IMPORTANT SERVICE SAFETY PRECAUTION
Service work should be performed only by qualified service
technicians who are thoroughly familiar with all safety checks and
the servicing guidelines which follow: Use an AC voltmeter having
with 5000 ohm per volt, or higher, sensitivity or measure the AC
voltage drop across the resistor. Connect the resistor connection
to all exposed metal parts having a return to the chassis (antenna,
metal cabinet, screw heads, knobs and control shafts, escutcheon,
etc.) and measure the AC voltage drop across the resistor. All
checks must be repeated with the AC cord plug connection reversed.
(If necessary, a nonpolarized adaptor plug must be used only for
the purpose of completing these checks.) Any reading of 0.75 Vrms
(this corresponds to 0.5 mA rms AC.) or more is excessive and
indicates a potential shock hazard which must be corrected before
returning the monitor to the owner.
WARNING1. For continued safety, no modification of any circuit
should be attempted. 2. Disconnect AC power before servicing.
CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE
ONLY WITH SAME TYPE FUSE.

Shock Hazard)Before returning the receiver to the user, perform the
following safety checks: 1. Inspect all lead dress to make certain
that leads are not pinched, and check that hardware is not lodged
between the chassis and other metal parts in the receiver. 2.
Inspect all protective devices such as non-metallic control knobs,
insulation materials, cabinet backs, adjustment and compartment
covers or shields, isolation resistor-capacitor networks,
mechanical insulators, etc. 3. To be sure that no shock hazard
exists, check for leakage current in the following manner. Plug the
AC cord directly into a 120 volt AC outlet. Using two clip leads,
connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15F
capacitor in series with all exposed metal cabinet parts and a
known earth ground, such as electrical conduit or electrical ground
connected to an earth ground.

Many electrical and mechanical parts in LCD color television
have special safety-related characteristics. These characteristics
are often not evident from visual inspection, nor can protection
afforded by them be necessarily increased by using replacement
components rated for higher voltage, wattage, etc. Replacement
parts which have these special safety characteristics are
identified in this manual; electrical components having such
features are identified by "
" and shaded areas in the Replacement Parts List and Schematic
Diagrams. For continued protection, replacement parts must be
identical to those used in the original circuit. The use of a
substitute replacement parts which do not have the same safety
characteristics as the factory recommended replacement parts shown
in this service manual, may create shock, fire or other
hazards.

Precautions for using lead-free solder1 Employing lead-free
solder "PWBs" of this model employs lead-free solder. The LF symbol
indicates lead-free solder, and is attached on the PWBs and service
manuals. The alphabetical character following LF shows the type of
lead-free solder. Example:
LFaIndicates lead-free solder of tin, silver and copper.
L F a/aIndicates lead-free solder of tin, silver and copper.
2 Using lead-free wire solder When fixing the PWB soldered with
the lead-free solder, apply lead-free wire solder. Repairing with
conventional lead wire solder may cause damage or accident due to
cracks. As the melting point of lead-free solder (Sn-Ag-Cu) is
higher than the lead wire solder by 40C, we recommend you to use a
dedicated soldering bit, if you are not familiar with how to obtain
lead-free wire solder or soldering bit, contact our service station
or service branch in your area. 3 Soldering As the melting point of
lead-free solder (Sn-Ag-Cu) is about 220C which is higher than the
conventional lead solder by 40C, and as it has poor solder
wettability, you may be apt to keep the soldering bit in contact
with the PWB for extended period of time. However, Since the land
may be peeled off or the maximum heat-resistance temperature of
parts may be exceeded, remove the bit from the PWB as soon as you
confirm the steady soldering condition. Lead-free solder contains
more tin, and the end of the soldering bit may be easily corroded.
Make sure to turn on and off the power of the bit as required. If a
different type of solder stays on the tip of the soldering bit, it
is alloyed with lead-free solder. Clean the bit after every use of
it. When the tip of the soldering bit is blackened during use, file
it with steel wool or fine sandpaper.
Be careful when replacing parts with polarity indication on the
PWB silk. Lead-free wire solder for servicing Part No, Description

Unit: DUNTKD643FM06 (LC-37D40U) / DUNTKD643FM07 (LC-45D40U)
2. Upgrading of each microprocessor softwareCaution: Never
"POWER OFF" the unit when software upgrade is ongoing. Otherwise
the system may be damaged beyond recovery.
2-1. Software version upgradeThe model employs the following
software. Main software Monitor microprocessor software The main
software and the monitor microprocessor software can be upgraded by
using a general-purpose SD memory card. The followings are the
procedures for upgrading, explained separately for each of the main
software, the monitor microprocessor software.
2-2 Main software version upgradeGet ready before you start SD
memory card of 32MB or higher capacity PC running on Windows
98/98SE/ME/2000/XP operating system SD memory card reader/writer
with USB connectivity. SD memory card formatting software
(Downloadable at
http://panasonic.jp/support/audio/sd/download/sd_formatter_e.html)

LC-37D40U LC-45D40U
Preparations To upgrade the main software, it is necessary to
get ready the SD card for version upgrade before you start. Follow
the steps below and create the SD card for version upgrade. 1
Insert the SD card into the SD card reader/writer. Start the SD
card formatting software. Click [Format]. (When you have the drive
options, select the drive where the SD card is inserted before you
proceed.)
2 When the formatting is over, the following window appears.
Click [OK].
3 Click [Exit] to finish the formatting. Note: When you are
done, take out the SD card once to make sure it is finished, and
then insert it again.
4 Copy the binary image file M150Axxx.SDC (named temporarily)
for version updade to the root directory (folder) of the SD card
drive. Note: In the SD card drive, do not store other folders or
unrelated files, or more than one binary image files for version
upgrade. Now the SD card for version upgrade is ready.

LC-37D40U LC-45D40U
How to upgrade the software 1 Shut off the AC power (i.e. unplug
the AC cord). 2 Insert the SD card for version upgrade (prepared as
above) into the service socket located lower side from center at
terminals, above S-VIDEO terminal in the rear of the unit, in a way
that the cut corner of the SD card comes at the upper side. Note:
If the SD card is inserted in a wrong way, the card will go deep
inside the unit beyond retrieval. Take due care to insert the SD
card correctly. 3 Turn on the AC power (i.e. plug in the AC cord).
4 After the unit startup, the system upgrade screen as shown below
appears within 20-40 seconds.

monitor microprocessor software version upgrade in the same manner
as explained in the "Main software version upgrade". Copy the
binary image file M150Mxxx.SDC (named temporarily) for monitor
microprocessor software version upgrade to the SD card drive. How
to upgrade the software 1 Shut off the AC power to the unit (i.e.
unplug the AC cord). 2 Insert the SD card for version upgrade
(prepared as above) into the service socket located lower side from
center at terminals, above S-VIDEO terminal in the rear of the
unit, in a way that the cut corner of the SD card comes at the
upper side. Note: If the SD card is inserted in a wrong way, the
card will go deep inside the unit beyond retrieval. Take due care
to insert the SD card correctly. 3 Turn on the AC power (i.e. plug
in the AC cord). Caution!! The moment this operation is done, the
upgrading of the monitor microprocessor software starts. While the
upgrade is ongoing, never power off the unit. Otherwise the upgrade
will fail and the system may have a serious damage beyond recovery
(inability to start). 4 After the unit startup, the system upgrade
screen as shown below appears within 10-30 seconds.

MAJOR IC INFORMATIONS IC8101
(RH-IXB145WJQZQ) An LSI of a MPEG-2 system decoder that performs
back-end processing for digital broadcasting. This is equipped with
a CPU (processor core: AM33-3), descrambler (DES), transport stream
demultiplexer, video decoder (MPEG-2 MP@HL compatible), graphic
processor, audio decoder (AC3 compatible), and an NTSC video
encoder. After receiving transport stream from the tuner, the LSI
decrypts pay-TV broadcasts with the descrambler. Then using the
demultiplexer, it separates and decodes the compressed audio and
video data to send the signals. In the visual system, the graphic
processor makes it possible to overlap subtitles and perform
scaling. Digital video signals (Y, Pb and Pr, or 480I/P, 720P and
1081I) and downconverted NTSC signals (Y/C and composite, or 480I)
can be sent simultaneously. As for the audio system, decoded AC3
audio can be overlapped with sound effects. The LSI also contains
various interfaces (I2C x 2, UART x 3, an SD Memory Card interface,
a CableCARD interface, etc.) and a GPIO. Using these interfaces,
the CPU controls peripheral circuits of the tuner, SD Memory Cards,
CableCARDs, etc. One of the UARTs is used by the CPU to establish
communications with the monitor microcomputer in the unit, where
remote control information or other data is exchanged. Another UART
is used for RS-232C serial communications to connect the unit to a
PC.
