SAFETY PRECAUTION

IMPORTANT SERVICE NOTES

IMPORTANT SERVICE NOTES

Service Manual

• 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

Service work should be performed only by qualified service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow:

BD-HP17U

WARNING

1. For continued safety, no modification of any circuit should be attempted.

2. Disconnect AC power before servicing.

CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE FUSE.

F901 (250V 3.15A)

Use an AC voltmeter having with 5000 ohm per volt, or higher, sensitivity 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.

DVM

BEFORE RETURNING THE BD PLAYER (Fire &

Shock Hazard)

Before returning the BD player to the user, perform the following safety checks:

Inspect all lead dress to make certain that leads are not pinched,

3. and check that hardware is not lodged between the chassis and other metal

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.

o be sure that no shock hazard exists, check for leakage current in

5. T 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 paralleled by a 0.15 F capacitor in series with all exposed metal cabinet parts and a known earth ground, such as electrical conduit or electrical ground connected to an earth ground.

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.

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:

L Fa

Indicates lead-free solder of tin, silver and copper.

L F a/a

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 damage 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.

1. To replace the Main CBA, perform the items 9 - 12 of [4] Upgrading and confirm the version: it is necessary to upgrade with a disc to the latest version if the CBA version is old.

2. The IC7201 and IC8505 cannot be replaced because they have the BD-playback key already written. Accordingly, the IC8502 that has the software written together with the IC8505 cannot be replaced either. Keep also in mind that the IC8503 cannot be replaced either because of the model information on it.

[4] UPGRADING

Consult with your Services Company as we cannot provide the upgrading software.

1. Press [Power] button to turn the switch on, then wait till the BD_LED changes from blinking to lit.

2. Press [Tray Open/Close] button to open the Tray, put the upgrade disc on the tray and close the tray.

3. The power automatically turns off. Then it turns on again and the upgrading with the disc will start.

4. During the upgrading, the mode indicator stays blinking in white as “V-up” message keeps blinking on LCD.

“NOW UPDATING DO NOT UNPLUG AC CORD” appears on the monitor screen.

And the version updating progress is expressed in %.

5. When upgrading with the disc is completed, the Tray automatically opens.

* If the front-end software was upgraded, the standby LED lights up halfway as well as the mode indicator starts blinking alternately in white and

blue.; the Tray will open after the upgrading is completed and the power will turn off. (Go to step 8.)

6. When the upgrading is completed, the following appears on the monitor screen.:

“SOFTWARE UPDATE IS COMPLETE”

If the version updating fails, “FAILED TO COMPLETE UPDATE RETRY SOFTWARE UPDATE” is displayed. Take out the disc, turn off the power 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).
