IMPORTANT SERVICE SAFETY PRECAUTION
Ë
Service work should be perfomed 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 ONL Y WITH SAME
TYPE F3701 (1.6A, 250V),
F3702(1.6A, 250V), F6500 (1.25A,
A V
250V) AND F6510 (1.25A, 250V)
FUSE.
BEFORE RETURNING THE RECEIVER
(Fire & 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 110~240 volt AC outlet,
and connect the DC power cable into the receiver's
DC jack. (Do not use an isolation transformer for this
test).
• Using two clip leads, connect a 50k 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 resisor.
• 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 0.75V peak (this corresponds to 0.5
milliamp. 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 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 “ å”
234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121
and shaded areas in the Replacement Parts Lists 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
1 Employing lead-free solder
"All 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.
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 40ºC, we recommend
you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldening
bit, contact our service station or service ranch in your area.
3 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 wettabillty , 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 excoeded, remove the bit from the PWB as soon as you conurm the steady soldering
condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to tum 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.
Becareful when replacing parts with polarity indication on the PWB silk.

ADJUSTING PROCEDURE OF EACH SECTION
Preparation for Adjustments
Use the dedicated AC adaptor or stable DC power supply.
AC adaptor: UADP-A021WJPZ
DC power supply: 12 ± 0.5V, 4.0 (A)
[1] Adjusting procedure
1-1. Checker adjustment
Power ON (initialization) → Setting of model and inch size → Model data transfer to the setting E2PROM (I2C)
→ Adjustment processing mode → Adjustment (+B adjustment)
1-2. Finish processing adjustment
Setup → Power ON → Adjustment processing mode (Remote control) → Counter bias, TV contrast and white
balance adjustments
[2] Entering the adjustment processing mode
There are the following two methods.
• Setting the pin (81) (KEY4) or pin (82) (KEY5) of IC2001 (microprocessor) to "L", turn on the power.
• When service is given: POWER button is made on with pushing TV/VIDEO and MENU buttons at the same
time.(K of the inspection process mode is displayed by the upper left of the image plane.) → Next, CH (Ù) and
VOL (–) buttons are pushed at the same time.(It becomes the image plane of the adjustment process
mode.).....When it is canceled, it is made to turn it off.(Even off in the POWER button, off with R/C are good.)
[3] Key operation in the adjustment processing
Selection of the receiving channel
• The receiving channel UP/DOWN is performed with the CH (ù)/(Ù) buttons.
One push ... The UP/DOWN tuning is performed per channel.
Continuous push ... The UP/DOWN search is performed until a next receivable station is found.
• Various adjustments
The adjustment is performed for each item by the MENU, VOL (+)/(–) buttons (main body and remote control).
• Adjustment item is chosen with the MENU cursor UP/DOWN buttons.
• The adjustment item makes a toggle operation with the MENU button input. (Next item)
If the MENU button is input while the bottom item is selected, it moves to the top item on the next page.
[4] Initialization
4-1. Connect the pins (81) and (82) of IC2001 (microprocessor) to GND, and turn on the power.
4-2. Select the model name (E1H).
4-3. Select the inch size (13):LC-13E1H/M and (15):LC-15E1H/M.

[5] Adjustment
5-1. +B adjustment...R3760 and a half fixations VOL
1) Receive the colour bar signal.
2) Adjust the voltage of the pin (2) of P3702 to 5.00±0.02V.
Note: Since 5.0V is a reference voltage of all power voltage, adjust it precisely.
5-2. Counter-bias adjustment...Page 2 COM BIAS
Vary the "COM BIAS" setting on Page 2 of the adjustment process so that the contrast be sharpest (black looks
most sinking). The adjustment guideline is around "115" for models LC-13E1H/M and "113" for models LC15E1H/M.
5-3. TAMP adjustment
1) Receive the colour bar signal.
2) When reading value of adjustment process the page 2 "Y" is not within value of the bottom table, the adjustment
of "NTSC TAMP" of the same page is done, and reading value of "Y" is made to be within value of "BF" to
"C9".
3) If the adjustment of "NTSC TAMP" is executed, write its adjustment value to the followings manually.

1) Receive the monoscope pattern signal.
2) Adjust "RCUT OFF" and "BCUTOFF" on the page 2 of the adjustment processing so as to obtain the colour of
the same level as the standard set.
Caution: For the adjustment processing of "RCUTOFF" and "BCUTOFF", adjust them in the indication value
range of ... –9, –7, ... –1, +1, ... +7, +9.
When it becomes even-numbered value, side favor noise sometimes occurs in the monochrome signal of the
specific gradation.

[6] Lamp error detection
6-1. Functional description
This LCD colour television has a function (lamp error detection) to be turned OFF automatically for safety
when the lamp or lamp circuit is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed,
the followings occur.
1 The main unit of television is turned OFF 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 , television can not be turned ON. (The power LED remains
red.)
6-2. Countermeasures
6-2-1. Check when turning OFF the lamp error detection
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 "ERROR NO RESET" on line 8, page 1 of the adjustment process is 1 or more. If it is 1 or
more, it indicates the lamp error detection was executed.
6-2-2. Resetting of the lamp error count
After confirming that the lamp or lamp circuit is normal, reset the lamp error count. Select "ERROR NO
RESET" on line 8, page 1 of the adjustment process and set the number to 0 using the volume button.
