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

D

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.

E

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.

• When the front case is removed, infrared ray is radiated and
may disturb reception of the remote control unit.

• 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.

Leakage Current Cold 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.
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.), particularly any exposed metal part having a return
path to the chassis. Exposed metal parts having a return path to
the chassis should have a minimum resistor reading of 0.3MΩ
and a maximum resistor reading of 5MΩ. Any resistor value
below or above this range indicates an abnormality which requires
corrective action. Exposed metal parts not having a return path to
the chassis will indicate an open circuit.

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 (Simpson Model 229
equivalent)", 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,
conduit, etc.). Any current measured must not exceed 0.5mA.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in PIONEER set have
special safety related characteristics. These are often not evident
from visual inspection nor the protection afforded by them
necessarily can be obtained by using replacement components
rated for higher voltage, wattage, etc. Replacement parts which
have these special safety characteristics are identified in this
Service Manual.
Electrical components having such features are identified by
marking with a on the schematics and on the parts list in this
Service Manual.
The use of a substitute replacement component which dose not
have the same safety characteristics as the PIONEER
recommended replacement one, shown in the parts list in this
Service Manual, may create shock, fire or other hazards.
Product Safety is continuously under review and new instructions
are issued from time to time. For the latest information, always
consult the current PIONEER Service Manual. A subscription to,
or additional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

CAUTION

• Observe the caution matter, without fail

• The caution matters of given in the delivery specifications, etc., must be observed, without fail.

• Do not give shocks and vibration.

• The panel surface (display plane) of the PDP module is made of glass. If any shocks or vibration is applied, it may be broken and
the scattered glass chips will be a cause of injury

• Do not put anything.

B

• Transportation must be done by enough personnel.

• Do

not put anything on the PDP module. Otherwise, this can be a cause of injury as a result of falling down or dropping caused

by imbalance.

• The PDP module is heavy. In the case of transportation, unpacking, or packing, more than two persons should do it by supporting
the top and the bottom of the product.

7 Miscellaneous caution matters

(1) This PDP module 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) For this product, the PDP modules and the PWBs are repaired by replacement in a unit. Therefore, the units of

C

the PWBs must not be repaired or disassembled. Otherwise, the validity of warranty will be lost.

(3) If this PDP module 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.

(4) When a PDP module 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 should

D

be incorporated in the product and aging treatment should be carried out for about two hours (all screen display).

(5) Sulfides will deteriorate the PDP module 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.

(6) When taking out a PDP module from the maintenance package box, do it slowly so that the panel surface

does not get any shock or stress.

(7) If one touches the connector of the flexible cable exposed to the rear side of the PDP module, 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.

(8) The panel surface of the PDP module is easy to be hurt and generate cracks. Therefore, it should be handled

very carefully. Never press or rub it with a hard thing. Never put it on a hard thing with the panel surface faced
downwards.

(9) When the panel surface of the PDP module is contaminated, gently wipe off the contaminant with a piece of

E

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. The cloth for
wiping off should be clean. Never use the same cloth 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.

(10) When transporting this PDP module, use the packing materials specified in the list of parts. Once used,

such packing materials should not be used again.

(11) The PDP module is composed of a variety of parts, such as those made of materials like glass, metal,

plastics, etc. Therefore, when abandoning the PDP module, this should be done in accordance with the
relevant law of the nation or an autonomous body

Useful Tips

1. The CPU have two 12C for system controller.
One is communicate with system 12C(TDA10046) and the other is communicate with serial EFPROM for storing data.

2. When the system will not operate even though the basic inspection results were normal, check Flash Memory which
contains channel data and program contents.

3. Additionally check for Local DATA and Local ADDRESS buses between CPU and Flash Memory.

4. When replacing parts, be careful of static changes from the tip of the solder iron that can easily damage the parts.
Also, check for assembly condition, soldering condition, or for incorrect or reverse insertion of parts.
