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 :
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.
General Servicing Precautions
1.Always unplug the BLU-RAY DISC PLAYER AC power cord 1.
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- 2.
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 sotidstate
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.
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.
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-propetled 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.)

1-1. Lines on Picture
Distorted picture refers to the customer getting video, but there is a problem with the video.

YES
Has the customer tried
another set of cables?
Determine what cables the customer is using to connect
the BD to the TV and if connected properly. Refer to OM for
connections. Tighten any loose cables. Make sure the customer
is not connecting a BD to VCR or BD to DVD Recorder.
Copy protection can distort the picture on older DVD models.
Make sure the TV is on the correct input.
Turn TV off, then on to determine input.
Video when using composite, or component.
DVl when using DVl, and HDMI when using HDMI.
One disc displaying the issue is a problem with the disc.
Multiple discs displaying the problem could indicate the BD lens
needs to be cleaned. Recommend the customer use a lens
cleaner on the BD. A lens cleaner is available at any local
electronics retailer.
Lines appearing when watching a TV program indicates
an issue with the display. If the TV program is fine,
then connect the BD to another input on the display to
determine if the problem is following the BD.
Connect the BD to another TV and play a disc.
No lines during disc play back indicates a problem with the first TV.
Please refer to the owners manual for instructions on how to
connect the BD to a TV. If the BD has a problem on the
second TV, then see service chart for service information.
Have the customer try another set of cables. A bad cable can
also cause video problems. Test the cable with another device to
the TV to also determine if the TV is bad. If BD is problem,
please see service chart for service information.
