1. SAFETY INFORMATION
This service manual is intended for qualified service technicians; 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 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.
IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 7 mw WAVELENGTH: 780 785 nm
LABEL CHECK PD-F1007/MY
Additional Laser Caution
1. Laser Interlock Mechanism The position of the switch (VSK1011) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (VSK1011) is not on CLMP terminal side (CLMP signal is OFF or high level). Thus, the interlock will no longer function if the switch (VSK1011) is deliberatery set to CLMP terminal side. (low level) The interlock also does not function in the test mode *. Laser diode oscillation will continue, if pin 33 of CXA1782CQ (IC151) on the MOTHER BOARD ASSY is connected to GND, or pin 89 of IC351 (LDON) is connected to low level (ON), or else the terminals of Q151 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 Class 1 laser beam.

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%). 561 560 56 x 101 RD1/4PU 5 6 1 J 47 x 103 473 47k RD1/4PU 4 7 3 J R50 0.5 RN2H R 5 0 K 1R0 1 RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x 101 5621 RN1/4PC 5 6 2 1 F

Step 1: Connect all equipment as shown in the diagram. Step 2: Turn on the power of the CD player. Put the test disc in the no. 1 disc slot. Step 3: Turn the test mode on. Step 4: Press the MODE key. Step 5: Turn the VR601 on the VOLUME BOARD ASSY until the meter on the Digital Multi Meter reads 800± 5mV. Step 6: Turn off the power of the CD player. Step 7: Switch the connector that goes from the Digital Multi Meter to the Jig from input to output. Step 8: Turn on the power of the CD player. Step 9: Press the OPEN/CLOSE key twice. The 300 CD rack will spin around once. Step 10: While the test disc is spinning around(A section), press the switch on the jig and look at the Digital Multi Meter and record the number it is registering. After the CD rack has made a full rotation it will continue on slightly and return to the starting position. A second number will appear on the Digital Multi Meter, but you can ignore this number. If the number that appears on the meter while the rack is moving (the first number) is the important one. If it is between 900-1150 mV you can stop the process, no correction is necessary. Step 11: Switch the connection input between the Digital Multi Meter and the Jig back to input. Step 12: Turn the test mode on. Step 13: Press the MODE key. Step 14: Turn the VR601 on the VOLUME BOARD ASSY to match the first number on the Digital Multi Meter with the chart provided below.
Step 15: Do steps 6-10 again. In step 10, the number that appears on the Digital Multi Meter should be between 900-1150 mV. If it is you have completed the correction.

1. Detection of the rack position
There are two types of slits on the rear of the rack, and their combination is used to find which disc has been selected during rack rotation. The input ports (DCNT, DPOS) are as follows.

· When the position of the selection mechanism just before switching to disc selection operation os DCNT terminal = "L". (Normally, DCNT terminal = "H" exists when the selection mechanism is stopped, so that it can be assumed that the position of the mechanism has deviated for some reason. There is the possibility that a position deviation of the mechanism can cause a defect of the mechanism.) · At the time of movement of the selection mechanism, a deviation has occurred between the present position of the disc and the disc position according to position detection. (It can be assumed that the waveform at the DCNT terminal and/or at the DPOS terminal has been miscounted. When a miscount occurs, a discrepancy occurs between the displayed disc No. and the counted disc position.) · When the position of the mechanism became DCNT terminal = "L" during disc loading. (Normally, DCNT terminal = "H" exists when the selection mechanism is stopped, so that it can be assumed that the position of the mechanism has deviated for some reason. There is the possibility that a position deviation of the mechanism can cause a defect of the mechanism.) · At the time of shifting to a different disc after play completion, the pickup does not return to the innermost circumference.

3-1 In Regard to the Disc Detection Method Disc detection is performed after stabilization of the rotation speed after rack rotation start and completion of acceleration. (After start of rotation, detection starts after feed of 20 discs.) The input ports DCNT and DISC of the microcomputer are used for disc detection. Port Explanation : DCNT : As described above. DISC : Input of the disc detection result by the photocell for disc detection. Input value "H" : No disc, "L" : Disc present 3-2 In Regard to the Disc Detection Timing

Relation between input port DCNT, DPOS and position of the mechanism
2. Position relation between position of the rack mechanism and photocell for disc detection
The relation between these two positions is as follows.
1 The microcomputer looks every 1 msec at the status (H or L) of the two inputs DCNT and DISC. 2 8 msec (A in the figure) after the drop of DCNT (C in the figure), the last 17 DISC inputs (B in the figure) are checked. A disc is assumed to be resent when even one of them is "L". 3 No disc is assumed when DISC was "H" all 17 times (B in the figure) in 2. ) of DCNT Note: In regard to the drop ( For looking at the drop or rise of DCNT, it is necessary to check DCNT every 1 msec for "H" or "L". ). "H" = "L" means a drop ( "L" = "H" means a rise ( ). For the timing, either one of the following A and B can be assumed. Accordingly, the point where a drop is found differs by max. 1 msec for A and B. Thus, using the above figure, it can be said that the time from finding that a drop has occurred until starting to check for disc presence (A in the above figure) becomes 8 to 9 msec.
Position of the mechanism
Photocell for detection
Fig.: The rack seen from above The position of the mechanism and the photocell for detection are offset by a distance corresponding to 9 discs. Accordingly, the photocell for detection sees the disc number 9 discs before the position of the mechanism. Example: Disc No. at the rack position : Disc No. 100 Disc No. seen by the photocell for detection : Disc No. 91 Note: The rack has 307 slits, but the slits 301 to 303 and 304 to 307 are the space for the side of the single loader and are not used. Disc detection also is not performed for them.
