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.
First three
characters of
the service
number
Cause and/or corrective
action
C 13 The disc is dirty.
,Clean the disc with a soft
cloth.
C 31 The disc is not inserted
correctly.
,Re-insert the disc
correctly.
C 32 The front cover
automatically opens and the
player enters standby mode.
,Check that there is
nothing wrong inside the
rotary table, such as a
fallen disc. After you
have checked the inside
of the rotary table and
resolved any possible
problems, press H.
E XX
(xx is a number) Toprevent a malfunction, the player has performed the
self-diagnosis function.
,Contact your nearest
Sony dealer or local
authorized Sony service
facility and give the 5-
character service number.
Example: E 61 10

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. Measuringthe voltagedrop across aresistor bymeans ofaVOM
or battery-operatedAC 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 2VAC 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.

Following Discs
“DVD VIDEO” and “DVD-RW” are
trademarks.
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
identicalregion 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.

SERVICING NOTES
The laser diode in the optical pick-up block may suffer electro-
static 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 emis-
sion, observe from more than 30 cm away from the objective lens.
NOTE OF REPLACING THE MB BOARD
When replacing the MB board, since the adjustment value is not
set up correctly, “Drive Auto Adjustment” can’t be performed.
In this case, initialize Memory in the following procedures.
Procedure:
1. Set the test mode. (See page 23)
2. Press the [2] key of the remote commander, and set the“DRIVE
MANUAL OPERATION”. (See page 29)
3. Press the [6] key of the remote commander, and set the “2-6,
Memory Check”. (See page 32)
4. Press the [CLEAR] key of the remote commander, and initial-
ize Memory.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
CHECK OF POWER BOARD WITH THE POWER ON
It is possible to analyze the defect with only POWER board power
ON.
Procedure:
1. Set to power OFF state.
2. Remove the connector from CN201 on the POWER board.
3. Short between CN201 pin 1(P-CONT) and CN201 pin qa
(EVER+3.3V) on the POWER board.
4. Turn the power ON.
5. Confirm that the voltage value of CN201 each pin on the
POWER board satisfy following value .
CN201 Pin Voltage Value
pin 2(EVER–11V) –11V
pin 3(SW–11V) –11V
pin 6, 7(SW+11V) +11V
pin 8(SW+3.3V) +3.3V
