Safety Instructions, Warnings and Notes

2. Safety Instructions, Warnings and Notes

EN 3ALIS-PDP Suppl. 2.

2.1 Safety 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 M 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.

2.2 Warnings

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.

2.3 Notes

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.

2.3.1 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 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.

4.1.2 Aluminium 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.

4.1.3 Foam Bars

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).
