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:
WARNING
1. For continued safety, no modification of any circuit should be
attempted.
2. Disconnect AC power before servicing.
CAUTION: FOR CON T I NUED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE.
F0001 (250V 15A)
F0003 (250V 1.6A)
• 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.

BEFORE RETURNING THE RECEIVER (Fire & Shock Hazard)
Before returning the receiver to the user, perform the following
safety checks:
3. 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.
4. 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.
5. To be sure that no shock hazard exists, check for leakage current in
the following manner.
• Plug the AC cord directly into a 110-240 volt AC outlet.
• Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15µF 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.

SAFETY NOTICE
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 SOLDER
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:
Indicates lead-free solder of tin, silver and copper. Indicates lead-free solder of tin, silver and copper.
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 40 °C, 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.
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40 °C, 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.

• When replacing the following units, make sure to prepare the new units loaded with updated software.
MAIN Unit: DUNTKE207FM01
2. Upgrading of each microprocessor software
CAUTION: Never “POWER OFF” the unit when software upgrade is ongoing.
Otherwise the system may be damaged beyond recovery.
2.1. Software version upgrade
The 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 USB Memory.
The followings are the procedures for upgrading, explained separately for the main software, and the monitor microprocessor software.
2.2. Main software version upgrade
2.2.1 Get ready before you start
• USB Memory of 128MB or higher capacity.
• PC running on Windows 98/98SE/ME/2000/XP operating system.
• USB Memory reader/writer or PC with a USB port.
• The file system of a USB memory is FAT. (FAT32 is not applied)
• Use the USB memory without other functions. (lock and memory reader...etc)
2.2.2 Preparations
To upgrade the main software, it is necessary to get ready the USB Memory for version upgrade before you start.
Follow the steps below and create the USB Memory for version upgrade.
1. Copy the file D64UAxxx.USB (named temporarily) for version upgrade to the root directory (folder) of the USB Memory.
NOTE: In the USB Memory drive, do not store other folders or unrelated files, or more than one file for version upgrade.
Now the USB Memory for version upgrade is ready.
2.2.3 How to upgrade the software
1. Unplug the AC cord.
2. Insert the USB Memory for version upgrade (prepared as above) into the service socket located Right side from center at terminals, above HDMI4
terminal in the rear of the unit.
3. Plug in the AC cord with power button pressed down after 5 seconds, unpress the power button.
4. After the unit startup, the system upgrade screen as shown below appears within 20-40 seconds.
5 – 1

5. Even a single failure in the process will trigger the upgrade failure screen.
UPGRADE FAILURE
NOTE: In the event of a failure, repeat the upgrade process. If the process repeatedly fails, it is likely that the hardware need fixing.
6. Upon completion of the whole process, the upgrade success screen as shown below appears. You can check the new software version on this
screen. The version information appears after the upgrade is complete.
UPGRADE SUCCESS
7. Unplug the AC cord and remove the USB Memory for version upgrade.

power off the unit. Otherwise the upgrade will fail and the system may be serious damaged beyond recovery (inability to start).
• After the monitor microprocessor software is upgraded, also perform the 'Industry Init'.
6. If the upgrade fails, power led will stop blinking. Also, the upgrade failure screen will be shown if upgrade screen was shown at 5.
UPGRADE FAILURE
NOTE: In the event of a transient failure, upgrade will be automatically retried up to three times. If the process repeatedly fails, hardware may be the
cause.
7. Up on completion of the whole process, power and OPC LED will blink alternately. Also, the upgrade success screen will be shown if upgrade
screen was shown at 5.
UPGRADE SUCCESS
8. Unplug the AC cord and remove the USB Memory for version upgrade.
9. Now the software version upgrade is complete.

8.2. Adjusting procedure by use of [RS-232C]
1. Get ready the PC with COM port (RS-232C) running on Windows 95/98/ME/2000/XP operating system, as well as the RS-232C cross cable.
2. Start the unit with the RS-232C cable connected.
3. Start the terminal software. (The freeware readily available on the Internet will do.)
4. Make the following settings.
Baud rate 9,600 bps
Data LENGTH 8 bit
Parity bit None
Stop bit 1 bit
Flow control None
5. If the settings are correct, the terminal software indicates “ERR” against pressing of the “ENTER” key.
6. After the settings are done correctly, it is possible to make an adjustment by typing in the command shown in the table below and pressing the
“ENTER” key on the keyboard.
7. Command entry is successful if the terminal software indicates “OK” when the “ENTER” is pressed. If “ERR” is shown, retry to enter the command.
8. Send the process mode switching command to switch from the RS232C operation mode to the process mode.
KRSW0001: “ERR” is returned.
KKT10037: When “OK” is returned, the process mode becomes active. When “ERR”, start over from KRSW0001.
9. Send each adjustment command.
9. Initialization to factory settings
CAUTION: When initialization is performed, all user setting data including the channel settings are initialized. Be cautious when making this adjust-
ment.
(The adjustments done in the adjustment process mode are not initialized.)
Adjustment item Adjustment conditions Adjustment procedure
1 Initialization It turns off with AC power
supply.
After the adjustment, cancel the adjustment process mode.
To exit the adjustment process mode, unplug the AC power cable from the outlet to make a
forced shutdown. (When the power was turned off with the remote controller, once unplug the
power cable and plug it again. In this case, wait 10 seconds or so before plugging.)
Enter the adjustment process mode.
Bring the cursor on to [INDUSTRY INIT] in page 2/32.
Set to [ON] using [VOL] key, and press [ENTER] to execute the initialization.
When the version number screen shows up on the green background and “SUCCESS”
gets displayed at the top on screen, it means the procedure has been successfully carried out.
(If an error occurs, “ERROR” is displayed on the red background.)
•Turn off the AC power.
*Never shut off the power during the initialization process.
The following settings are initialized in this adjustment.
1) User setting
2) Channel data (e.g. broadcast frequencies)
3) Password data
4) Operation time
5) Auto installation flag
6) V-CHIP block setting

[1] DESCRIPTION OF SCHEMATIC DIAGRAM
1. VOLTAGE MEASUREMENT CONDITION:
1) The voltages at test points are measured on exclusive AC adaptor and the stable supply voltage of AC 120V. Signals are fed by a color bar signal
generator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.
2. INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1) The unit of resistance "Ω" is omitted.
(K=kΩ=1000Ω, M=MΩ).
2) All resistors are ± 5%, unless otherwise noted.
(K= ± 10%, F= ± 1%, D= ± 0.5%)
3) All resistors are 1/16W, unless otherwise noted.
CAPACITOR
1) All capacitors are µF, unless otherwise noted.
(P=pF=µµF).
2) All capacitors are 50V, unless otherwise noted.
CAUTION:
This circuit diagram is original one, therefore there may be a slight
difference from yours.
SAFETY NOTES:
1) DISCONNECT THE AC PLUG FROM THE AC OUTLET
BEFORE REPLACING PARTS.
2) SEMICONDUCTOR HEAT SINKS SHOULD BE REGARDED AS
POTENTIAL SHOCK HAZARDS WHEN THE CHASSIS IS
OPERATING.
