SAFETY INFORMATION

A

This service manual is intended for qualified service technicians; it is not meant for the casual
do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been
trained to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.

WARNING
This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to

B

cause cancer, birth defects or other reproductive harm.
Health & Safety Code Section 25249.6 – Proposition 65

NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement
parts must be of identical designation.

REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)

1. SAFETY PRECAUTIONS

The following check should be performed for the
continued protection of the customer and service
technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or

D

equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5 mA.

ANY MEASUREMENTS NOT WITHIN THE
LIMITS OUTLINED ABOVE ARE INDICATIVE
OF A POTENTIAL SHOCK HAZARD AND
MUST BE CORRECTED BEFORE RETURN­ING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance
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 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 parts list in this Service Manual.
The use of a substitute replacement component which
does 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.

WARNING !

THE AEL (ACCESSIBLE EMISSION LEVEL) OF THE LASER POWER OUTPUT IS LESS THAN CLASS 1
BUT THE LASER COMPONENT IS CAPABLE OF EMITTING RADIATION EXCEEDING THE LIMIT FOR
CLASS 1.
A SPECIALLY INSTRUCTED PERSON SHOULD DO SERVICING OPERATION OF THE APPARATUS.

LASER DIODE CHARACTERISTICS

FOR DVD : MAXIMUM OUTPUT POWER : 5 mW

WAVELENGTH : 650 nm

FOR CD : MAXIMUM OUTPUT POWER : 5 mW

LABEL CHECK

Location: inside of the unit

(Printed on the Rear Panel)

Additional Laser Caution

1.

• Laser diode is driving with Q2303,Q2305(650nm LD) and Q2302,
Q2304(780nm LD)on the DVD MT PCB Assy.
Therefore, when short-circuit between the emitter and collector of these
transistors or the base voltage is supplied for transistors turn on, the
laser oscillates. (failure mode)

• In the test mode ∗ , there is the mode that the laser oscillates except
for the disc judgment and playback. LD ON mode in the test mode
oscillates with the laser forcibly.

2. When the cover is open, close viewing through the objective lens with
the naked eye will cause exposure to the laser beam.

1. SERVICE PRECAUTIONS

1.1 NOTES ON SOLDERING

NOTES ON SOLDERING

A

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled.

B

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

1.2 WHEN REPLACING DVD DECK

C

WHEN REPLACING DVD DECK

[ Removing the DVD Deck ]

Before removing Pick Up PCB and DVD PCB connector, short circuit the position shown in Fig. 1 using
a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged.

[ Installing the DVD Deck ]

Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD

D

E

PCB connector.

NOTE

•

Before your operation, please read “PREPARATION OF SERVICING” .

•

Use the Lead Free solder.

•

Manual soldering conditions

• Soldering temperature: 320 ± 20˚C

• Soldering time: Within 3 seconds

• Soldering combination: Sn-3.0Ag-0.5Cu

•

When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the
Flux smoke from it.

Short circuit using a
soldering iron.

PREPARATION OF SERVICING

C

D

The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is
received at the time of repair, the life of the product may be shortened.
Please perform the following measure against static electricity, be careful of destruction of a
laser diode at the time of repair.

• Place the unit on a workstation equipped to protect against static electricity, such as
conductive mat.

• Soldering iron with ground wire or ceramic type is used.

• A worker needs to use a ground conductive wrist strap for body.
