SAFETY PRECAUTION
IMPORTANT SERVICE SAFETY PRECAUTION
WARNING
1. For continued safety, no modification of any circuit should be
attempted.
2. Disconnect AC power before servicing.
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 220~240 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.
• 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 1.05 V peak (this corresponds to 0.7 mA peak AC.)
or more is excessive and indicates a potential shock hazard which
must be corrected before returning the monitor to the owner.
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.
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the
servicing guidelines which follow:
CAUTION:
FOR CONTINUED PROTECTION AGAINST A
RISK OF FIRE REPLACE ONLY WITH SAME
TYPE FUSE.

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:
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.
Indicates lead-free solder of tin, silver and copper.
L F a/a
Indicates lead-free solder of tin, silver and copper.

The TV sometimes makes a cracking
sound.
This is not a malfunction. This happens when the cabinet slightly expands and contracts
according to changes in temperature. This does not affect the TV’s performance.
Cautions regarding use in high and low temperature environments
When the TV is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed.
This is not a malfunction, and the TV will recover when the temperature returns to normal.
Do not leave the TV in a hot or cold location. Also, do not leave the TV in a location exposed to direct sunlight or near a
heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
Storage temperature: +5 °C to +35 °C.

7. Lamp error detection
1. Function
This LCD color TV set incorporates a lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp
circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason, the following will result.
1) The power is interrupted in about 6 seconds after it is turned on.
(The power LED on the front of the TV set turns red from green and keeps blinking in red: ON for 300ms and OFF for 1500ms.).
2) If the above phenomenon 1) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).
2. Measures
1) Checking with lamp error detection OFF
Enter the adjustment process mode, referring to 2. Entering and exiting the adjustment process mode.
If there is a problem with the lamp or lamp circuit, the lamp will go out. (The power LED is green.)
Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
2) Resetting the lamp error count
After the lamp and lamp circuit are found out of trouble, reset the lamp error count. If a lamp error is detected five consecutive times, the power
cannot be turned on. Using the cursor (/) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/16. With the cursor (</>) keys, select the [LAMP ERROR RESET] value. Finally press the cursor (OK) eys to reset the value to “0”.

[2] LED flashing specification at the time of the error
Display method
• Refer to Table 1.
• Make the OPC LED flash using the [MENU] key on the remote control since the display for service persons is identified by the number of flashings
(once to 5 times).
Even if the [MENU] key is pressed again, it does not return to the display for customers (only the power LED flashes).
• After recovering from an error, if the same error cannot be generated again, refer to MONITOR ERR CAUSE on the adjustment process screen.
LED flashing method
• Synchronize the phases of the power LED and OPC LED.
• If the LEDs have different number of flashings, adjust the flashing cycle to that where the LED flashes more times.

Error typeOPC (preset) LED operation (1 cycle)Note: Pins are monitor microprocessor pins unless otherwise specified (IC2003).
Lamp failure
Flashes once
H: OnERR_PNL (40pin): Abnormal L. Confirmed after 5 consecutive detections at 1 second
intervals (detected only when the backlight is on).
Note that after five detection counts, the lamp cannot be activated except in the monitoring process. (For the first time, only the inverter is reset, and error OFF is not activated.)
Accumulated counts are cleared to 0 when the setting in the adjustment process is
made, when AC_ON is performed with [CH_DOWN] and [VOL_UP] on the unit down
or after continuous illumination for 3 minutes.
L: Off
Error typeOPC (preset) LED operation (1 cycle)Note: Pins are monitor microprocessor pins unless otherwise specified (IC2003).
PS_ON
AC_DET failure Flashes
once
H: OnAC_DET (72pin: Abnormal (L).
If error is detected during start-up or operation, the power is turned on again by interrupt handling (instantaneous blackout processing).
L: Off
D_POW
Main 12V failure Flashes
twice
H: OnDET_12V (34pin): Abnormal (L). Main 12V is not applied.
L: OffIf error is detected during start-up or operation, the power is turned on again by polling.
D_POW
Digital 3.3V
Failure
Flashes 3
times
H: OnDET_D3V3 (35pin): abnormal (L). Digital 3.3V is not applied.
L: OffIf error is detected during start-up or operation, the power is turned on again by polling.
Error typeOPC (preset) LED operation (1 cycle)Note: Basically, debug print logs are analyzed or communication logs
are analyzed by a bus monitor.
Initial communication reception
failure Flashes
once
H: OnInitial communication from the main CPU is not received. (Request for the
monitor model No. is not received.)
→ Communication line failure or main CPU start-up failure
H: OnStart-up reason confirmation from the main CPU cannot be received. (Start-
up communication until start-up reason notification command is not
received.)
→ Main CPU start-up failure or monitor microprocessor reception failure
L: Off
Regular communication failure
Flashes 3 times
H: OnRegular communication that is performed at 1 second intervals in the nor-
mal operation is interrupted.
→ Main CPU operation failure or monitor microprocessor reception failure
L: Off
Other communication failure
Flashes 5 times
H: OnWhen a request (PM_REQ=H) is sent from the main microprocessor, the
request command is not output from the main CPU, etc.
→ Main CPU operation failure or monitor microprocessor reception failure
L: Off
Error typeOPC (preset) LED operation (1 cycle)Note: Pins are monitor microprocessor pins unless otherwise specified
(IC2003).
Monitor temperature failure
Flashes once
H: OnIf the panel temperature is 60°C or more for 15 seconds or more in a row, CAUTION
appears on the OSD (flashes in red in the lower right screen).
If the panel temperature is 60°C or more for 25 seconds or more in a row, error
standby is activated.
(MONITOR MAX TEMP on page 13/16 of the adjustment process: Change of temperature failure AD value): Thermistor

CHAPTER 7. SCHEMATIC DIAGRAM
[1] DESCRIPTION OF SCHEMATIC DIAGRAM
VOLTAGE MEASUREMENT CONDITION:
1. The voltages at test points are measured on exclusive AC adaptor and the stable supply voltage of AC 230V.
Signals are fed by a colour bar signal generator for servicing purpose and the above voltages are measured with a 20k ohm/V tester.
INDICATION OF RESISTOR & CAPACITOR:
RESISTOR
1. The unit of resistance “Ω” is omitted.
(K=kΩ=1000 Ω, 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.
IMPORTANT SAFETY NOTICE:
PARTS MARKED WITH “ ” () ARE
IMPORTANT FOR MAINTAINING THE SAFETY OF THE
SET. BE SURE TO REPLACE THESE PARTS WITH
SPECIFIED ONES FOR MAINTAINING THE SAFETY AND
PERFORMANCE OF THE SET.
