This service manual is intended for qualified service technicians; it is not
meant for the casual do-it-yourselfer. Qualified technicians have the neces-
sary 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
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 with the solder. Also, when soldering do not inhale
any smoke or fumes produced.
1. SAFETY INFORMATION
(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
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or
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 60Hz outlet and turn the AC power switch on. Any
current measured must not exceed 0.5mA.
A Reading should
Ceakage | Not be above
current | 0-5mA
Device
under
test
Test ail
exposed metal
surfaces
2-wire cord
Also test with
plug reversed
(Using AC adapter ground
plug as required)
©
ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO-
TENTIAL SHOCK HAZARD AND MUST BE COR-
RECTED BEFORE RETURNING THE APPLIANCE TO
THE CUSTOMER. :
2.PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the appli-
ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob-
tained by using replacement components rated for vol-
tage, 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 A on the schematics and
on the parts list in this Service Manual.
The use of a substitute replacement component which
dose 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 ad-
ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S 601) for the detecting
loading completion is detected by the system
microprocessor, and the design prevents laser diode
oscillation when the switch (S 601) 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
(S601) is deliberately set to CLMP terminal side (if
CLMP signal is low level).
In the test mode, the interlock mechanism will not
function (refer to page 36).
Laser diode oscillation will continue if pins 2 and 3 of
CXA 1471S (IC 101) are connected to ground or pin
20 is connected to high level(ON) or the terminals of Q
101 are shorted to each other(fault condition).

e How to install the disc table
[1] Use nippers or other tool to cut the two sections
marked @ in figure (1]. Then remove the spacer.
[2] While supporting the spindle motor shaft with
the stopper, put spacer on top of the motor base
(angled so it doesn’t touch section ®), and stick
the disc table on top (takes about 9kg pressure).
Take off the spacer.
