SAFETY PRECAUTION
IMPORTANT SERVICE NOTES
IMPORTANT SERVICE NOTES
This Player is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT label is located on
the rear cover.
This product contains a low power laser device. To
ensure continued safety do not remove any cover or
attempt to gain access to the inside of the product.
Refer all servicing to qualified personnel.

IMPORTANT SERVICE SAFETY PRECAUTION
WARNING
1. For continued safety, no modification of any circuit should be
attempted.
2. Disconnect AC power before servicing.
BEFORE RETURNING THE BD PLAYER (Fire &
Shock Hazard)
Before returning the BD player to the user, perform the following
safety checks:
3. Inspect all lead dress to make certain that leads are not pinched,
and check that hardware is not lodged between the chassis and
other metal parts in the receiver.
4. Inspect all protective devices such as non-metallic control knobs,
insulation materials, cabinet backs, adjustment and compartment
covers or shields, isolation resistor-capacitor networks, mechanical
insulators, etc.
5. To be sure that no shock hazard exists, check for leakage current in
the following manner.
Plug the AC cord directly into a 120 volt AC outlet.
Using two clip leads, connect a 1.5k ohm, 10 watt resistor paral-
leled by a 0.15 F capacitor in series with all exposed metal cabinet
parts and a known earth ground, such as electrical conduit or elec-
trical ground connected to an earth ground.
Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-
sitivity or measure the AC voltage drop across the resistor.
Connect the resistor connection to all exposed metal parts having a
return to the chassis (antenna, metal cabinet, screw heads, knobs
and control shafts, escutcheon, etc.) and measure the AC voltage
drop across the resistor.
All checks must be repeated with the AC cord plug connection
reversed. (If necessary, a nonpolarized adaptor plug must be used
only for the purpose of completing these checks.)
Any reading of 0.75 Vrms (this corresponds to 0.5 mA rms AC.) or
more is excessive and indicates a potential shock hazard which
must be corrected before returning the monitor to the owner.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
SAFETY NOTICE
Many electrical and mechanical parts in BD player television have
special safety-related characteristics.
These characteristics are often not evident from visual inspection, nor
can protection afforded by them be necessarily increased by using
replacement components rated for higher voltage, wattage, etc.
Replacement parts which have these special safety characteristics are
identified in this manual; electrical components having such features
are identified by " " and shaded areas in the Replacement Parts List
and Schematic Diagrams.
For continued protection, replacement parts must be identical to those
used in the original circuit.
The use of a substitute replacement parts which do not have the same
safety characteristics as the factory recommended replacement parts
shown in this service manual, may create shock, fire or other hazards.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the
servicing guidelines which follow:
CAUTION: FOR CONT I N U ED PROTECTION
AGAINST A RISK OF FIRE REPLACE ONLY WITH
SAME TYPE FUSE.

Precautions for using lead-free solder
Employing lead-free solder
• “All PWBs” of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals.
The alphabetical character following LF shows the type of lead-free solder.
Example:
Using lead-free wire solder
• When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause dam-
age or accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a dedicated soldering
bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40 °C, and as it has poor
solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be
peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the
steady soldering condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as
required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
• Be careful when replacing parts with polarity indication on the PWB silk.

and take the procedure again starting from [1] above.
7. Remove the disc from the Tray and press any other button of the Main Unit than [Power], then the Tray will close and the power will automatically
turn off. (Confirm the power-off by stop of the Cooling Fan.)
* If [Power] button is pressed, the power will turn off with the Tray open.
8. Press [Power] button to turn the power on, then wait till the MODE INDICATOR changes from blinking to lit.
9. Press the [SETUP] button on the remote controller, and the menu screen shows up (if the wallpaper screen is used).
* There is no need to take this step, because just after the power is turned on, the menu screen shows up.
10.Select [SETTINGS] first and then [VERSION]. (Press the ENTER button.)
11.The version of the currently installed software appears on the monitor screen. Compare with the version of this updated software, make sure the
version is just the same. If the version id not updated, take the procedure again from Step [2].
12.Press [Power] button to turn the power off. (Confirm the power-off by stop of the cooling fan.)
NOTE: Do not unplug the AC cord during version updating.
* The version updating cannot be made on the menu screen. Make the wallpaper onscreen.
