1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and ser vice 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 (waterpipe , conduit, etc.) by connecting a leakage current tester
D
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. 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.
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
NOTES:
A
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 56 x 10 1 RD1/4PU 5 6 1 J 561 47k RD1/4PU 4 7 3 J 47 x 10 3 473 0.5 RN2H R 5 0 K R50 1 RS1P 1 R 0 K 1R0 Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x 10 1 5621 RN1/4PC 5 6 2 1 F

A
WHEN REPLACING DVD DECK
[ Removing the DVD Deck ] Before removing Pick Up PCB and DVD PCB connector, short circuit the position shown in Fig. 1 using a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged.
[ Installing the DVD Deck ] Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD PCB connector. NOTE · Before your operation, please read "PREPARATION OF SERVICING" . · Use the Lead Free solder. · Manual soldering conditions · Soldering temperature: 320 ± 20°C · Soldering time: Within 3 seconds · Soldering combination: Sn-3.0Ag-0.5Cu · When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the Flux smoke from it.

The laser diode used for a pickup head may be destroyed with external static electricity. Moreover, even if it is operating normally after repair, when static electricity discharge is received at the time of repair, the life of the product may be shortened. Please perform the following measure against static electricity, be careful of destruction of a laser diode at the time of repair. · Place the unit on a workstation equipped to protect against static electricity, such as conductive mat. · Soldering iron with ground wire or ceramic type is used. · A worker needs to use a ground conductive wrist strap for body.

7.1.5 METHOD FOR DIAGNOSING DEGRADATION OF THE LDS ON THE PICKUP ASSY
Case when this diagnosis is required : When playback of any disc, including a test disc (DVD: GGV1025, CD: STD-905), cannot be performed
A
How to diagnose
In the case mentioned above, degradation of the laser diodes (LDs) mounted on the PICKUP Assy is suspected. Measure the voltage between the two ends of one of the resistors mentioned below.
No playback of a DVD :
Measure the voltage between the two ends of R2321 or R2323 on the DVDM Assy. If the voltage is 0.4 V or higher, the 650-nm LD is degraded. If the measurements show degradation of an LD, replace the PICKUP Assy.
No playback of a CD :
Measure the voltage between the two ends of R2320 or R2322 on the DVDM Assy. If the voltage is 0.4 V or higher, the 780-nm LD is degraded.
