UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead-

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 viscous (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.

NOTES ON CHIP COMPONENT REPLACEMENT

• Never reuse a disconnected chip component.

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

aged 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.

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 radia-

tion exposure.

(When letters/numbers appear in the

display)

When the self-diagnosis function is activated to

prevent the system from malfunctioning, a 5-

character 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 following table.

When the version number

appears 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 operate.

SECTION 1

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro-

static 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.

How to open the disc table when power switch turns off

Insert a tapering driver into the aperture of the unit bottom, and

slide it in the direction of the arrow.

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 electric-

ity prevention solder bridge by unsoldering.

Remove the static electricity prevention solder bridge by unsolder-

ing after the ﬂexible printed circuit board has already been con-

nected.

(Do not remove nor unsolder the solder bridge as long as the OP

unit is kept standalone.)

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.

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.

IMPORTANT NOTICE

Caution: This system is capable of holding a still video image or on-

screen display image on your television screen indeﬁnitely. If you leave

the still video image or on-screen display image displayed on your TV

for an extended period of time you risk permanent damage to your tele-

vision screen.

Projection televisions are especially susceptible to this.

DISC TRAY LOCK

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/CD function.

3. Insert a disc.

4. Press the [x] button and the [Z] 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 [Z] button simultaneously for ﬁve

seconds again.

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

locked.

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

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

LASER DIODE AND FOCUS SEARCH

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

2. Conﬁrm that the following operation is performed while ob-

serving the objecting lens from the clearance of DVD mecha-

nism deck.

1) Conﬁrm that laser beam is spread.

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