1. SAFETY PRECAUTIONS

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

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.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage

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 par ts which have these special safety
characteristics are identified
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
does not have the same safety characteristics as the
PIONEER recommended replacement one, show
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
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.

(Printed on the Rear Panel )

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 Q307 (650nm LD) and Q308 (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.

1. SERVICE PRECAUTIONS

1.1 NOTES ON SOLDERING

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.

A

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 w

eight of the tip of

the soldering iron.

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

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).

B

The following lead-free solders

are available as service parts:

• Par ts numbers of lead-free solder:

GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.

METHOD FOR DIAGNOSING DEGRADATION OF THE LDS ON THE PICKUP ASSY

Case when this diagnosis is required :

When playback of any disc, including a test disc (DVD: GGV1025, CD: STD-905), won't play or doesn't play

A

How to diagnose

In the case mentioned above, degradation of the laser diodes (LDs) mounted on the 05SD Pickup Assy is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.

No playback of a CD :

Measure the voltage between the both ends of R321 or R326 on the DVDM
Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded.

B

If the measurements show degradation
of an LD, replace the 05SD Pickup Assy.

No playback of a DVD (Test Mode), No playback of a SACD :

Measure the voltage between the both ends of R322 or R325 on the DVDM
Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded.

Power-on in DVD mode

With the AC power off, turn the AC power on by pulling up Pin 44 of IC2101 with 5 V (by short-circuiting R2109).

Note: When the unit is turned on in DVD mode, "-DV D-" is indicated on the LCD.

2 Displaying the version of the mechanical control computer

Press the [ESC] then the [CHAP] key on the remote control unit for DVD Test mode (GGF1381) to indicate the version of
the mechanical control computer.
Ex. (1) : This means that the part number is " AYW7153 ".
(2) : This means that the version is " 1.06 ".

3 Canceling version display

• Press the [ESC] key on the remote control unit.

• Press the [POWER] button to turn the unit off.

Note: Even if you intend to continuously use the unit after displaying the error rate, be sure to turn the power off then back
on again.
