
5-1-5) Procedure.
① Main power off the board.
② Connect a serial cable(RS-232C) between the board and the PC where the “Serial Flasher” is installed.
③ Check the new “magello.bin” is in the “Serial Flasher” directory.
④ Start the PC Tool : LW Serial Flasher_Daewoo_IDTV.exe.
< Main screen of Serial flasher>
⑤ Use browse button “…” to select the new software for the upgrade (magello.bin).
<Serial flasher : New software selected>
⑥ Press “GO!” to start the connection process.
⑦ Power on the board.
⑧ Wait a few seconds for the connection process to start : The message : « Connecting board … » is displayed.
Page 13
First of all, power of board should be turned on, as a normal operating mode, during update.
If error message is displayed, after turn off main power, check above ②. And then repeat from ① to ⑦.

A. Check RC470.
: RC470 is only one path from main chip(IC401) to SMPS. During power on, both sides of RC470 should be
high. If it is high and back light of LCD does not turn on, check as ‘Check followings’. If cables are no problem,
finally check SMPS. (see the page 36)
B. Check RC469
: RC469 is located between main chip(IC401) and transistor(QC701) for switch LCD panel power. During power
on, both sides of RC469 should be high. If it is high and LCD power is low, check as ‘Check followings’. If
QC701, QC702, LC701 are no problem, check LCD panel.
C. Details of Check followings.
-. QC701 : Transistor for switching LCD panel power.
-. QC702 : FET for driving LCD panel power.
-. LC701 : Coil for rectifying LCD panel power.

Clock length should be 400mils longer than Addresses and controls signal
lengths.
Address trace length should be equalized.
DDRII LENGTH = DQS+CLK
Signals should be routed with no right angle, only 45 degrees turn with
smooth edges.
