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

SERVICING NOTES
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 pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
NOTES ON REPLACEMENT OF THE MB BOARD
1. Flash Memory
New part of flash memory (IC202) on the MB board cannot be
used. Therefore, if the mounted MB board (A-1132-163-A) is
replaced, exchange new flash memory with that used before the
replacement.
2. Adjustment
When replacing the MB board, since the adjustment value is not set
up correctly, "Drive Auto Adjustment" in the Test Mode can't be
performed.
In this case, initialize memory in the following procedures.
Procedure:
1. Connect a video monitor to VIDEO LINE OUT jack (J103).
2. Press the [TOP MENU], [CLEAR], I/1 keys on the remote
commander (RM-ASP001) in this order with standby status
to enter the Test Mode, then "DIAG START" will be displayed
on the fluorescent indicator tube and the Test Mode Menu
screen will be displayed on the monitor.
3. Press the [2] key on the remote commander to select the "2.
Drive Manual Operation".
4. Press the [6] key on the remote commander to select the "6.
Memory Check".
5. Press the [CLEAR] key on the remote commander to initialize
the memory.
Note: Refer to page 22 for detail of the Test Mode.

Region code
Your player has a region code printed on the
back of the unit and will only play DVD
VIDEOs (playback only) labeled with
identical region codes. This system is used to
protect copyrights.
DVD VIDEOs labeled
will also play on
this player.
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 labeled even though
playing the DVD VIDEO is prohibited by
area restrictions.
Example of discs that the player
cannot play
The player cannot play the following discs:
·CD-ROMs/CD-Rs/CD-RWs other than
those recorded in the format listed on the
previous page.
·Data part of CD-Extras
·DVD-ROMs
·DVD Audios
Also, the player cannot play the following
discs:
·A DVD VIDEO with a different region
code.
·A disc recorded in a color system other than
NTSC, such as PAL or SECAM (this player
conforms to the NTSC color system).
·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.
·DVD-Rs recorded in VR mode (Video
Recording format)
·Copy-Once programs recorded on CPRM*
compatible DVD-Rs.

Notes
· Notes about DVD+RWs/DVD+Rs, DVD-RWs/
DVD-Rs or CD-Rs/CD-RWs
Some DVD+RWs/DVD+Rs, DVD-RWs/DVD-
Rs or CD-Rs/CD-RWs cannot be played on this
player 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 created
in Packet Write format cannot be played.
·Music discs encoded with copyright protection
technologies
This product is designed to playback 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 playback operations of
DVDs and VIDEO CDs
Some playback operations of DVDs and
VIDEO CDs may be intentionally set by
software producers. Since this player plays
DVDs and VIDEO CDs according to the disc
contents the software producers designed,
some playback features may not be available.
Also, refer to the instructions supplied with
the DVDs or VIDEO CDs.
