1. S AF ET Y INFORMATION
This service manual is intended for qualified service technici an s; 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 cove re d by this manual.
Improperly performed repairs can adversely affect the safety and re li ability 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
Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which
may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).
When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact wi th
the solder. Also, when soldering do not inhale any smoke or fumes produced.

IMPORTANT
THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUTED PERSON .
.--- LASER DIODE CHARACTERISTICS -
MAXIMUM OUTPUT POWER : 5 mw
WAVELENGTH: 780 - 785 nm
~---- Additional Laser Caution ------~
1. Laser Interlock Mechanism
The position of the switch (S902) for detecting loading
completion is detected by the system microprocessor,
and the design prevents laser diode oscillation when the
switch (S902) is not in CLMP terminal side (when the
mechanism is not clamped and CLMP signal is high
level.) Thus, the interlock will no longer function if the
switch (S902) is deliberately set to CLMP terminal side. (if
CLMP signal is l ow level).
In the test mode * the interlock mechanism will not
function.
Laser diode oscillation will continue, if pin 4 of TA2066F
(IC204) on the MOTHER board assy connected to GND,
or pin 19 is connected to high level (ON), or else the
terminals of 0206 are shorted to each other (fault
condition).
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a ~ass 1
laser beam .
*Refer to page 18.

4. PCB PARTS LIST
NOTES:
• Parts markedby "NSP" are generally unavailable because they are not in our MasterSpare Parts List.
• The 6 markfound on some componentparts indicates the importance of the safetyfactor of the part. Therefore, when replacing,
be sure to use parts of identicaldesignation.
• Parts markedby " ie) " are notalways kept in stock. Their delivery time may be longer than usual or they may be unavailable.
• When ordering resistors, first convert resistance values into codeform as shown in thefollowing examples.
Ex . 1 When there are 2 effective digits (any digitapartfrom 0), such as560 ohm and 47kohm (tolerance is shown by J = 5%,
andK= 10 %).

•Test Mode
Shows the function table of th e remote controller (RU-VlOl) for service as follows. Whenoperating the CD-ROM directly,
it is possible to operate as shown below byconnecting the wired-remote control' to the CD-ROM with the interface.
When the test commandis used, put in the shortsocketto MA, SL and GND pins of pinheader (C N751) on the re ar panel,
and turn the power on. (Refer to Fig. 2).

6.2 ADJUSTMENT METHODS
If a disc playeris adjusted incorrectly orinadequately, it may malfunction or notwork at all even though there is nothing
at all wrong with the pickup or the circuitry. Adjust correctly following the adjustment procedure.
• Adustment Items/Verification Items and Order
If the specified values cannot be obtained or no adjustment is possible by performing the verifications or adjustments
described in steps 1-3, the pickup block may be defective.
Step Item Test Point
1 Focus offset verification FO,
ERR(FE )
2 Tracking
error balance verification
TR,ERR(TE )
3
RF level adjustment (RF level) RF
Note : The digital servo IC (TC9406F) being us ed in this set has
the following functions and does not provide focus offset,
focus servo loop gain and tracking servo l:oop gain
adju stments.
1. Average Function
For accurate servo control, FO . ERR and RF average
measurements are performed and the measured values are
compensated through a compensation circuit.
Thus, volume control for Foucus offset adjustment is not
provided.
2. Auto Gain Control Function
The gaininside the filter is automatically adjusted to obtain a
propergainintheservo loop. Thisfunction permitstheoptimum
gain to be obtained on each disc.
Thus,volumecontrolsfor FO. GAIN and TR . GAIN adjustments
are not provided.
The gain adjustment is done before TOC reading.
•Measuring Instruments and Tools
