Safety Instructions, Warnings and Notes
2.Safety Instructions, Warnings and Notes
EN 3ALIS-PDP Suppl.2.
2.1Safety instructions h
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 ≥ 800 VA);
– safety components, indicated by the symbol h ,
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 a 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 MΩ and 12 MΩ;
•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.
2.2Warnings
1. ESD w
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling 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.
1. Available ESD protection equipment:
– complete kit ESD3 (combining all 6 prior products -
small table mat) 4822 310 10671
– wristband tester 4822 344 13999
2. Never replace modules or other components while the unit
is switched on.
3. When making settings, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.3Notes
1. 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.
2. Never disconnect the power display cable when the set is
operating
3. With DST no failures (error-codes) can be red, when the
set is in Service-mode.
4. If DST reacts with "error 2", there is no communication
between set and DST. Note that IR-transmitter LED is
positioned at right side of IR-receiver eye of the E-box.
Take into account that receiver-LED on DST is positioned
not in the middle but at the left side. Point corresponding
LED"s to each other. In case the amount of Infrared
produced by the screen pollutes the communication, the
set can be set in Standby-mode. Then still the errormessages can be retrieved.
2.3.1Notes 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 PC board, start
the servicing work at least 30 seconds after the main power
bas been turned off. Especially when installing and
removing the power supply PC board and the SUS PC
board 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 PC board, be sure to remove
static electricity from your body before handling the circuit
PC board.
•Be sure to handle the circuit PC board 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 PC boards. 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.
•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 setup

position. A better solution to access the IR-LED and/or ON/
OFF switch is to make some holes in the stands at the
position of the LED and switch. Do not make the holes to
big, as this will influence the strength of the stands.

Figure 4-1 Transport cushions
First, put the monitor in its service position. Therefore,
disconnect all cables connected to the monitor and take the
monitor of the wall (or tabletop stand). Then, place the monitor
in the re-enforced transport cushions that function also as
service stand (you can order them separately under code 3122
126 40612). See figure "Transport cushions".
Notes:
•There are no special "re-enforced service stands". The
cushions used in the factory packaging are already made
of reinforced material.
•Always keep in mind that the stands are only designed to
keep the monitor in service position as long as the monitor
is being serviced. The stands are NOT designed to keep
the monitor in the upright position for more then two days.
•After the monitor is serviced, or when nobody is working on
the monitor (e.g. in the weekend), it should be removed
from the stands and laid down on a cushion or other
support system to prevent it from falling.
•Worn out stands should be replaced by new ones (monitor
will tilt to much forward).
•Never leave the monitor alone when the stands are not fully
pressed on its place.
•It is possible to move the right stand a bit to the right so that
you can access the IR-LED and ON/OFF switch, but the
monitor can then not be left alone because the stands are
NOT designed to carry the weight of the monitor in that
Figure 4-2 Aluminium stands
The aluminium stands (order code 3122 785 90480) can be
mounted with the back cover removed or still left on. So, the
stand can be used to store products or to do measurements. It
is also very suitable to perform duration tests without taking
much space, without having the risk of overheating and no risk
of products falling. The stands can be mounted and removed
quickly and easy with use of the delivered screws that can be
tightened and loosened manually without the use of tools. See
figure above.
Note: Only use the delivered screws to mount the monitor to
the stands.

CL 36532051_002.eps
Figure 4-3 Foam bars
The foam bars (order code 3122 785 90580) can be used for
all types and sizes of FTVs and LCD TVs and can even be used
to e.g. exchange a CRT of a normal TV. By laying the plasma
or LCD TV flat on the (ESD protective) foam bars, a stable
situation is created to perform measurements and alignments.
See figure "Foam stand".
By first placing a mirror flat on the table under the TV you can
easily see if something is happening on the screen. The bars
are also handy to replace the screen (PDP or LCD).
