PRODUCT SAFETY SERVICING GUIDELINES
FOR BLU-RAY DISC PLAYER PRODUCTS
IMPORTANT SAFETY NOTICE
this manual was prepared for use only by properly trained audio-video service
technicians.
When servicing this product, under no circumstances should the original design
be modified or altered without permission from Jvc. all components should be
replaced only with types identical to those in the original circuit and their physical
location, wiring and lead dress must conform to original layout upon completion of
repairs.
Special components are also used to prevent x-radiation, shock and fire hazard.
these components are indicated by the letter “x” included in their component des-
ignators and are required to maintain safe performance. no deviations are allowed
without prior approval by Jvc.
circuit diagrams may occasionally differ from the actual circuit used. this way,
implementation of the latest safety and performance improvement changes into the
set is not delayed until the new service literature is printed.
CAUTION
: do not attempt to modify this product in any way. never perform cus-
tomized installations without manufacturer’s approval. unauthorized modifications
will not only void the warranty, but may lead to property damage or user injury.
Service work should be performed only after you are thoroughly familiar with these
safety checks and servicing guidelines.
TIPS ON PROPER INSTALLATION
1. never install any receiver in a closed-in recess, cubbyhole, or closely fitting shelf
space over, or close to, a heat duct, or in the path of heated air flow.
2. avoid conditions of high humidity such as: outdoor patio installations where dew
is a factor, near steam radiators where steam leakage is a factor, etc.
3. avoid placement where draperies may obstruct venting. the customer should
also avoid the use of decorative scarves or other coverings that might obstruct
ventilation.
4. Wall- and shelf-mounted installations using a commercial mounting kit must
follow the factory-approved mounting instructions. a product mounted to a shelf
or platform must retain its original feet (or the equivalent thickness in spacers) to
provide adequate air flow across the bottom. Bolts or screws used for fasteners
must not touch any parts or wiring. Perform leakage tests on customized instal-
lations.
5. caution customers against mounting a product on a sloping shelf or in a tilted
position, unless the receiver is properly secured.
6. a product on a roll-about cart should be stable in its mounting to the cart.
caution the customer on the hazards of trying to roll a cart with small casters
across thresholds or deep pile carpets.
7. caution customers against using extension cords. explain that a forest of exten-
sions, sprouting from a single outlet, can lead to disastrous consequences to
home and family.

SERVICE INFORMATION
While servicing, use an isolation transformer for protection from ac line shock. after
the original service problem has been corrected, make a check of the following:
FIRE AND SHOCK HAZARD
1. Be sure that all components are positioned to avoid a possibility of adjacent
component shorts. this is especially important on items trans-ported to and from
the repair shop.
2. verify that all protective devices such as insulators, barriers, covers, shields,
strain reliefs, power supply cords, and other hardware have been reinstalled per
the original design. Be sure that the safety purpose of the polarized line plug has
not been defeated.
3. Soldering must be inspected to discover possible cold solder joints, solder
splashes, or sharp solder points. Be certain to remove all loose foreign par-
ticles.
4. check for physical evidence of damage or deterioration to parts and compo-
nents, for frayed leads or damaged insulation (including the ac cord), and
replace if necessary.
5. no lead or component should touch a high current device or a resistor rated at 1
watt or more. lead tension around protruding metal surfaces must be avoided.
6. after reassembly of the set, always perform an ac leakage test on all exposed
metallic parts of the cabinet (the channel selector knobs, antenna terminals,
handle and screws) to be sure that set is safe to operate without danger of
electrical shock. do not uSe a line iSolation tranSForMer durinG
thiS teSt. use an ac voltmeter having 5000 ohms per volt or more sensitivity
in the following manner: connect a 1500 ohm, 10 watt resistor, paralleled by a
.15 mfd 150v ac type capacitor between a known good earth ground water pipe,
conduit, etc.) and the exposed metallic parts, one at a time. Measure the ac volt-
age across the combination of 1500 ohm resistor and .15 mfd capacitor. reverse
the ac plug by using a non-polarized adaptor and repeat ac voltage measure-
ments for each exposed metallic part. voltage measured must not exceed 0.75
volts rMS. this corresponds to 0.5 milliamp ac. any value exceeding this limit
constitutes a potential shock hazard and must be corrected immediately.

SERVICING PRECAUTIONS
caution: Before servicing the Blu-ray diSc Player cov-
ered by this service data and its supplements and addends,
read and follow the SaFety PrecautionS. note: if
unforeseen circumstances create conflict between the follow-
ing servicing precautions and any of the safety precautions in
this publications, always follow the safety precautions.
remember Safety First :
General Servicing Precautions
1. always unplug the Blu-ray diSc Player ac power cord
from the ac power source before:
(1) removing or reinstalling any component, circuit board,
module, or any other assembly.
(2) disconnecting or reconnecting any internal electrical
plug or other electrical connection.
(3) connecting a test substitute in parallel with an electro-
lytic capacitor.
Caution
: a wrong part substitution or incorrect polar-
ity installation of electrolytic capacitors may result in an
explosion hazard.
2. do not spray chemicals on or near this Blu-ray diSc
Player or any of its assemblies.
3. unless specified otherwise in this service data, clean elec-
trical contacts by applying an appropriate contact cleaning
solution to the contacts with a pipe cleaner, cotton-tipped
swab, or comparable soft applicator.
unless specified otherwise in this service data, lubrication of
contacts is not required.
4. do not defeat any plug/socket B+ voltage interlocks with
whitch instruments covered by this service manual might be
equipped.
5. do not apply ac power to this Blu-ray diSc Player
and / or any of its electrical assemblies unless all solidstate
device heat sinks are correctly installed.
6. always connect the test instrument ground lead to an
appropriate ground before connecting the test instrument
positive lead. always remove the test instrument ground
lead last.
Insulation Checking Procedure
disconnect the attachment plug from the ac outlet and turn
the power on. connect an insulation resistance meter (500v)
to the blades of the attachment plug. the insulation resistance
between each blade of the attachment plug and accessible
conductive parts (note 1) should be more than 1Mohm.
Note 1
: accessible conductive Parts include Metal panels,
input terminals, earphone jacks,etc.
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged
easily by static electricity. Such components commonly are
called electrostatically Sensitive (eS) devices. examples of
typical eS devices are integrated circuits and some field effect
transistors and semiconductor chip components.
the following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1. immediately before handling any semiconductor compo-
nent or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known
earth ground. alternatively, obtain and wear a commercially
available discharging wrist strap device, which should be
removed for potential shock reasons prior to applying power
to the unit under test.
2. after removing an electrical assembly equipped with eS
devices, place the assembly on a conductive surface such
as aluminum foil, to prevent electrostatic charge buildup or
exposure of the assembly.
3. use only a grounded-tip soldering iron to solder or unsolder
eS devices.
4. use only an anti-static solder removal device. Some solder
removal devices not classified as “anti-static” can generate
electrical charges sufficient to damage eS devices.
5. do not use freon-propelled chemicals. these can generate
an electrical charge sufficient to damage eS devices.
6. do not remove a replacement eS device from its protective
package until immediately before you are ready to install
it. (Most replacement eS devices are packaged with leads
electrically shorted together by conductive foam, aluminum
foil,or comparable conductive material).
7. immediately before removing the protective material from
the leads of a replacement eS device, touch the protective
material to the chassis or circuit assembly into which the
device will be installed.
caution: Be sure no power is applied to the chassis or cir-
cuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged
replacement eS devices. (normally harmless motion such
as the brushing together of your clothes fabric or the lifting
of your foot from a carpeted floor can generate static elec-
tricity sufficient to damage an eS device.)
