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.
AC Leakage Test
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 Aon 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.

5. PCB PARTS LIST

NOTES: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 codeform as shown in the following examples.
Ex.l When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J-5%,
andK=:10%).

• Test Mode
This model has a test mode so that the adjustments and checks required for service can be carried out easily. When this model is 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 this model, all adjustments are carried out in test mode.
[ Setting to Test Mode ]
Howto set this model into test mode. (1 ) Unplug the power cord from the AC socket. (2) Short the test mode short land. (See Fig. 1.) (3) Plug the power cord back 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. (lights up all FL display) If the display is still the same as usual, test mode has not been set correctly, so repeat Steps 1 - 3.
[ 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.

Explanation
Pressing this key when the focus servo and spindie 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. If the elapsed time is not displayed or not counted correctly, it may be that something is our 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.
Moves the pickup position toward the inner diameter of the disc. When this key is pressed with the tracking servo in a closed loop, the tracking servo automatically goes into an open loop. Since the motor does not automatically stop at the mechanical end point in test mode, be careful with this operation.

continue turning the screwdriver, the amplitude of the wave becomes smaller again. Turn the screwdriver counterclockwise
from the null point and set the grating to the first point where the wave amplitude reaches its maximum.
Reference : Fig. 4 shows the relation between the angle of the tracking beam with the track and the waveform.
(5) Return the pickup to more or less midway across disc with the MANUAL / TRACK SEARCH ◄◄ key, press the
PAUSE II key and check that the track number and elapsed time are displayed on the front panel. If they are not displayed
at this time or the elapsed time changes Irregularly, check the null point and adjust the grating again.

Adjustment 1
[ How to find the null point ]
When you insert the small screwdriver into the slit for the grating adjustment and change the grating angle, the amplitude of the tracking error signal at CN104 (TP1), Pin 3 (TE) 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 right above the same track. (See Fig. 4.) This point is called the null point. When adjusting the grating, this null point is found and used as the reference position.

The communication timing is control by the mechanism
control CPU. 13 byte data is transmitted every 13.33 to 40
ms. (Average:13.33 msec)
86
Conununication is performed by the following procedure. © The MREQ signal becomes L as communication request
from the mechanism control microprocessor.
® This microprocessor sets the MACK signal to L as commu
nication enable signal.
© The mechanism controller sets the MREQ signal to H
after 1 byte serial transmission.
® This microprocessor sets MACK to H if serial transmis
sion has ended normally.
© Hereafter © to © are repeated until the 13 byte data
transmission has completed.
^ The mechanism controller and mode controller observes
the state of the other side’s control line, and stops cormnu-
nication processing of transmission if conditions are not
satisfied after a certain time.

(4) Communication with digital interface LSI
(LC89585, IC301)
Communication format
Communication with the digital interface LSI is performed using four lines. XFUSE is set to L during communication so that there are no clashes with the mechanism controller.
• FSI/FSO .. Serial data transmission line
• BLREQ ... Data enable
• XFUSE.... L when the mode controller is using the
communication line
Communication is performed in one main routine. The communication timing is controlled by the mode controller.
No transmission is performed during communication between
the mechanism controller and LC89585.
