1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-ityourselfer. 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 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 be of identical designation.

1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
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.

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.

5. PCB PARTS LIST

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

Turn on the power again after 2 - 3 minutes. Check the following connections : POWER SUPPLY Unit - DVDM Assy DVDM Assy - FLKY Assy FLKY Assy - PWSB Assy Check each voltage (EV+5V, SW+5V, SW+3.3V, +8V, +12V, -12V and -27V) (If above voltage are not supplied, check the micro-fuse.)

Is FL turn on ? Yes

Is the indication of FL normal ? Yes
FL indication is dark or flickers.
Short or open the zenner diode on the POWER SUPPLY Unit. (ZD102) Check the values of R118 on the FLKY Assy. Do not you set FL DIMMER ON ?

CONTROL IN/OUT jacks

Use to connect this player to another component bearing the Pioneer mark. This lets you control this unit as though it were a component in a system. Player operations are then performed by pointing the remote control at the component that the player is connect to.
COMPONENT VIDEO OUT switch
You only need to set this switch if youre using an NTSC TV/ monitor connected via the component video outputs of this player. This player can output NTSC video as a standard interlaced signal (the 525i(480i) setting), or as a non-interlaced, or progressive scan signal (the 525p(480p) setting). Generally, however, you should leave it set to MENU SELECT, which makes this setting switchable from the on-screen Setup menu. Switch manually if you have chosen a setting from the Setup menu that is incompatible with your television/monitor and therefore cant see any picture.
DIGITAL OUT jack (optical (OPT))
Use to output the digital audio signal recorded on discs. You can output the digital signal via either optical output jack to an AV amplifier or receiver.
COMPONENT VIDEO OUT jacks (Interlace/Progressive-scan)
If your TV or monitor has component video inputs, you can produce a higher quality picture on your TV or monitor by connecting to the component video outputs on this unit.

TOP MENU displays the top menu of a DVD disc. Joystick / ENTER button move the joystick up/down/left/right to navigate onscreen menus and displays; press to select menu items from the Setup menu and DVD disc menus. FL (DIMMER) changes the brightness of the front panel fluorescent display. Jog indicator lights when multi dial is in jog mode. JOG (JOG MODE) puts multi dial into jog mode. 8 (PAUSE) pauses/restarts playback. 1 (REV/FWD) press and hold for fast reverse/forward scanning. SEARCH MODE changes the disc search mode. C (CLEAR) clears a playlist entry; cancels repeat and random play modes. PROGRAM enters playlist programming mode. REPEAT A-B sets the repeat mode and loop points. CONDITION MEMORY memorizes the current player settings for the DVD disc loaded.
