SAFETY CHECK-OUT (US Model)

After correcting the original service problem, perform the follow­ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs,
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA

WT-540A. Follow the manufacturers’ instructions to use these
instruments.

2. A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a

VOM or battery-operated AC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
Fig. A)

To Exposed Metal
Parts on Set

Except US, Canadian Model

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 radia-
tion 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)

: 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.

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 TV screen or 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.

E XX

(XX is a
number)

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.

Cause and/or corrective action

,Clean the disc with a soft cloth

(page 63).

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.

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 ob-
serving 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 [Z] 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 [Z] 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

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 on­screen display image on your television screen indefi nitely. 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 tele­vision screen.
Projection televisions are especially susceptible to this.

When installing a new OP unit, be sure to connect the fl exible
printed circuit board fi rst of all before removing the static electric-
ity prevention solder bridge by unsoldering.
Remove the static electricity prevention solder bridge by unsolder­ing after the fl exible 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.)

When the optical pick-up assy is replaced, perform the “EXECUT­ING IOP MEASUREMENT”.

EXECUTING IOP MEASUREMENT (See page 21)

TUNER SECTION

generator

SET

Procedure:

1. Turn the power on.

2. Input the following signal from Signal Generator to FM an­tenna input directly.

FM ANTENNA

OUT (75 :)

* Carrier Freq : A = 87.5 MHz, B = 98 MHz, C = 108 MHz
Deviation : 75 kHz
Modulation : 1 kHz
ANT input : 35 dBu (EMF)

Note: Please use 75 ohm “coaxial cable” to connect SG and the set. You

cannot use video cable for checking.

Please use SG whose output impedance is 75 ohm.

3. Set to FM tuner function and tune A, B and C signals.

4. Confi rm “TUNED” is lit on the display for A, B and C signals.

The mark of “TUNED” means “The selected station signal is re­ceived in good condition.”

• A : B+ Line.

• B : B– Line.

• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

• Voltages and waveforms are dc with respect to ground in
service mode.

• Waveforms are taken with a oscilloscope.

Voltage variations may be noted due to normal production

tolerances.
