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 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

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 (waterpipe
, 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.
(FOR USA MODEL ONLY)

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

6. ADJUSTMENT
6.1 WHEN REPLACING 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.
WHEN REPLACING DVD DECK
[ Removing the DVD Deck ]
[ 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
Fig. 1
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.
