Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 15SDI PDP 2.

Index of this chapter:

2.1 Handling Precautions

2.2 Safety Precautions

2.3 Notes

Notes:

• Only authorised persons should perform servicing of this module.

• When using/handling this unit, pay special attention to the PDP Module: it should not be enforced into any other way then next rules, warnings, and/or cautions.

• "Warning" indicates a hazard that may lead to death or injury if the warning is ignored and the product is handled incorrectly.

• "Caution" indicates a hazard that can lead to injury or damage to property if the caution is ignored and the product is handled incorrectly.

2.1 Handling Precautions

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

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

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

• The PDP module use a fine pitch connector which is only working by exactly connecting with flat cable. The 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.

2.2 Safety Precautions

2.2.1 Safety Precautions

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.

2.2.2 ESD Precautions

There are parts, which are easily damaged by electrostatics (for example Integrated Circuits, FETs, etc.) 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).

• After removing the assembly, lay it with the tracks on a conductive surface to prevent charging.

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

• You must use a soldering device for ground-tip when soldering or de-soldering these devices.

• You must use anti-static solder removal device. Most removal devices do not have antistatic which can charge a enough positive electric enough for damaging these devices.

• Before removing the protective material from the lead of a new device, bring the protective material into contact with the chassis or assembly.

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

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

• 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 stuff 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, manufacturer 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

2.3 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.

2.3.1 Safe PDP Handling

• 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 PWBs, start the servicing work at least 30 seconds after the main power has 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 has been turned “off”.

EN 16 SDI PDP3.

Directions For Use

• 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 while 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

3. Directions For Use

Not applicable.

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.

• 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
