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

1. SAFETY INFORMATION
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.
Reading should

SAFETY PRECAUTIONS -=SSSSSCANY MEASUREMENTS NOT WITHIN THE UM |
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 replacernent component which
dose not have the same safety characteristics as the
PIONEER recommended replacement one, shown in
the parts list in this Service Manua!, 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 consw't 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.

@ Notes
1. Use a 10:1 probe for the oscilloscope.
2. All the knob positions (settings) for the oscilloscope in the adjustment procedures are for when a 10:1 probe is
used.
@ Test mode
These models have a test mode so that the adjustments and checks required for service can be carried out easily.
When these models are in test mode, the keys on the front panel work differently from normal. Adjustments and
checks can be carried out by operating these keys with the correct procedure. For these models, all adjustments are
carried out in test mode.
[Setting these models to test mode}
How to set this model into test mode.
1. Unplug the power cord fror: the AC socket.
2. Short the test mode jumper .:ires. (See Figure 1.)
3. Plug the power cord hack into the AC socket.
When the test mode is set correctly, the display is different from what it usually is when the power is turned on. If
the display is still the same as usual, test mode has not been set correctly, so repeat Steps 1 — 3.
2s
[Release from test mode]
Here is the procedure for releasing the test mode:
1. Press the STOP key and stop all operations.
2. Unplug the power cord from the AC socket.

PAUSE Tracking servo
, close/open
The laser diode ‘is lit up and the focus actuator is
lowered, then raised slowly and the focus servo is closed
at the point where the objective lens is focused on the
disc.
With the player in this state, if you lightly rotate the
stopped disc by hand, you can hear the sound the focus
servo.
If you can hear this sound, the focus servo is operating
correctly. If you press this key with no disc mounted, the
laser diode lights up, the focus actuator is pulled down,
then the actuator is raised and lowered twice and
returned to its origina! position.
Starts the spindle motor in the clockwise direction and
when the disc rotation reaches the prescribed speed
(about 500 rpm at the inner periphery), sets the spindle
servo in a closed loop.
Be careful. Pressing this key when there is no disc
mounted makes the spindle motor run at the maximum
speed.
If the focus servo does not go correctly into a closed loop
or the laser light shines on the mirror section at the
outermost periphery of the disc, the same symptom is
occurred.
Pressing this key when the focus servo and spindle servo
are operating correctly in closed loops puts the tracking
servo into a closed loop, displays the track number being
played back and the elapsed time on the front panel, and
outputs the playback signal.
If the elapsed time is not displayed or not counted
correctly or the audio is not played back correctly, it may
be that the laser is shining on the section with no sound
recorded at the outer edge of the disc, that something is
out of adjustment, or that there is some other problem.
This key is a toggle key and open/close the tracking
servo alternately. This key has no effect if no disc is
mounted.

[How to play back a disc in test mode]
In test mode, since the servos operate independently, playing back a disc requires that you operate the keys in the
correct order to close the servos.
Here is the key operation sequence for playing back a disc in test mode.
PGM Lights up the laser diode and closes the focus servo.

[How
to
find
the
null
point}
@ Objective To align the tracking error generation laser beam spots to the optimum angle on the track. When you insert the regular screwdriver into the slit for the grating adjustment and change the grating angle, the
amplitude of the tracking error signal at TP1, Pin 2 changes. Within the range for the grating, there are five or six
locations where the amplitude of the wave reaches a minimum. Of these five or six locations, there is only one at which
the envelope of the waveform is smooth. This location is where the three laser beams divided by the grating are all nght
above the same track. (See Figure 3.)
This point is called the null point. When adjusting the grating, this null point is found and used as the reference position.

[Procedure]
1. Move the pickup to the outer edge of the disc with the MANUAL SEARCH FWD DD or REV <kikey.
2. Press the PROGRAM key, then the PLAY > key in that order to close the focus servo then the spindle servo.
3. Insert an ordinary screwdriver into the grating adjustment slit and adjust the grating to find the null point. For more
details, see the next page.
4. If you slowly turn the screwdriver clockwise from the null point, the amplitude of the wave gradually increases,
then if you continue turning the screwdriver, the amplitude of the wave becomes smaller again. Turn the
screwdriver clockwise from the null point and set the grating to the first point where the wave amplitude
reaches its maximum.
Reference : Figure 3 shows the relation between the angle of the tracking beam with the track and the waveform.
Null point
Figure 3
Note : The amplitude of the tracking error signal is about 3 Vp-p (when a 39 kQ+ 0.001 u F low pass filter is
used). If this amplitude is extremely small (2 Vp-p or less), the objective lens or the pickup malfunction
may be the cause. If the difference between the amplitude of the error signal at the innermost edge and
outermost edge of the disc is more than 10%, the grating is not adjusted to the optimum point, so adjust it
again.
. Return the pickup to more or less midway across the disc with the MANUAL SEARCH REV <k key, press the
PAUSE itt key and double check that the track number and elapsed time are displayed on the front panel. If they are
