2. PRODUCT SAFETY NOTICE
(FOR USA MODEL ONLY)
1. SAFETY PRECAUTIONS
LEAKAGE CURRENT CHECK
AC Leakage Test
The following check should be performed for the
continued protection of the customer and service
technician.
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 120 V
AC 60 Hz outlet and turn the AC power switch on.
Anycurrent measured must not exceed 0.5 mA.
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.
ANY MEASUREMENTS NOT WITHIN THE
LIMITS OUTLINED ABOVE ARE INDICATIVE
OF A POTENTIAL SHOCK HAZARD AND
MUST BE CORRECTED BEFORE RETURN-
ING THE APPLIANCE TO THE CUSTOMER.

8 There should be no semi-broken wires, scratches, melting, etc.on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure
connections and suitable usage. Please exchange the power cord if necessary.
aSafe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper
cleaning should be performed to restore their performances.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
5. Shipping mode and Shipping screws
To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be

1. SERVICE PRECAUTIONS
1.1 NOTES ON SOLDERING
1.2 NOTES SPECIFIC TO THIS PRODUCT
• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit.
Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs
accompanied by reworking of soldering.
• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of
the soldering iron.
Do NOT use a soldering iron whose tip temperature cannot be controlled.
Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting
temperatures (hard to melt/easy to harden).
The following lead-free solders are available as service parts:
• Parts numbers of lead-free solder:
GYP1006 1.0 in dia.
GYP1007 0.6 in dia.
GYP1008 0.3 in dia.
• The high-gloss resin parts of the exterior of this product are easily scratched. During disassembly and reassembly of this
product, be careful not to scratch the exterior.
• If the door of this product is pressed firmly from the front or when the KEY Assy and LED Assy are reassembled, print of the
front-panel operating section may be transferred to the inside surface of the door. To avoid this, be sure to attach the protect
film to the inside surface of the door before repairing. If protect film is not available, slip a cleaning cloth or the like inside the
door for protection.
• Remove the attached protect film after product installation is completed. If the repaired product is to be delivered to the
customer’ s home or a dealer, leave the protect film attached.
For tightening the screws for the HDMI connector and system cable connector, do not use an electric screwdriver. Tighten
them manually. If they are tightened too forcefully with an electric screwdriver, the screw heads may be damaged, in which
case the screws cannot be loosened/tightened any more.
