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.

WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to

B

cause cancer, birth defects or other reproductive harm. Health & Safety Code Section 25249.6 – Proposition 65

NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation.

REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que

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

D

E

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 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.

Reading should not be above

0.5 mA

Earth ground

Device under test

Also test with plug reversed (Using AC adapter plug as required)

Test all exposed metal surfaces

Leakage current tester

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

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 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.

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 additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

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%).

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

Cautions:

Because there is not a Spacer for height adjustment in adjustment after the second time, will keep it at need. (This parts is Traverse mechanism exclusive use of a model for 2001 years)

Entering the ID Number and ID Data for Players with DVD-Audio and DVD-RW Compatibility

To enter the input mode, press ESC + STEREO in a status with no ID number set, such as after FLASH-ROM downloading.

• Downloading FLASH-ROM is finished. (The latest version must be downloaded when a repair is made.)

• "No ID Number" is displayed on the screen or FL display immediately after the power is turned on or in Stop mode.

• If "No ID DATA" is displayed, the ID data must be entered.

Important: If no yellow label is found on the rear panel, write down the specified ID number by checking it according to "How to confirm the ID number" shown below.

Note:

Be sure to enter the ID number in Stop mode. Use the service remote control (GGF1067) for operations. Only opening/closing of the tray are performed from the player. Use Disc No. : GGV1084

It is necessary with a player with DVD-audio and DVD-RW compatibility to set an individual number (ID number) and ID data. If the number and data are not set correctly with the following procedure, operations in the future may not be guaranteed. You will find the ID number to be set on the yellow label on the rear panel.

Indication of the mechanism error history and self diagnosis result refer to "7.1.1 self diagnosis function".

4 Error information indication of the AV decoder

(a) When a retry occurred in reading from the disc, a history indicates the occurrence location and the occurrence reason. History is indicated to past seven times. Eight columns of the beginning show the physical address which occurred of retry. As for four columns of next, bitmap indicates EDC status. LSB shows the first sector during a block and MSB shows a last sector. Following field indicates the retry number of times. One digit in front of " / " shows number of times of the retry by EDC Error which occurred in the same block in succession.

One digit after " / " shows number of times of the retry by ID Check Error which occurred in the same block in succession. " * " of last one digit shows the EDC Check NG Count Over. " # " shows the ID Check NG Count Over. When " * " and " # " are not indicated, show that data were rightly readable by retry process. (b) Indicate the error information that detected with the Audio/Video Decoder. When error occurred, a history indicates the occurrence time and the occurrence reason. History is indicated to past seven times. Field in front of ":" indicates the error information of Audio/Video Decoder. (Indication information is different from Fujitsu Decoder with Mitsubishi Decoder) 02 model is 656 series and 757 series is Mitsubishi model.

Command Busy (XCBUSY) was in force for 200 µS during continuous coefficient writing, or before and after a continuous write command was issued to DSP.

In the backup sequence, codes could not be read for fixed time. Stops

Cannot close tracking even if performs backup fixed number of times. Stops

During tracing, do not restore after the runaway detection backup was performed several times.

During playback, the overcurrent detection port was at L for 300 ms or more continuously.

After the overcurrent detection (C3 error), furthermore the overcurrent detection port was at L for 300 mS or more continuously.

The tray switch that had been Open mode was forcibly changed to a mode other than Open by an external force.

Loading or unloading could not be completed within a specified time (about 10 seconds). Though a portable cover is opening, when a close command was issued from the system controller.

• Focus ON sequence could not be completed more than two seconds.

• Auto sequence command was finished, actually focus ON was not completed.

• Focus did not enter even if retried it eight times.

Causes if with a DVD Causes if with a CD Operation of the Unit

Subcode could not be read within 1 second after the tracking on.

(PH code nothing) When Philips code is not readable during LD starting, and a code was not readable after the slider moved to FWD and REV directions slowly each for five seconds. (PRD) In the CD starting, when a subcode of TOC part was not readable, but the subcode of the program area was readable.

Opens (Subcode readout failure).

Stops

Stops (the mechanical controller operates independently).

Turns off the power instantly (No indication on the FL display and no writing to flash memory)

Closes

Search, scan and special playback prohibition, Playback as playback CD-R (PRD mode) as it is.

Reverses the loading direction. It timeout is repeated upon retry, the unit stops.

Stops wherever possible then opens (stops in the case of side B).
