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”.
Page 16
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

Important: Remove all non-default jumpers and reset all DIP switches, after the repair!
8.1 Alignments 37" SD v4
1. Set the pattern to Full White (place jumper CN2008 on the Logic Board).
2. Set Vsch (see Figure “Test point location LJ92-0102A”) to
-38V (see Figure “Waveform adjustment (Y-Board)”). Check with a digital multimeter, connected between the Y­scan test point and ground. Adjust the voltage with VR5000.
3. Check the waveform using an Oscilloscope.
• Triggering through V_TOGG of the LOGIC Board (see
Figure “Logic PWB”).
• Connect the “ODD” test point, located at the centre of
Y_buffer (see Figure “Potentiometer locations LJ92­01149A”), to the other channel, and then check the first Subfield waveform of one TV-Field.
• Check the waveform by adjusting Horizontal Division of
the oscilloscope.
4. Adjust the flat time of the rising ramp of the 1st subframe to 40 µS with VR5001 (see Figure “Rising ramp flat time adjustment”).
5. Adjust the flat time of the falling ramp of the 1st subframe to 16 µs with VR5002 (see Figure “Falling ramp flat time adjustment”).
• This is a difficult adjustment.
• It is easier and more accurate to do the following:
– Count 3 pulses between A and B; – Set the difference between A and B to 40 V; the
time between C and D will then automatically be set to approximately 16 µS
– Settings of the oscilloscope: vertically 20VDC/div,
horizontally 10 µS/div.
6. Check with the oscilloscope if the voltage of Vsch is -38 V (see Figure “Y-scan H waveform”).
Special notice: It is very important, that you execute this adjustment on the 1st Sub-Field (SF) of the 1st Frame of the Reset waveform and then move to the 3rd Sub-field for adjusting.

1. Put the dipswitches on the Logic Board in the internal position to get a Full White Pattern.
2. You can find the location of the test point and potentiometers in Figure “Potentiometer locations”.
3. Adjust Vsch to 40 V with VR5004.
4. Check the waveform with an Oscilloscope.
• Take the trigger signal from the testpoint marked “V-
sync” on the Logic Board.
• Connect the testpoint marked “OUT 4”, located in the
centre of Y_buffer Board to the other channel, and then check the first Subfield operating waveform of one TV­Field.
• Check the waveform again after adjusting Horizontal
Division. Check the Reset waveform when the V_TOGG Level is changed.
• Set the Vset to 10µs by adjusting VR5002.
• Set the Falling maintenance time to 30 µs by adjusting
VR5003.
• Change the waveform position of Oscilloscope to the
3rd Subfield and then set the Falling maintenance time to 30µsby adjusting the VR5001. GND maintenance section should be checked after the Vertical Division is readjusted to “2 V or 5 V”.
Special notice: It is very important, that you execute this adjustment on the 1st Sub-Field (SF) of the 1st Frame of the
Reset waveform and then move to the 3rd Sub-field for adjusting.

9.1 Main function of Each Assembly

9.1.1 X Main Board

The X Main board generates a drive signal by switching the FET in synchronization with logic main board timing, and supplies the X electrode of the panel with the drive signal through the connector.
1. Maintain voltage waveforms (including ERC).
2. Generate X rising ramp signal.
3. Maintain Ve bias between Scan intervals.

9.1.2 Y Main Board

The Y Main board generates a drive signal by switching the FET in synchronization with the logic Main Board timing and sequential supplies the Y electrode of the panel with the drive signal through the scan driver IC on the Y-buffer board. This board connected to the panel’s Y terminal has the following main functions.
1. Maintain voltage waveforms (including ERC).
2. Generate Y-rising Falling Ramp.
3. Maintain V scan bias.

9.1.3 Logic Main Board

The Logic Main board generates and outputs the address drive output signal and the X,Y drive signal by processing the video signals. This Board buffers the address drive output signal and feeds it to the address drive IC (COF module, video signal- X Y drive signal generation, frame memory circuit / address data rearrangement).
