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 manufactur ers’ 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 v oltmeter. The “limit” indication
is 0.75 V, so analog meters must hav e 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

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 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.

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.

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.

SECTION 1

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.

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 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.

Note on MAIN board replacement

New part of EEP ROM (IC1103) on the MAIN board cannot be used.
Therefore, if the mounted MAIN board (A-1144-739-A, etc.) is replaced,

exchange new EEP ROM (IC1103) with that used before the replacement.

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.

%%

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.)

Be sure to use the DVD disc that matches the signal standards of
your region.

• CD YEDS-18 (Part No.: 3-702-101-01)

PATD-012 (Part No.: 4-225-203-01)

• DVD SL (Single Layer)

Procedure:

1. Connect an oscilloscope to CN1105 pin 6 (RFMON) and
CN1105 pin 3 (GND) on the MAIN board.

2. Turn the power on.

3. Insert the CD test disc (refer to the TEST DISC LIST), and
press the H button to play the disc back.

4. Confirm that oscilloscope waveform is clear and check RF
signal level is correct or not.

Note: A clear RF signal waveform means that the shape “◊” can be

clearly distinguished at the center of the waveform.

5. Eject the CD disc, and insert the DVD SL test disk (refer to
the TEST DISC LIST), and press the H button to play the
disc back.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)

For Schematic Diagrams.
Note:

• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except f or electrolytics and
tantalums.

• All resistors are in Ω and 1/
specified.

• f : internal component.

• C : panel designation.

Note:

The components identi­fied by mark 0 or dot­ted line with mark 0 are
critical for safety.
Replace only with part
number specified.

✩ New part of EEP ROM (IC1103) on the MAIN board

cannot be used. Therefore, if the mounted MAIN board
(A-1144-739-A, etc.) is replaced, exchange new EEP
ROM (IC1103) with that used before the replacement.

• A : B+ Line.

•Voltages and wav ef orms 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 v ariations ma y be noted due to normal production
tolerances.
no mark : DVD STOP
* : Impossible to measure

•Voltages are taken with VOM (Input impedance 10 MΩ).

• Circled numbers refer to waveforms.
