Self-diagnosis Function 
(When letters/numbers appear in the 
display)
When the self-diagnosis function is activated 
to prevent the player from malfunctioning, a 
five-character service number (e.g., C 13 50) 
with a combination of a letter and four digits 
appears on the screen and the front panel 
display. In this case, check the following 
table.

have checked the inside 
of the rotary table and 
resolved any possible 
problems, press

To prevent a malfunction, the 
player has performed the

, Contact your nearest 
Sony dealer or local 
authorized Sony service 
facility and give the 5-

CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur-
ing 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  CHECK-OUT
After correcting the original service problem, perform the follow-
ing 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 pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable.  (See Fig. A)

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 oc-
cur 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.

Example of discs that the player 
cannot play
The player cannot play the following discs:
• All  CD-ROMs (including PHOTO CDs)/
CD-Rs/CD-RWs other than those recorded 
in the following formats:
–music CD format
–video CD format
–MP3 format that conforms to ISO9660*
Level 1/Level 2, or its extended format, 
Joliet
• Data part of CD-Extras
• DVD-ROMs
• DVD Audios
* A logical format of files and folders on CD-
ROMs defined by ISO (International Standards 
Organization).
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

• 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
• Note 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. Also, images in DVD-RWs  
with CPRM* protection may not be played if they 
contain a copy protection signal. “Copyright 
lock” appears on the screen. For more 
information, see the operating instructions for the 
recording device.
Note that discs created in the Packet Write format 
cannot be played.
* CPRM  (Content Protection for Recordable 
Media) is a coding technology that protects 
copyright for images.
