SECTION 1
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.
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.

4-1. IC AND FLUORESCENT DISPLAY TUBE CHECK
(SELF-DIAGNOSIS)
The communication between microcomputer and main ICs (self-
diagnosis) and the fluorescent display tube all lit are checked.
Checking Method:
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 1 click to select “0. IC&FL
CHECK?” and press the [ AMS ] dial to enter.

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. Pro-
ceed 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)

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 mi-
crocomputer)
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.

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.
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.
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)
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 xbutton is pressed, the check
finishes and “AUTO CHECK NG” is displayed when even one NG item exists.
*1 Use PATD-012 orYEDS-18 for CD, and SATD-S5 or SATD-S4 for SACD (SL). Using another disc will result in a checking failure.
