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.

Additional Laser Caution
1. Loading-status detection switch (S101 on the LOAB assy) are detected
by the microprocessor (IC601 in the DVDM assy).
• To permit the laser diode to oscillate, it is required to set the loadingstatus detection switch for the clamp position (the center terminal of
S101 is shorted to +3V).
When the voltage of IC101-pin 21 is +3V, IC601 (microprocessor)
-pin 83 is +3V and IC601-pin 84 is +3V, 650nm laser diode for DVD
oscillates in the DVDM Assy.
When the voltage of IC101-pin 21 is +3V, IC601 (microprocessor)
-pin 83 is 0V (GND) and IC601-pin 84 is +3V, 780nm laser diode for
CD oscillates in the DVDM Assy.
In the test mode * , the laser diode oscillates when microprocessor
detects a PLAY signal, or when the PLAY key is pressed (S9043 ON in
the KEYB assy), with the above requirements satisfied.

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 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=5%,
and K=10%).
560 Ω
47k Ω
0.5 Ω
1 Ω
56 x 10
47 x 10
R50
1R0

3
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω

7.1.6 ERROR HISTORY
How to display the error history
A
Use the dedicated remote control unit for service.
Press the ESC then CHP/TIM keys. The measured error rate value, results of self-diagnosis, and time data read from the
real-time clock are displayed on the screen, as shown below:
Press the CHP/TIM key again to display the detailed information of the error history and results of self-diagnosis.
In the example below, the part enclosed with the solid line ( ) is the error history, and the part enclosed with the
dotted line ( ) is the results of self-diagnosis. (For details on the results of self-diagnosis, see "Self-diagnosis.")
B
C
Example:
How to translate the indications of the error history
The 2-digit hexadecimal number (F8, C3 or F8, in the above example) represents an error code, and the subsequent time
indication (000123:45, 000079:41, or 000052:17, in the above example) represents the accumulated power-on time when
a respective error was generated. The 2-digit number following the time indication is the number of times the respective
error was generated. As to an error that was generated consecutively several times, the time indication is that for the last
one. The bottom two lines are used for indicating the meaning of the latest error.
In the above example,
• An F8 error (loading error) was generated twice consecutively, and the accumulated power-on time upon generation of the
D
second F8 error was 52 hours 17 minutes.
• Then a new error (C3: detection of the tracking excess current) was generated consecutively three times, and the
accumulated power-on time upon generation of the last C3 error was 79 hours 41 minutes.
•A new F8 error (loading error) was generated at 123 hours 45 minutes.
Specifications of storage of the error history
If the same error is consecutively generated, as shown in the above example, the error counter counts the number of times
it was generated, and the last generation time is stored in memory (as shown with the first F8 error generated twice).
If another type of error is generated, its error code and time of generation are separately stored in memory. If that error is
generated consecutively several times, the error counter counts the number of times it was generated, and the latest
generation time is stored in memory (as shown with the second C3 error generated three times). Then if any error other
than C3 is generated, its error code and time of generation are separately stored in memory, even if the same error code
E
(F8 error, in the above example) already exists in the error history.
A maximum of 16 logs of errors can be recorded. The maximum count of generations per log is 255. In the above example,
3 logs are recorded (nonconsecutive F8 errors that were generated for the first and third times are counted as two errors.)
If the error count exceeds 16, the oldest error will be erased each time a new error is added.
As the maximum number of errors that can be displayed on one page is 8, if the number of errors is 9 or more, switch
between Page 1 (No. 1-8 logs) and Page 2 (No. 9-16 logs) by pressing the CHP/TIM key.

How to clear data of the error history
The data of the error history can be cleared by issuing the "EE0016EC" RS-232C command.
How to copy data of the error history to a USB memory device
The data of the error history can be copied to a USB memory device, using SAVE ERROR LOG in the ADV.SETUP menu.
Filename : The filename is the serial number of the product (excluding two characters that represent the destination), and
its extension is err.
File format : Text
Content of the file : The following data are recorded:
1 Serial number of the product
2 Accumulated power-on and playback time when copying to a USB memory device is performed
