SAFETY PRECAUTION
Service Manual
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 CONTINUED PROTECTION AGAINST A
RISK OF FIRE REPLACE ONLY WITH SAME
TYPE FUSE.
• 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.
FS1 (2.5A/250V)
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.
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:
L Fa
Indicates lead-free solder of tin, silver and copper.
Indicates lead-free solder of tin, silver and copper.
L F a/a
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.

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 250 ms and OFF for 1 sec).
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 “3. 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.
Using the (UP/DOWN) key, move to the cursor to "ERROR NO RESET", line 3 on adjustment process mode service page 1.
With the (LEFT/RIGHT) keys, select the "ERROR NO RESET" value.
Finally press the (OK) keys to reset the value to "0".

Internal clock signals are derived from CK/CK
buffers and output drivers.
Taking CKE Low provides PRECHARGE POWER DOWN and SELF REFRESH operction(all bank idle)
CKE is synchronous for POWER-DOWN entry and exit, and for SELF REFRESH entry.
CKE is asynchronous for SELF REFRESH exit, and for output disable.
CKE must be maintained high throughput READ and WRITE accesses.
Input buffers, excluding CK,CK
Input buffers, excluding CKE are disabled during SELF REFRESH.
CKE is an SSTL_2 input, but will detect an LVCMOS Low level after Vdd is applied upon 1st power up,
After VREF has become stable during the power on and initialization sequence, it must be maintained
for proper operation of the CKE receiver.
For proper SELF-REFRESH entry and exit, VREF must be maintained to this input.
IChip Select : CS enables(registered LOW) and disables(registered HIGH) the command decoder.
All commands are masked when CS is registered HIGH.
CS
provides for external bank selection on systems with multiple banks.
CS
is considered part of the command code.
Input data is masked when DM is sampled HIGH along with that input data during a WRITE access.
DM is sampled on both edges of DQS.
Although DM pins are input only, the DM loading matches the DQ and DQS loading.
For the x16, LDM corresponds to the data on DQ0~D7 ; UDM corresponds to the data on DQ8~DQ15.
DM may be driven high, low, or floating during READs.

and CKE are disabled during POWER-DOWN.

NC-No Connect : No internal electrical connection is present.
PRECHARGE bit for READ/WRITE commands, to select one location out of the memory array in the
respective bank.
A10 is sampled during a PRECHARGE command to determine whether the PRECHARGE applies to
one bank (A10 LOW) or all banks (A10 HIGH).
If only one bank is to be precharged, the bank is selected by BA0, BA1.
The address inputs also provide the op-code during a MODE REGISTER SET command.
BA0 and BA1 define which mode register is loaded during the MODE REGISTER SET command (MRS
or EMRS).
Edge-aligned with read data,centered in write data.
Used to capture write data.
