SAFETY PRECATION

IMPORTANT SERVICE NOTES

ServiceManual

Note:

This Player can be used only where the power supply is
AC 230 V, 50 Hz. It cannot be used elsewhere.

CAUTION:

USE OF CONTROLS OR ADJUSTMENTS OR
PERFORMANCE OF PROCEDURES OTHER THAN
THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.

AS THE LASER BEAM USED IN THIS PLAYER IS
HARMFUL TO THE EYES, DO NOT ATTEMPT TO
DISASSEMBLE THE CABINET. REFER SERVICING
TO QUALIFIED PERSONNEL ONLY.

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS EQUIPMENT TO
RAIN OR MOISTURE.

TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, AND ANNOYING INTERFERENCE, USE THE
RECOMMENDED ACCESSORIES ONLY.

Power Cord Protection

To avoid any malfunctions of the Player, and to protect
against electric shock, fire or personal injury, please observe
the following.

• Hold the plug firmly when connecting or disconnecting the AC
power cord.

• Keep the AC power cord away from heating appliances.

• Never put any heavy object on the AC power cord.

• Do not attempt to repair or reconstruct the AC power cord in any
way.

• 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.

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.

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.

[3] IMPORTANT SERVICE NOTICE

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. When replacing the NOR Flash Memories for SIGMA (IC8503, IC8504), even if o ne of them is to be replaced, both types need to be replaced.
When replacing the Flash Memories, use ones with the same version.

3. The E2PROMs for SIGMA (IC7601) and (IC7602) cannot be replaced independently as a single part, because the system information needs to be
written. (The whole CBA needs to be replaced.)

4. After replacing the E2PROM for front-end software (IC2505), perform Menu - Miscellaneous Settings - Reset Settings.

[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 status changes from blinking DVD_LED (white) to blinking BD_LED (white) as “V-up” message keeps blinking on LCD.

5. When upgrading with the disc is completed, the Tray automatically opens.
* If the front-end software was upgraded, BD_LED (white) will blink ; then DVD_LED and BD_LED will turn blue, red, etc.; 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 LCD will display as follows:
(1) Upgrading successful:”V-End” will light.
(2) Upgrading unsuccessful: “V-Err” will light.

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.
* If the upgrading was unsuccessful, perform the procedure again from the step 1.

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

9. Switch to [Main Diagnostic Menu] using [F4] button of the special remote control for servicing.

10.Looking at the version numbers in SIGMA Ver. and FRONT Ver., confirm that the upgrading to the desired version was completed.

11.Quit [Main Diagnostic Menu] by pressing [Green] button of the remote control.

12.Press [Power] button to turn the power off. (Confirm the power-off by stop of the cooling fan.)
