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.

2.1Safety 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 ≥ 800 VA);

–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 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

All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ). 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.

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.

2.3Handling 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.

•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.

2.4Safety 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 voltageinsulation.

•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.

2.4.2(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

S/SD/HD 3.1 PDP

EN 7

•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)

•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

2.5Notes

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.

2.5.1Notes 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 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.
