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.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

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 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 A C voltmeter . The “limit” indication
is 0.75 V, so analog meters must have an accurate low-v oltage
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)

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

HCD-HDX500/HDX501W

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)

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.
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 operate.

SERVICING NOTES

HCD-HDX500/HDX501W

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.

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.

NOTE OF REPLACING THE EEPROM (IC1103) ON
THE MAIN BOARD

EEPROM (IC1103) on the MAIN board cannot exchange with
single. When EEPROM (IC1103) on the MAIN board is dama ged,
exchange the entire mounted board.

RELEASING THE TRAY LOCK

• CD-ROMs recorded in PHOTO CD format

• Data part of CD-Extras

• DVD Audios

• Super Audio CD

• DATA DVDs that do not contain MP3 audio

tracks or JPEG image files

• DVD-RAMs

Also, the system cannot play the following
discs:

• A DVD VIDEO with a different region code

• A disc that has a non-standard shape (e.g.,

card, heart)

• A disc with paper or stickers on it

• A disc that has the adhesive of cellophane tape

or a sticker still left on it

Notes about CD-R/CD-RW/DVD-R/
DVD-RW/DVD+R/DVD+RW

In some cases, CD-R/CD-RW/DVD-R/DVD­RW/DVD+R/DVD+RW cannot be played on
this system due to the recording quality or
physical condition of the disc, or the
characteristics of the recording device and
authoring software.
The disc will not play if it has not been correctly
finalized. For more information, see the
operating instructions for the recording device.
Note that some playback functions may not
work with some DVD+RWs/DVD+Rs, even if
they have been correctly finalized. In this case,
view the disc by normal playback. Also some
DATA CDs/DATA DVDs created in Packet
Write format cannot be played.

Music discs encoded with
copyright protection
technologies

This product is designed to play back discs that
conform to the Compact Disc (CD) standard.
Recently, various music discs encoded with
copyright protection technologies are marketed
by some record companies. Please be aware that
among those discs, there are some that do not
conform to the CD standard and may not be
playable by this product.

Note on DualDiscs

A DualDisc is a two sided disc product which
mates DVD recorded material on one side with
digital audio material on the other side.
However, since the audio material side does not
conform to the Compact Disc (CD) standard,
playback on this product is not guaranteed.

About Multi Session CD

• This system can play Multi Session CDs when
an MP3 audio track is contained in the first
session. Any subsequent MP3 audio tracks
recorded in later sessions can also be played
back.

• This system can play Multi Session CDs when
a JPEG image file is contained in the first
session. Any subsequent JPEG image files
recorded in later sessions can also be played
back.

• If audio tracks and images in music CD format
or video CD format are recorded in the first
session, only the first session will be played
back.

Region code

Your system has a region code printed on the
rear of the unit and will only play DVDs labeled
with the same region code.

DVD VIDEOs labeled will also play on this

ALL

system.
If you try to play any other DVD VIDEO, the
message [Playback prohibited by area
limitations.] will appear on the TV screen.
Depending on the DVD VIDEO, no region code
indication may be given even though playing the
DVD VIDEO is prohibited by area restrictions.

Note about playback
operations of DVDs and
VIDEO CDs

Some playback operations of DVDs and VIDEO
CDs may be intentionally set by software
producers. Since this system plays DVDs and
VIDEO CDs according to the disc contents the
software producers designed, some playback
features may not be available. Be sure to read the
operating instructions supplied with the DVDs
or VIDEO CDs.
