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 cer tain electrical par ts contain chemicals which are known to the state of California to

cause cancer, bir th 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)

Les symboles de fusible

(fusible de type rapide)

et/ou

(fusible de type lent) sur CCI indiquent que

les pièces de remplacement doivent avoir la même désignation.

ANY MEASUREMENTS NOT WITHIN THE

LIMITS OUTLINED ABOVE ARE INDICATIVE

OF A POTENTIAL SHOCK HAZARD AND

MUST BE CORRECTED BEFORE RETURN-

ING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance

have special safety related character istics. 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 par ts which have these

special safety character istics are identified in this

Service Manual.

Electr ical 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

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

infor mation, always consult the current PIONEER

Service Manual. A subscription to, or

additional copies

of, PIONEER Ser vice Manual may be obtained at a

nominal charge from PIONEER.

(FOR USA MODEL ONLY)

1. SAFETY PRECAUTIONS

The following check should be perfor med for the

continued protection of the customer and ser vice

technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known ear th ground

(water pipe, conduit, etc.) by connecting a leakage

current tester such as Simpson Model 229-2 or

equivalent between the ear th ground and all exposed

metal par ts of the appliance (input/output ter minals,

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.

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

WAVELENGTH : 780 nm

Additional Laser Caution

: See page 61.

1. Laser Interlock Mechanism

· Loading switch (S101 on the LOAB Assy) is used for interlock

mechanism of the laser.

When this switch turned ON in SW2 (CLOSE) side (OPEN signal is

0V and CLOSE signal is 3.5V), a laser becomes the status which can

completely oscillation.

Furthermore, the laser completely oscillates in the disc judgment and

disc playback.

When player is power ON state and laser diode is not completely

oscillating, 780nm laser diode is always oscillating by half power.

· Laser diode is driving with Q7 (650nm LD) and Q8 (780nm LD)

on the DVDM 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.

The interlock mechanism mentioned above becomes invalid in this

mode.

2. When the cover is open, close viewing through the objective lens with

the naked eye will cause exposure to the laser beam.
