Design and specifications are subject to change without notice.

Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

This appliance is classified as a CLASS 1 LASER product. This marking is located on the rear or bottom exterior.

CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 °C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

• Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.

• Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

SERVICING NOTE

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

LASER DIODE AND FOCUS SEARCH

1. Open the cover and turn POWER on with no disc inserted.

2. Confirm that the following operation is performed while observing the objecting lens.

1) Confirm that laser beam is spread.

2) Up and down motion of the objective lens. (3 times)

DISC TRA Y LOCK

The disc tray lock function for the antitheft of an demonstration disc in the store is equipped.

Setting Procedure :

1. Press the ?/1 button to turn the set on.

2. Press the [FUNCTION] button to set DVD function.

3. Insert a disc.

4. Press the

x button and the A button simultaneously for five

seconds.

5. The message “LOCKED” is displayed and the tray is locked.

Releasing Procedure :

1. Press the x button and the A button simultaneously for fiv e seconds again.

2. The message “UNLOCKED” is displayed and the tray is unlocked.

Note : When “LOCKED” is displayed, the tray lock is not released by

turning power on/off with the ?/1 button.

Self-diagnosis Function

(When letters/numbers appear in the display)

When the self-diagnosis function is activated to prevent the system from malfunctioning, a 5character service number (e.g., C 13 50) with a combination of a letter and 4 digits appears on the screen and the front panel display. In this case, check the following table.

C:13:50

First 3 characters of the service number

C 13 The disc is dirty.

C 31 The disc is not inserted correctly.

E XX (xx is a number)

When displaying the version number on the screen

When you turn on the system, the version number [VER.X.XX] (X is a number) may appear on the screen. Although this is not a malfunction and for Sony service use only, normal system operation will not be possible. Turn off the system, and then turn on the system again to operate.

Cause and/or corrective action

,Clean the disc with a soft cloth

,Restart the system, then re-insert

the disc correctly.

To prevent a malfunction, the system has performed the selfdiagnosis function.

,Contact your nearest Sony

dealer or local authorized Sony service facility and give the 5character service number.

Example: E 61 10

Note on DMB12 board replacement

New part of EEP ROM (IC103, IC706) on the DMB12 board cannot be used. Therefore, if the mounted DMB12 board (A-1166-695-A, A-1166728-A) is replaced, exchange new EEP ROM (IC103, IC706) with that used

before the replacement.

PRECAUTION WHEN INSTALLING A NEW OP UNIT / PRECAUTION BEFORE UNSOLDERING THE STATIC ELECTRICITY PREVENTION SOLDER BRIDGE

When installing a new OP unit, be sure to connect the flexible printed circuit board first of all before removing the static electricity prevention solder bridge by unsoldering. Remove the static electricity prevention solder bridge by unsoldering after the flexible printed circuit board has already been connected. (Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)

TEST MODE

HCD-DZ820KW

Ver. 1.1

Note 1: Regarding the notification symbol “R”

Because the number of the operating buttons of this product are limited, some operations require use of the operating buttons of the remote commander, When a specific operation requires use of the operating buttons of the remote commander, “R” is added to the specific operating procedure in this manual. Example MENU/NO “R” The MENU/NO button of remote commander.

Note 2: Incorrect operations may be performed if the test mode is

not entered properly. In this case, press the ?/1 button to turn the po wer of f, and retry to enter the test mode.

1. Cold Reset
