SAFETY PRECAUTIONS
NOTICE : Comply with all cautions and safety related notes
located on or inside the cabinet and on the chassis.
The following precautions should be observed :
1. When service is required, even though the PDP UNIT an
isolation transformer should be inserted between the power line
and the set in safety before any service is performed.
2. When replacing a chassis in the set, all the protective devices
must be put back in place, such as barriers, nonmetallic knobs,
adjustment and compartment covershields, isolation resistorcapacitor, etc.
3. When service is required, observe the original lead dress. Extra
precaution should be taken to assure correct lead dress in the
high voltage circuitry area.
4. Always use the manufacture's replacement components.
Especially critical components as indicated on the circuit
diagram should not be replaced by other manufacture's.
Furthermore where a short circuit has occurred, replace those
components that indicate evidence of overheating.
5. Before returning a serviced set to the customer, the service
technician must thoroughly test the unit to be certain that it is
completely safe to operate without danger of electrical shock,
and be sure that no protective device built into the set by the
manufacture has become defective, or inadvertently defeated
during servicing. Therefore, the following checks should be
performed for the continued protection of the customer and
servicetechnician.
6. Perform the following precautions against unwanted radiation
and rise in internal temperature.
• Always return the internal wiring to the original styling.
• Attach parts (Gascket, Ferrite Core, Ground, Rear Cover,
Shield Case etc.) surely after disassembly.
7. Perform the following precautions for the PDP panel.
• When the front case is removed, make sure nothing hits the
panel face, panel corner, and panel edge (so that the glass does
not break).
• Make sure that the panel vent does not break. (Check that the
cover is attached.)
• Handle the FPC connected to the panel carefully.
Twisting or pulling the FPC when connecting it to the
connector will cause it to peel off from the panel.
8. Pay attention to the following.
• Pay extreme caution when the front case and rear panel are
removed because this may cause a high risk of disturbance to
TVs and radios in the surrounding.

Insulation Resistance Check
With the AC plug removed from an AC power source, place a
jumper across the two plug prongs. Turn the AC power switch on.
( Case of PD6001, AC power is alwayas on. )
(Case of PX-60XR5A, AC power is always on.)
Using an insulation tester (DC 500V), connect one lead to the
jumpered AC plug and touch the other lead to each exposed metal
part (input/output terminals, screwheads, metal overlays, control
shafts, etc.), The resistance should be greater than 4 MΩ.
Leakage Current Hot Check
Plug the AC line cord directly into an AC power source (do not
use an isolation transformer for this check).
Turn the AC power switch on.
Using a "Leakage Current Tester", measure for current from all
exposed metal parts of the cabinet (input/output terminals,
screwheads, metal overlays, control shaft, etc.), particularly any
exposed metal part having a return path to the chassis, to a known
earth ground (water pipe, etc.). Any current measured must not
exceed 1.0 mA.

Safety cautions
The matters to be observed without fail are explained below. These matters are indispensable for the
prevention of an accident during the maintenance servicing, the "security of products" after the completion of
servicing work, and the "prevention of the repeated occurrence of similar fault."
(1) The degree of danger and material damage, caused as a result of wrong use by disregarding the contents
of the display" is distinguished and explained in the table below.
If this display is disregarded and equipment is handled

wrongly, this can be a cause of physical injury and a
fire, thus leading a person to death or serious injury.
If this display is disregarded and equipment is
handled wrongly, this may lead to personal injury or
material damage.
This icon indicates the contents of "caution" that must be practiced, without fail.
WARNING
• Observe the caution matter, without fail.
• In the place where a particular caution is needed during maintenance servicing, such a
caution note is displayed with a label or a stamp that is given to the cabinet, chassis,
PWB, etc. These caution notes and also the caution matters of given in
the instruction manuals, etc., must be observed, without fail.
• Be careful of an electric shock or a burn.
• The power block or the PDP module involves the sections where high voltage or high
temperature is prevalent. When equipment is energized, use working gloves in order to
prevent an electric shock or a burn. At the time of transportation, disassembly,
reassembly, and the replacement of parts, such a servicing job must be done after pulling
out the power plug.
• Modification of equipment is absolutely prohibited. Use the specified parts at all times.
• If any modification is performed, the validity of the manufacturer's warranty is lost at that
moment. The personnel who did this modification is responsible for the physical injury or
the like, if it should occur as a result of the modification. The parts used are given the
safety-based characteristics, such as non-flammability or sufficient withstand voltage. The
parts to be replaced shall be those which are specified in the list of replacement
parts.(Example: The lithium battery (circuit symbol BT9501 in the MAIN PWB) will give
rise to explosion if its polarity is wrongly treated.
WARNING
• The replaced parts and wiring must be arranged in the original conditions.
• For safety reasons, insulation materials like tubes and tapes may be used or some parts
may be mounted clear of the PWB. The internal wiring and the fastening with the
clampers for separation from high-heat and high-voltage parts shall be returned to their
original conditions, without fail.

is made of glass. If any shocks or vibration is applied, it may be broken
CAUTION
Miscellaneous caution matters
(1) This product uses highly integrated semiconductor parts. Since these parts are fragile to
electrostatic charges, earth bands should be used for handling. The product should be handled
where measures have been taken against electrostatic charges.
(2) If this product is used for the fixed character display or the like as in the case of a character
display board, a phenomenon of burning (not warranted) will occur. Burning is a phenomenon
that the unevenness in the brightness is caused in the display. In such a case, the brightness in
the section where the integrated display time is longer becomes lower than the brightness in
another section where the integrated display time is shorter. This phenomenon is in proportion
to the integrated display time and the brightness. For this reason, to relieve this difficulty during
servicing, do not use any still picture, but use a display by motion pictures of a video or the like.
In addition, use "FULL" for the screen mode and avoid using any display by "NORMAL",
"TRUE", or MULTI SCREEN like side by side etc. If it is necessary to use only a still picture for
unavoidable reasons, use a burning relief function such as "PLE LOCK", "ORBITER",
"SCREEN WIPER", etc.
(3) When a PDP module (include the PDP Service ASSY) is operated after a long time of storage,
it may encounter a difficulty like a failure in displaying a screen or unstability according to the
condition of storage. In such a case, the PDP module (include the PDP Service ASSY) should
be incorporated in the product and aging treatment should be carried out for about two hours
(all screen display).
(4) Sulfides will deteriorate the PDP module (include the PDP Service ASSY) and this is a cause of
malfunction. Therefore, it is absolutely prohibited to put any vulcanized rubber or a material
containing sulfur in the vicinity of the PDP module (include the PDP Service ASSY).
(5) When taking out a PDP module (include the PDP Service ASSY) from the maintenance
5
Page 8
package box, do it slowly so that the panel surface does not get any shock or stress.
If one touches the connector of the flexible cable exposed to the rear side of the PDP module
(6)
(include the PDP Service ASSY), there is danger of causing a poor contact. As such, it must be
handled with utmost care. In addition, the flexible cable is very weak in mechanical strength.
Therefore, this cable must not be touched during handling.
(7) The panel surface of the filter and the PDP module (include the PDP Service ASSY) is easy to
be hurt. These components should be handled very carefully not to press or rub them with a
hard thing. Never put them on a hard thing with the panel surface faced downwards.
When the panel surface of the filter and the PDP module (include the PDP Service ASSY) is
(8)
contaminated, gently wipe off the contaminant with a piece of soft dry cloth. Liquid-state
contamination can be removed by lightly pressing it, without rubbing it. If it is difficult to remove
the contamination, use a piece of cloth soaked with a neutral detergent
water.)
or a rubbing alcohol. The cloth for wiping off should be clean. Never use the same cloth
(Use it, diluting with
repeatedly. If a cleansing detergent or water drops should enter the module interior or be
attached to the module surface other than the display plane at the time of cleaning, this will give
rise to the destruction of the product when the product is energized.
(9) When transporting this product, use the packing materials specified in the list of parts. Once
used, such packing materials should not be used again.
(10) This product is composed of a variety of parts, such as those made of materials like glass,
metal, plastics, etc., and those like a lithium battery (circuit symbol of the MAIN ASSY: BT9501),
etc. Therefore, when abandoning this product, this should be done in accordance with the
relevant law of the nation or an autonomous body.
CAUTION: Risk of Explosion if Battery is replaced by an Incorrect Type. Dispose of Used
Batteries According to above the Instructions.
(11) You should use the following service tools when you replace ICs etc. since solder with free lead is
used in product.

Note: Before performing a failure diagnosis, be sure to check that the settings of the unit are properly made by referring to its
specifications and instruction manual.
If speaker outputs with different polarities or a speaker output and ground are short-circuited, the protection circuit is activated,
and audio will not be output. In this case, turn the power off at the Main Power Switch, make connections properly, then turn the
power back on again. The protection circuit will then be released.

1-1 Command format
Data format
The format of the control signal transmitted from the user side controller is as described below.
STX (02Hex) is arranged at the time of communication start and ETX (03Hex) is arranged at the time of data transmission
complete, and ID, command and parameter are arranged in between. Data consists of ASCII type alphanumeric characters,
and there is no distinction between the upper case and the lower case.
In the case of command only [single function command]
STX (02hex)ID (2 byte)Command (3 byte)ETX (03hex)
Command processing
Command processing starts as soon as the command is entered.
ID shall be the two asterisks, "∗∗". Do not input any other ID.
Acknowledgement (confirmation of reception)
The user-end controller will report its operational status and the settings to the system. The data to be sent back are in
uppercase after deleting the ID code from the received command.
After receiving a command from the system, the user-end controller will read out appropriate data from memory, according
to the type of command, and send them back to the system. The command section is composed of three characters. The
first character is fixed at Q, and the second and third characters are determined according to the content of the received
command. The return data include the received 3-character command, various data that have been converted to ASCII
codes, and a checksum. The number of bytes of the return data can vary, because the content of return data varies
according to the type of QUEST commands.

1-2-2 Acquisition of panel operation data • • • [QS2]
The command QS2 is for acquiring data on the panel's operations. Basically, this command is used for the module's
microcomputer to inform the main unit's microcomputer of changes in panel operation.
• The high-order 6 bytes of a value indicated by the Hour Meter represent hours, and the lower-order 2 bytes represent minutes.
The maximum record time is 279,620 hours 16 minutes. If the value exceeds that number, it will be reset to 0.
• The TEMP1 input value (10 bits) is transmitted in 3 bytes in decimal notation (range: 000-999) as temperature data.
Values of 1000-1023 are handled as 999. (During Standby mode, the value retained in RAM is transmitted.)
77
Page 70
1-2-3 Acquisition of other data on the panel • • • [QIP]
The command QIP is for acquiring data other than those available with QS1 (data necessary before turning the power on) and
QS2 (data to inform of operational status change).
• The high-order 6 bytes of a value indicated by the Hour Meter represent hours, and the lower-order 2 bytes represent minutes.
The maximum record time is 279,620 hours 16 minutes. If the value exceeds that number, it will be reset to 0.
• Detection of V frequency:
The V signal input to the panel is measured in the range of 30.51 Hz to 99.99 Hz. The measured value is multiplied by 100
and then output.

3.4 POWER ON/OFF FUNCTION FOR THE LARGE-SIGNAL SYSTEM
Function: It is an operational mode where the digital signal processing performs circuit operation but the power
is not supplied to the panel driving system (large signal system) in order to avoid a power down.
Application:
1. When it is necessary to check whether the signal output is correctly reaching the drive system in a repairing activity etc.
2. In the case of a PD, to determine whether the problem is with the large signal system power supply or with the small signal
system power supply.
Method:
1. Make shorting between the specified location (refer to the illustration below) of the PCB surface of the 60 DIGITAL ASSY
and the nearby pattern.
2. Execute [DRV S00] by RS232C command. ([DRV S01] for release)
Supplemental explanation:
• When the large signal system power supply is in OFF state, there will be no PD, except PD of power supply, as the PD signal has
been muted.
• If the clip is removed in the OFF state of the large signal system power supply, PD will take place at the instance of clip
removal. Therefore, be sure to remove the clip after turning the power OFF.
• Under RS232C command control, [DRVS01] (release) is possible during power ON. However, there is a possibility of
damaging the set. Therefore, make this operation only after turning the power OFF.
• Command [DRVS00/S01] is effective even during standby. When the main power is turned OFF, however, [DRVS01]
(release) will be effective.

How to count the usage time
Usage time is counted in units of hours, rounded
downward.
Note: If the unit is turned off with the Main Power
switch or by unplugging the AC power cord, the usage
time is not counted, even if the unit had been used for
more than one hour, because no power is supplied to
the microcomputer. However, the usage time is
counted if the unit is turned off with the remote control
unit.
Examples:
• If the unit is turned off by cutting power at the Main
Power switch, unplugging the AC power cord, or
using the remote control unit, after only 50 minutes
of usage, the usage time is not counted.
• If the unit is turned off by cutting power at the Main
Power switch or unplugging the AC power cord after
being used for an hour and a half then turned on by
pressing the Main Power switch or plugging in the
AC power cord after 50 minutes, the usage time is
counted as an hour.
• If the unit is turned off by using the remote control
unit after usage for an hour and a half then turned on
by using the remote control unit after 50 minutes, the
usage time is counted as 2 hours.
