(FOR USA MODEL ONLY)
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 (waterpipe
, conduit, etc.) by connecting a leakage current tester
such as Simpson Model 229-2 or equivalent between the
D
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 60Hz outlet and turn the AC power switch
on. Any current measured must not exceed 0.5mA.
Reading should

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 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
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

5. PCB PARTS LIST
NOTES:
A
Mark No. DescriptionPart No.
B
Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=
and K=10%).
560 Ω
47k Ω
0.5 Ω
1 Ω
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

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.
A
[ Installing the DVD Deck ]
Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
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
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.
E
F
• A worker needs to use a ground conductive wrist strap for body.

7.1.5 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), cannot be performed
How to diagnose
In the case mentioned above, degradation of the laser diodes (LDs) mounted on the PICKUP Assy is suspected.
Measure the voltage between the two ends of one of the resistors mentioned below.
No playback of a DVD :
Measure the voltage between the two ends of R2321 or R2323 on the DVDM
Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded.
No playback of a CD :
Measure the voltage between the two ends of R2320 or R2322 on the DVDM
Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded.
If the measurements show degradation
of an LD, replace the PICKUP Assy.
displayed on the monitor
(The FL display lights. The
mechanism does not work.)
Check the voltage of AT+3.3V, –28V and FLDC on the POWER
SUPPLY Unit.
Are wires of output connector (POWER PCB ASSY) and CP4003
(DVDM Assy) disconnected or damaged ?
Check that the voltage at IC651-pin 10 (K 1) on the FLKY Assy
becomes about 2.7 V when the POWER key is pressed and 0 V when
it is released.
Check that the voltage at OS651-pin 1 (IR) on the OPERATION1 Assy
is in the range between 0 and 3.3 V while receiving signals from the
remote control unit when any key on it is pressed.
• Check the voltage of E+6.8 V and SW+3.3 V on the POWER PCB
ASSY.
• Check the voltage of P.ON-H is about 2.8 V on the POWER PCB
ASSY.

Assy fluctuating for one or two seconds after the power is turned ?
Check the video signal path between DVD IC (DVD MT Assy IC4001)
and video-out terminal (see the block diagram)
Does the voltage of CP2302-pin 3 and pin 1 on the DVD MT Assy
change normally ?
Pin 5 (SW2(TRIN)): Tray is fully closed: "L"
Pin 3 (SW1(TROUT)): Tray is fully opened: "L"
Is a LOAD-DRV signal reaching ?
Are the signals output from IC2301-pin 5 and pin 6 (CP2302-pin 4 and
pin 5) on the DVDMT Assy ?
Pin 5: Approx. 4.5 V during opening tray approx. 0V during closing tray.
Pin 4: Approx. 0V during opening tray approx. 4.5 V during closing tray.
Are wires of CP2302 and CP2303 on the DVDMT Assy disconnected
or damaged ?
Does the voltage of CP2303-pin 5 change by pressing the Inside
switch.
Are the signals output from IC2301-pin 9 (F+) and pin 8 (F–) on the
DVDMT Assy ?
Does 650-nm LD emit light ?
Does a pickup lens move up / down ?
Does an actuator spring bend ?
Are plastic parts damaged ? Or is a shaft detached ?
Is the turntable detached or tilted ?
Is flexible cable of CP2301 on the DVD MT Assy disconnected or
damaged ?
Is signal output from IC4001-pin 42 (FOSO) on the DVDMT Assy ?
(Device control of about 1.4 V is output usually. It is fluctuated by about
± 250 mV with focus up / down.)
Are the signals output from IC2301-pin 13 (MOT SPDL–), and pin 14
(MOT SPDL+) on the DVD MT Assy ?
Is pin 41, 42 (STBY) fixed LOW?
Is there any part detached from the spindle motor ?
Or Is there any foreign object lodged in it ?
Are wires of CP2303 on the DVD MT Assy disconnected or damaged ? Flexible cable / connector
Is signal output from IC4002-pin 37 (DMSO) on the DVDMT Assy ?
Does 650-nm LD deteriorate ?
If the voltage at each both ends of R2321 and R2323 on the DVD MT
Assy is 0.4 V or more, the 650-nm LD is definitely deteriorated.
Does 780-nm LD deteriorate ?
If the voltage at each both ends of R2320 and R2322 on the DVD MT
Assy is 0.4 V or more, the 780-nm LD is definitely deteriorated.
Are there scratches or dirt on the disc ?Disc
Are there scratches or dirt on the disc ?
