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.
LC-32LE600E/RU/S: F7001, F7002 (2.5A/250V)
LC-40LE600E/RU/S: F7001, F7002 (5A/250V)
LC-46LE600E/RU/S: F7001, F7002 (6.3A/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.
• 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.

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.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
TO EXPOSED METAL PARTS
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.

2. ERROR STANDBY CAUSE When main CPU becomes a power-off detecting some abnormalities, the use time of the set at the time of the reason and the power-off is dis-
played five times. When time information can be acquired from digital broadcasting, the date and time when the error occurs at the same time is recorded, displayed
and when time information cannot be acquired, it becomes the above-mentioned display. “00” is displayed when abnormality has not been detected even once.
Display error code Display character string Reason
0x1A 1a TEMP_ERROR When temperature (high temperature) is abnormal. 0x1B 1b LAMP_ERROR When lamp is abnormal

14. Lamp error detection
1. Function description This LCD colour television has a function (lamp error detection) to be turned OFF autom atically for safety wh en the lamp or lam p circuit is abnor-
mal. If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed, the following occur.
1) The main unit of television is turned OFF about 5 seconds after it is turned ON.
(The power LED on the front side of TV turns from green to red.)
2) If the situation “1” happens 5 times sequentially, the power is turned on (relay is turned ON).
However, the backlight is not turned on, and then the relay is turned OFF after 5 to 6 seconds. (The power LED remains red.)
2. Countermeasures When television is turned OFF by the lamp error detection mentioned above, it enters the adjustment process with the power LED red. Entering the adjustment process, turns OFF the error detection and turns ON TV. This enables the operation check to detect errors in the lamp or lamp circuit. Check whether “STANDBY CAUSE” on line 7, page 1/8 of the adjustment process is “1B”. it indicates the lamp error detection was executed. After confirming that the lamp or lamp circuit is normal, reset the lamp error counter pushing “OK” in the R/C. After resetting counter the green bar appears on Screen.
3. Reset standby cause error list After confirming that the lamp error counter has been erased, select “ERROR RESET”, page 1/8 of the adjustment process and select YES using
the right cursor. For execute press “OK” in the R/C and the label “***OK***” appears on Screen.

L8 CS# I Chip Select:
CK and CK# are differential clock inputs. All address and control input signals are sampled on the crossing of the positive edge of CK and negative edge of CK#. Output (read) data is referenced to the crossings of CK and CK# (both directions of crossing).
CKE HIGH activates, and CKE Low deactivates, internal clock signals and device input buffers and output drivers. Taking CKE Low provides Pre charge Power-Down and Self Refresh operation (all bank idle), or Active Power-Down (row Active in any bank). CKE is synchronous for power down entry and exit, and for self refresh entry. CKE is asynchro­nous for self refresh exit. 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. CKE must be maintained high throughout read and write accesses. Input buffers, excluding CK, CK#, ODT and CKE are disabled during power-down. Input buffers, excluding CKE are disabled during self refresh.
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.

ODT (registered HIGH) enables termination resistance internal to the DDR2 SDRAM. When enabled, ODT is only applied to each DQ, DQS, DQS#, RDQS, RDQS#, and DM signal for x4/x8 configuration. For x16 configuration, ODT is applied to each DQ, UDQS/UDQS#. LDQS/LDQS#, UDM and LDM signal. The ODT pin will be ignored if the Extended Mode Register Set (EMRS) is programmed to disable ODT.
I Command Inputs:
RAS#, CAS# and WE# (along with CS#) define the command being entered.
I Input Data Mask:
DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH coinci­dent 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 x8 device, the function of DM or RDQS/RDQS# is enabled by EMRS command.
BA0 and BA1 define to which bank an Active, Read, Write or Pre charge command is being applied. Bank address also determines if the mode register or extended mode register is to be accessed during a MRS or EMRS cycle.
Pre charge bit for Read/Write commands to select one location out of the memory array in the respective bank. A10 is sampled during a pre charge command to determine whether the PRECHARGE applies to one bank (A10 LOW) or all banks (A10 HIGH). If only one bank is to be pre charged, the bank is selected by BA0, BA1. The address inputs also provide the op-code during a Mode Register Set command.
I/O Data Input/Output: Bi-directional data bus.
I/O Data Strobe:
Output with read data, input with write data. Edge-aligned with read data, centered in write data. For the x16, DQS1 corresponds to the data on DQ0>DQ7; DQS0 corresponds to the data on DQ8>DQ15. For the x8, an DQS2 option using DM pin can be enabled via the EMRS (1) to simply read timing. The data strobes DQS1, DQS0, DQS3, and DQS2 may be used in single ended mode or paired with optional complementary signals DQS1#, DQS0#, DQS3# and DQS2# to provide differential pair signaling to the system during both reads and writes.

CHAPTER 9. SCHEMATIC DIAGRAM
[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 220-240V. 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 "" is omitted. (K=k=1000, M=M).
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.
