IMPORTANT SAFETY PRECAUTIONS

Prior to shipment from the factory, our products are strictly inspected for recognized product safety and electrical
codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally
important to implement the following precautions when a set is being serviced.

Safety Precautions for LCD TV
Circuit

1. Before returning an instrument to the

customer, always make a safety check of the

entire instrument, including, but not limited to, the
following items:

a. Be sure that no built-in protective devices are

defective and have been defeated during
servicing. (1) Protective shields are provided
on this chassis to protect both the technician
and the customer. Correctly replace all missing
protective shields, including any removed for
servicing convenience. (2) When reinstalling
the chassis and/or other assembly in the
cabinet, be sure to put back in place all
protective devices, including but not limited to,
nonmetallic control knobs, insulating
fishpapers, adjustment and compartment
covers/shields, and isolation resistor/capacitor
networks. Do not operate this instrument or

permit it to be operated without all
protective devices correctly installed and
functioning. Servicers who defeat safety
features or fail to perform safety checks
may be liable for any resulting damage.

b. Be sure that there are no cabinet openings

through which an adult or child might be able to
insert their fingers and contact a hazardous
voltage. Such openings include, but are not
limited to, (1) spacing between the Liquid
Crystal Panel and the cabinet mask, (2)
excessively wide cabinet ventilation slots, and
(3) an improperly fitted and/or incorrectly
secured cabinet back cover.

c. Antenna Cold Check - With the instrument AC

plug removed from any AC source, connect an
electrical jumper across the two AC plug
prongs. Place the instrument AC switch in the
on position. Connect one lead of an ohmmeter
to the AC plug prongs tied together and touch
the other ohmmeter lead in turn to each tuner
antenna input exposed terminal screw and, if
applicable, to the coaxial connector. If the
measured resistance is less than 1.0 megohm
or greater than 5.2 megohm, an abnormality
exists that must be corrected before the
instrument is returned to the customer. Repeat
this test with the instrument AC switch in the off
position.

d. Leakage Current Hot Check - With the

instrument completely reassembled, plug the
AC line cord directly into a 120 V AC outlet. (Do
not use an isolation transformer during this
test.) Use a leakage current tester or a
metering system that complies with American
National Standards Institute (ANSI) C101.1
Leakage Current for Appliances and
Underwriters Laboratories (UL) 1410, (50.7).
With the instrument AC switch first in the on
position and then in the off position, measure
from a known earth ground (metal water pipe,
conduit, etc.) to all exposed metal parts of the
instrument (antennas, handle brackets, metal
cabinet, screw heads, metallic overlays, control
shafts, etc.), especially any exposed metal
parts that offer an electrical return path to the
chassis. Any current measured must not
exceed 0.5 milli-ampere. Reverse the
instrument power cord plug in the outlet and
repeat the test.

3. Design Alteration Warning - Do not alter or add
to the mechanical or electrical design of this TV
receiver. Design alterations and additions,
including, but not limited to circuit modifications
and the addition of items such as auxiliary audio
and/or video output connections, might alter the
safety characteristics of this receiver and create a
hazard to the user. Any design alterations or
additions will void the manufacturer's warranty and
may make you, the servicer, responsible for
personal injury or property damage resulting
therefrom.

4. Hot Chassis Warning ­a. Some TV receiver chassis are electrically

connected directly to one conductor of the AC
power cord and maybe safety-serviced without
an isolation transformer only if the AC power
plug is inserted so that the chassis is
connected to the ground side of the AC power
source. To confirm that the AC power plug is
inserted correctly, with an AC voltmeter,
measure between the chassis and a known
earth ground. If a voltage reading in excess of

1.0 V is obtained, remove and reinsert the AC
power plug in the opposite polarity and again
measure the voltage potential between the
chassis and a known earth ground.

b. Some TV receiver chassis normally have 85V

AC(RMS) between chassis and earth ground
regardless of the AC plug polarity. This chassis
can be safety-serviced only with an isolation
transformer inserted in the power line between
the receiver and the AC power source, for both
personnel and test equipment protection.

c. Some TV receiver chassis have a secondary

ground system in addition to the main chassis
ground. This secondary ground system is not
isolated from the AC power line. The two
ground systems are electrically separated by
insulation material that must not be defeated or
altered.

5. Observe original lead dress. Take extra care to
assure correct lead dress in the following areas: a.
near sharp edges, b. near thermally hot parts-be
sure that leads and components do not touch
thermally hot parts, c. the AC supply, d. high
voltage, and, e. antenna wiring. Always inspect in
all areas for pinched, out of place, or frayed wiring.
Check AC power cord for damage.

6. Components, parts, and/or wiring that appear to
have overheated or are otherwise damaged
should be replaced with components, parts, or
wiring that meet original specifications.
Additionally, determine the cause of overheating
and/or damage and, if necessary, take corrective
action to remove any potential safety hazard.

7. Product Safety Notice - Some electrical and
mechanical parts have special safety-related
characteristics which are often not evident from
visual inspection, nor can the protection they give
necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc.
Parts that have special safety characteristics are
identified by a # on schematics and in parts lists.
Use of a substitute replacement that does not
have the same safety characteristics as the
recommended replacement part might create
shock, fire, and/or other hazards. The product's
safety is under review continuously and new
instructions are issued whenever appropriate.
Prior to shipment from the factory, our products
are strictly inspected to confirm they comply with
the recognized product safety and electrical codes
of the countries in which they are to be sold.
However, in order to maintain such compliance, it
is equally important to implement the following
precautions when a set is being serviced.

2-2 LTVN_ISP

Precautions during Servicing

A. Parts identified by the # symbol are critical for

safety.
Replace only with part number specified.

B. In addition to safety, other parts and assemblies

are specified for conformance with regulations
applying to spurious radiation. These must also be
replaced only with specified replacements.
Examples: RF converters, RF cables, noise
blocking capacitors, and noise blocking filters, etc.

C. Use specified internal wiring. Note especially:

1) Wires covered with PVC tubing

2) Double insulated wires

3) High voltage leads

D. Use specified insulating materials for hazardous

live parts. Note especially:

1) Insulation Tape

2) PVC tubing

3) Spacers

4) Insulators for transistors.

E. When replacing AC primary side components

(transformers, power cord, etc.), wrap ends of
wires securely about the terminals before
soldering.

F. Observe that the wires do not contact heat

producing parts (heat sinks, oxide metal film
resistors, fusible resistors, etc.)

G. Check that replaced wires do not contact sharp

edged or pointed parts.

H. When a power cord has been replaced, check that

11~13 lb (5~6 kg) of force in any direction will not
loosen it.

I. Also check areas surrounding repaired locations.
J. Use care that foreign objects (screws, solder

droplets, etc.) do not remain inside the set.

K. When connecting or disconnecting the internal

connectors, first, disconnect the AC plug from the
AC supply outlet.

L. When installing parts or assembling the cabinet

parts, be sure to use the proper screws and
tighten certainly.

2-3 LTVN_ISP

Safety Check after Servicing

Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and
wires have been returned to original positions. Afterwards, perform the following tests and confirm the specified
values in order to verify compliance with safety standards.

1. Clearance Distance

When replacing primary circuit components, confirm
specified clearance distance (d) and (d') between

Instructions for Handling Semi­conductors

Electrostatic breakdown of the semi-conductors may
occur due to a potential difference caused by
electrostatic charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a grounding band (1 MΩ) that is
properly grounded to remove any static electricity that
may be charged on the body.

2. Ground for Workbench

Be sure to place a conductive sheet or copper plate
with proper grounding (1 MΩ) on the workbench or
other surface, where the semi-conductors are to be
placed. Because the static electricity charge on
clothing will not escape through the body grounding
band, be careful to avoid contacting semi-conductors
with your clothing.

Precautions concerning the LCD Panel
Assembly:

1. When you disassemble the LCD Panel
Assembly

• Be careful not to scratch the Reflection Sheet with

the edge of Rear Frame when disassembling/
re-assembling it.

• Be careful not to drop any plastic chip on the

Reflection Sheet when/after you remove the Screws.

• Prohibit to put any external pressure on the

Reflection Sheet because the scratch on the back of
the Reflection Sheet have direct repercussion on the
display screen.

• Prohibit to put any external pressure on the Sheet

Holder or LED Heat Sink Assembly either because it
also has repercussion on the display screen via the
Reflection Sheet.

• You need to remove any visible dust from the

Reflection Sheet which creates the external
pressure between the Reflection Sheet and the
Sheet Holder/LED Heat Sink Assembly as a result.

• To prevent the Screw from being stripped, the screw

tightening torque should be 13.23 lbf·in(6 kgf·cm) for
the Rear Frame Screw and 5.512 lbf·in(2.5 kgf·cm)
for the LED Heat Sink Assembly Screw.

• Do not pull the FFC Cable and Board Cable

forcefully when you re-assemble.

4-1 FL12.1_DC

2. When you disassemble/re-assemble the
Function CBA on the Front Cabinet

• Detach the Function CBA, which is attached on the

Front Cabinet with double-sided tape, without
breaking it.

• When you put the Function CBA back on the New

Front Cabinet, you need to use specified new
double-sided tape and put the Function CBA onto
the New Front Cabinet with equal pressure to the
Board. (The gap more than 0.015 inch (0.4 mm)
between the Front Cabinet and Function CBA will
impair the sensor sensitivity.)

• Prepare for substitutional Function CBA in case you

break it when you detach it from the Front Cabinet.

3. Performance Test after reassembling the LCD
Panel Assembly

• After you swap any of the Front Cabinet, Rear Frame

or Function CBA, you need to make sure that there
is no Gomikami/Black Spot with foreign material or
Mura/White Spot on the display screen.

• Make sure there is no malfunction on the display

screen by checking the White Mode and White 20%
Mode in the Purity Check Mode.

• Check the operational sensitivity on Touch Sensor

Control Panel to make sure everything functions
normally.

SCHEMATIC DIAGRAMS / CBA AND TEST POINTS

Standard Notes

WARNING

Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical components
having such features are identified by the mark “#” in
the schematic diagram and the parts list. Before
replacing any of these components, read the parts list
in this manual carefully. The use of substitute
replacement parts that do not have the same safety
characteristics as specified in the parts list may create
shock, fire, or other hazards.

Notes:

1. Do not use the part number shown on these
drawings for ordering. The correct part number is
shown in the parts list, and may be slightly
different or amended since these drawings were
prepared.

2. All resistance values are indicated in ohms
(K = 10

3. Resistor wattages are 1/4W or 1/6W unless
otherwise specified.

4. All capacitance values are indicated in µF
(P = 10

5. All voltages are DC voltages unless otherwise
specified.

6.

This schematic diagrams are masterized version
that should cover the entire FL12.1 chassis models.
Thus some parts in detail illustrated on this
schematic diagrams may vary depend on the
model within the FL12.1 chassis.
Please refer to the parts lists for each models.

7. The Circuit Board layout illustrated on this service
manual is the latest version for this chassis at the
moment of making this service manual.
Depend on the mass production date of each
model, the actual layout of each Board may differ
slightly from this version.

NOTE:

The voltage for parts in hot circuit is measured using
hot GND as a common terminal.

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F601) is blown , check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.

4A 125V

CAUTION ! :

For continued protection against risk of fire,
replace only with same type 4A, 125V fuse.

ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.

Because a hot chassis ground is present in the power supply
circuit, an isolation transformer must be used when repairing.
Also, in order to have the ability to increase the input slowly,
when troubleshooting this type of power supply circuit,
a variable isolation transformer is required.
