SAFETY CHECK-OUT

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 manuf acturers’ instructions to use these
instruments.

2. A battery-operated A C 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 v oltmeter . 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 A C range are suitable. (See
Fig. A)

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.

HCD-SV2D

Ver. 1.1

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.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear 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.

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 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.

• Abbreviation
E3 : 240 V AC area in E model.
SP : Singapore model.
TH : Thai model.

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 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 OPERATION
CHECK

Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveforms is output three times.

DISC TRA Y LOCK

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

Procedure :

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

2. Press the DVD u button to select “DVD”

3. Set disc on the tray, press the x button and the Z button
simultaneously for five seconds.

4. The message “LOCKED” is displayed the tray is locked.

TEST MODE

HCD-SV2D

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. W hen 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 power off, and
retry to enter the test mode.

COLD RESET

• The cold reset clears all data including preset data stored in
the RAM to initial conditions. Execute this mode when
returning the set to the customers.

Procedure:

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

2. Press three buttons x , [PLAY MODE] and DVD u simul-
taneously.

3. The message “COLD RESET” is displayed and the set is reset.

TUNER STEP CHANGE
(EXCEPT FOR AEP, UK, RUSSIAN models)

•A step of AM channels can be changed over between 9 kHz
and 10 kHz.

Procedure:

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

2. Select the function “TUNER”, and press [TUNER/BAND]
button to select the BAND “AM”.

3. Press the ?/1 button to turn the set OFF.

4. Press the x and [TUNER/BAND] buttons simultaneously,
and thus the channel step is changed over.

ELECTRICAL ADJUSTMENTS

Precaution

1. Clean the following parts with a denatured alcohol-moistened
swab:

record/playback heads pinch rollers
erase head rubber belts
capstan idlers

2. Demagnetize the record/playback head with a head demag­netizer.

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, apply suitable locking compound to
the parts adjusted.

5. The adjustments should be performed with the rated power
