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

This appliance is classiﬁ ed 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 speciﬁ ed 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 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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the leadfree 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)

SAFETY-RELATED COMPONET 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.

: 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 viscous (sticky, less prone to ﬂ ow)

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.

Special Component Notice

The components identiﬁ ed by mark 9 contain conﬁ dential infor- mation. Strictly follow the instructions whenever the components are repaired and/or replaced.

SERVICING NOTES

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 ﬂ exible 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 reﬂ ective 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 case and turn POWER on with no disc inserted.

2. Conﬁ rm that the following operation is performed while observing the objecting lens from the clearance of DVD mechanism deck.

1) Conﬁ rm that laser beam is spread.

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

DISC TRAY LOCK

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

Setting Procedure :

1. Press the [

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

3. Insert a disc.

4. Press the [x] button and the [A] button simultaneously for ﬁ ve 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 ﬁ ve 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.

On cleaning discs, disc/lens cleaners

• Do not use cleaning discs or disc/lens cleaners (including wet or spray types). These may cause the apparatus to malfunction.

Self-diagnosis Function

HCD-DZ30

(When letters/numbers appear in the display)

When the self-diagn osis fu ncti onis 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 TV screen or front panel display. In this case, check the follo w ing table.

C:13:50

First 3 characters of the service number

C 13 The disc is dirty.

C 31 The disc is not inserted corr e ct ly.

E XX (xx is a number)

Cause and/or corrective action

Clean the disc with a soft cloth.

Restart thesystem, thenre-insert

the disc correctly.

To prevent a mal function, 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

When displaying the version number on the TV screen

When you turn on the system, the version number [VER.X .XX] (X is a number) may appear on the TV 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 operat e.

VER.X.XX

How to open the disc table when power switch turns off

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 ﬂ exible printed circuit board ﬁ rst of all before removing the static electricity prevention solder bridge by unsoldering. Remove the static electricity prevention solder bridge by unsoldering after the ﬂ exible printed circuit board has already been connected. (Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)
