Safety Instructions, Warnings and Notes

2. Safety Instructions, Warnings and Notes

** To prevent the risks of unit damage, electrical shock and radiation, take the following safety, service, and ESD precautions.

2.1 Safety instructions 

It is not allowed to operate the FTV-set without glass plate. One
function of this glass plate is to absorb Infrared Radiation.
Without this glass plate the level of Infrared Radiation produced
by the plasma display could damage your eyes.

1. Safety regulations require that during a repair: – the set should be connected to the mains via an

isolating transformer ( in this particular case a
transformer of

– safety components, indicated by the symbol 

should be replaced by components identical to the
original ones;

2. Safety regulations require that after a repair the set must
be returned in its original condition. In particular attention
should be paid to the following points.
– Note: The wire trees should be routed correctly and

fixed with the mounted cable clamps.

– The insulation of the mains lead should be checked for

external damage.

– The electrical DC resistance between the mains plug

and the secondary side should be checked (only for
sets that have mains isolated power supply). This
check can be done as follows:

– unplug the mains cord and connect a wire between the

two pins of the mains plug;

– set the mains switch to the on position (keep the mains

cord unplugged!);

– measure the resistance value between the pins of the

mains plug and the metal shielding of the tuner or the
aerial connection on the set. The reading should be
between 4.5 M

– switch off the TV and remove the wire between the two

pins of the mains plug.

– The cabinet should be checked for defects to avoid

touching of any inner parts by the customer.

≥ 800 VA);

Ω and 12 MΩ;

2.2 Warnings

1. ESD 
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD
during repair can reduce life drastically. When repairing,
make sure that you are connected with the same potential
as the mass of the set by a wristband with resistance.
Keep components and tools also at this same potential.

2. Available ESD protection equipment: – complete kit ESD3 (combining all 6 prior products -

small table mat) 4822 310 10671

– wristband tester 4822 344 13999

3. Never replace modules or other components while the unit is switched on.

4. When making settings, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.

). Careless handling

• PDP module has a lot of electric devices. Service engineer
must wear equipment(for example, earth ring) to prevent
electric shock and working clothes to prevent electrostatic.

• PDP module use a fine pitch connector which is only
working by exactly connecting with flat cable. Operator
must pay attention to a complete connection when
connector is reconnected after repairing.

• The capacitor’s remaining voltage in the PDP module’s
circuit board temporarily remains after power is off.
Operator must wait for discharging of remaining voltage
during at least 1 minute.

2.4 Safety Precautions for Service (Handling, prevention of a electrical shock)

2.4.1 (Safety Precautions)

• Before replacing a board, discharge forcibly

• The remaining electricity from board.

• When connecting FFC and TCPs to the module, recheck

that they are perfectly connected.

• To prevent electrical shock, be careful not to touch leads

during circuit operations.

• To prevent the Logic circuit from being damaged due to

wrong working, do not connect/disconnect signal cables
during circuit operations.

• Do thoroughly adjustment of a voltage label and voltage-

insulation.

• Before reinstalling the chassis and the chassis assembly,

be sure to use all protective stuffs including a nonmetal
controlling handle and the covering of partitioning type.

• Caution for design change : Do not install any additional

devices to the module, and do not change the electrical
circuit design.

• For example: Do not insert a subsidiary audio or video

connector. If you insert It, It cause danger on safety. And,
If you change the design or insert, Manufactor guarantee
will be not effect. .

• If any parts of wire is overheats of damaged, replace it with

a new specified one immediately, and identify the cause of
the problem and remove the possible dangerous factors.

• Examine carefully the cable status if it is twisted or

damaged or displaced. Do not change the space between
parts and circuit board. Check the cord of AC power
preparing damage.

• Product Safety Mark: Some of electric or implement

material have special characteristics invisible that was
related on safety. In case of the parts are changed with new
one, even though the Voltage and Watt is higher than
before, the Safety and Protection function will be lost.

• The AC power always should be turned off, before next

repair..

• Check assembly condition of screw, parts and wire

arrangement after repairing. Check whether the material
around the parts get damaged.

2.3 Handling Precautions for Plasma Display

• PDP module use high voltage that is dangerous to human.
Before operating PDP, always check the dust to prevent
short circuit. Be careful touching the circuit device when
power is on.

• PDP module is sensitive to dust and humidity. Therefore,
assembling and disassembling must be done in no dust
place.

2.4.2 (Precaution when repairing ESD)

• There is ESD which is easily damaged by
electrostatics.(for example Integrated circuit, FET)
Electrostatic damage rate of product will be reduced by the
following technics

• Before handling semiconductor parts/assembly, must
remove positive electric by ground connection, or must
wear the antistatic wrist-belt and ring. (It must be operated
after removing dust on it - It comes under precaution of
electric shock.)

Safety Instructions, Warnings and Notes

EN 7S/SD/HD 3.1 PDP 2.

• After removing ESD assembly, put on it with aluminum stuff
on the conductive surface to prevent charging.

• Do not use chemical stuff using Freon. It generates positive electric that can damage ESD.

• Must use a soldering device for ground-tip when soldering or de-soldering ESD.

• Must use anti-static solder removal device. Most removal
device do not have antistatic which can charge a enough
positive electric enough damaging ESD.

• Before removeing the protective material from the lead of a
new ESD, bring the protective material into contact with the
chassis or assembly that the ESD is to be installed on.

• When handing an unpacked ESD for replacement, do not
move around too much. Moving (legs on the carpet, for
example) generates enough electrostatic to damage the
ESD.

• Do not take a new ESD from the protective case until the
ESD is ready to be installed. Most ESD have a lead, which
is easily short-circuited by conductive materials (such as
conductive foam and aluminum)

2.5 Notes

A glass plate is positioned before the plasma display. This
glass plate can be cleaned with a slightly humid cloth. If
due to circumstances there is some dirt between the glass
plate and the plasma display panel it is recommended to do
some maintenance by a qualified service employee only.

• Routing of the wires and fixing them in position must be
done in accordance with the original routing and fixing
configuration when servicing is completed. All the wires are
routed far away from the areas that become hot (such as
the heat sink). These wires are fixed in position with the
wire clamps so that the wires do not move, thereby
ensuring that they are not damaged and their materials do
not deteriorate over long periods of time. Therefore, route
the cables and fix the cables to the original position and
states using the wire clamps.

• Perform a safety check when servicing is completed. Verify
that the peripherals of the serviced points have not
undergone any deterioration during servicing. Also verify
that the screws, parts and cables removed for servicing
purposes have all been returned to their proper locations in
accordance with the original

2.5.1 Notes on safe handling of the plasma display

Notes to follow during service

• The work procedures shown with the Note indication are
important for ensuring the safety of the product and the
servicing work. Be sure to follow these instructions.

• Before starting the work, secure a sufficient working space.

• At all times other than when adjusting and checking the
product, be sure to turn OFF the main POWER switch and
disconnect the power cable from the power source of the
display (jig or the display itself) during servicing.

• To prevent electric shock and breakage of pwb, start the
servicing work at least 30 seconds after the main power
bas been turned off. Especially when installing and
removing the power supply pwb and the SUS pwb in which
high voltages are applied, start servicing at least 2 minutes
after the main power bas been turned off.

• While the main power is on, do not touch any parts or
circuits other than the ones specified. The high voltage
power supply block within the PDP module has a floating
ground. If any connection other than the one specified is
made between the measuring equipment and the high
voltage power supply block, it can result in electric shock or
activation of the leakage-detection circuit breaker.

• When installing the PDP module in, and removing it from
the packing carton, be sure to have at least two persons

• perform the work white being careful to ensure that the
flexible printed-circuit cable of the PDP module does not

• get caught by the packing carton.

• When the surface of the panel comes into contact with the
cushioning materials, be sure to confirm that there is no
foreign matter on top of the cushioning materials before the
surface of the panel comes into contact with the cushioning
materials. Failure to observe this precaution may result in,
the surface of the panel being scratched by foreign matter.

• When handling the circuit pwb, be sure to remove static
electricity from your body before handling the circuit pwb.

• Be sure to handle the circuit pwb by holding the large parts
as the heat sink or transformer. Failure to observe this
precaution may result in the occurrence of an abnormality
in the soldered areas.

• Do not stack the circuit pwb. Failure to observe this
precaution may result in problems resulting from scratches
on the parts, the deformation of parts, and short-circuits
due to residual electric charge.
