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.
SECTION 1
SERVICING NOTES
SCD-XA333ES
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
pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objectiv e lens.
CLEANING OF OPTICAL PICK-UP LENS
In cleaning the lens of optical pick-up, use the air blower.
Never use a cotton swab for cleaning the lens of optical pick-up,
which otherwise causes a trouble.

TEST MODE
FLUORESCENT INDICATOR TUBE MODE
Procedure:
1. Press the [POWER] button while shorting the TP (TEST
MODE) on the DISPLA Y board, and turn on the po wer so that
the following operations will be executed automatically.
1 Grid of all segments lights up sequentially starting from 1G
to 16G.
2 The vertical line (total 5 lines) of all grids lights up sequen-
tially in the range of 3G to 16 G starting from the left.
3 The horizontal line of (total 7 lines) of all grids lights up
sequentially in the range of 3G to 16G starting from the top.
4 Grids from 5G to 6G go off.
2. With the machine in the status that is set in step 1-4, press
any on the remote commander. The grids 1G and 2G go off
and then the machine enters the key check standby state. (When
the [OPEN/CLOSE] key or the [ ] key is pressed, the reception check is canceled.)
x
3. After the key check is completed, turn JOG clockwise to turn
on the calendar segments sequentially . When the segment “20”
is confirmed, turn JOG counter-clockwise that turns off the
calendar segment. When the segment “1” is conf irmed, this is
the end of check.
4. After all the checks are completed, confirm to see that the display “!%%TEST-END!!%” appears. The message indicates
that the check is ended normally.
5. Press the
disconnect the power plug from the wall outlet.

lL
lL
to enter.
2. When “SET TEST START” is displayed, rotate the

lL
3. A checking will start automatically, and “0. IC&FL CHECK”
will be displayed. (Checking time is about 3 seconds)
4. After IC communication check, all segments of fluorescent
display tube will be lit. At this time, check visually for a skipped
character.
5. At successful completion of check, “0. IC CHECK OK” is
displayed. In this case, no error exists in the IC interface. Proceed to 4-2. AUTO CHECK.
Note: The check mentioned above tests the communication from micro-
computer to main ICs. Even if the check successfully finished, the
IC to be checked is not always normal. Consider it for reference
only.
6. In case of an IC communication error, the following display
will be given during the checking. Possible causes of error are
as listed below.
Error display Causes (typical example)
DVD DEC. ERROR 1. IC701 (SACD decoder) is faulty
DVD DRAM ERR 1. IC706 (D-RAM) is faulty

3. 768fs (33.86688 MHz) is not present to
IC701 pin <znm (XTAL)
• IC811 (3-multiplying circuit) is faulty
• Clock signal 256fs is not sent from
AUDIO board (CN902 pin 4)
• CN902 pin 1,5 (DFGND) and pin 3
(3.3V-D) are open or shorted
• CN902 and FFC connection is loose,
or FFC is disconnected
2. IC701 pin <znv (XRST) does not go “H”
• IC901 pin rf (XDIS) does not go “H”

• Data line, address line, WE, etc.
4. D903 (1SS367) is faulty
2. 768fs (33.86688 MHz) is not present to

Same as cause 3 of DVD DEC. ERROR
3. IC509 pin 2 (XRST) does not go “H”
• IC901 pin rf (XDIS) does not go “H”
• IC902 (expander) is faulty
Error display Causes (typical example)
PRAWN DRAM ERR 1. IC808 (D-RAM) is faulty
*1 2. IC801 (DSD decoder) is faulty
RF AMP ERROR 1. IC001 (RF AMP) is faulty
3. 768fs (33.86688 MHz) is not present to

RF) and pin wa (SDEN) must be checked
*1 DSD decoder is also checked.
Causes Common to Each IC:
1. Faulty communication line between microcomputer and each
IC.
Disconnected patterns, floating series resistors, bridge, etc.
2. Faulty IC supply voltage.
Particularly, check D+3.3V voltage. (D+5V for display microcomputer)
3. Faulty microcomputer communication port to each IC
Note: In case of more than two errors, the error display is switched over
one after another, thus making the reading difficult.
In such a case, press again the [ AMS ] dial to make a
recheck for error reading.

4-2. AUTO CHECK (AUTOMATIC VARIOUS MEASUREMENTS)
The auto check is performed to check if the set operates stably. Though a checking is made automatically, whether the measured data are
within the specification is evaluated by the service person. The auto check results in NG immediately, if the check itself causes an error.
Setting Method of Auto Check Mode:
1. After setting the test mode, rotate the [ AMS ] dial to select “92. SET CHECK” and press the [ AMS ] dial to enter.
2. When “SET TEST START” is displayed, rotate the [ AMS ] dial clockwise by 2 clicks to select “1. TOTAL CHECK?”
and press the [ AMS ] dial to enter.
lL
3. When “10. TOTAL CHECK” is displayed, rotate the [ AMS ] dial clockwise by 1 click to select “11. AUTO CHECK?”.
CD and SACD (SL) Disc Operation Check
Checking method:
1. Press the [OPEN/CLOSE] button to open the tray and place the test disc *1. The [OPEN/CLOSE] key is disabled immediately after the
machine enters the TEST mode. Be sure to initialize the table.
2. Press the [ AMS ] dial, and the following check will be performed automatically.
lL
3. Finally, the test disc will be ejected and the auto check will finish.
4. “AUTO CHECK OK” will be displayed at successful completion of auto check.
5. Recheck is enabled if the [ AMS ] dial is pressed in step 4. (Also, use this operation when exchanging the test disc)
lL
6. In case of an error during the checking, the check is interrupted automatically and the error is displayed. (Error display example:
“DISC DETECT ERROR”) After error display, “CONT?STOP (J/S)” is displayed. In this case, if the [ AMS ] dial is pressed,
the check where the error occurred is skipped and you can proceed to the next check. Also, if the x button is pressed, the check
finishes and “AUTO CHECK NG” is displayed when even one NG item exists.
*1 Use PATD-012 or YEDS-18 for CD, and SATD-S5 or SATD-S4 for SACD (SL). Using another disc will result in a checking failure.

the most inward trackymost outward track by the set number of
times or until an error occurs using the dual layer HD disc, DL
disc.
A set of operation including an access to the layer 0 (most inward
track)tlayer 0 (most outward track)t focus jump (layer
0t1)tlayer 1 (most outward track)t layer 1 (most inward

This test checks the auto adjustment time required when the disc
is switched between HD (SACD) layer and CD layer. This test is
conducted to check the stability in switching from CD to SACD,
or SACD to CD in the HYBRID disc.

of this set, the multiple discs can be placed. Even when the
discs (CD or the SACD SL disc) of different types are mixed,
the aging test can be performed. Use the [MULTI/2CH] key
when placing a disc. When discs are placed in positions, press
the [ AMS ] dial.
5. The aging test starts.
