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 pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.
This appliance is
classified as a CLASS 1
LASER product. This
label is located on the
rear exterior.

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and check
that the S curve waveform is output three times.
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 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 manufactur ers’ instructions to use these
instruments.
2. A battery-operated A C 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 v oltmeter. The “limit” indication
is 0.75 V, so analog meters must hav e 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 A C range are suitable. (See
Fig. A)

HOW TO OPEN THE DISC TRAY WHEN POWER
SWITCH TURNS OFF
Insert a tapering driver into the aperture of the unit bottom, and turn
in the direction of arrow.
Use a flat (-) head screwdriver to open the disc tray by manual
operation. (Flat head screwdriver with nominal blade length of
3mm.)
* To close the disc table, turn the driver in the reverse direction.

TEST MODE
1. Setting Methed of Test Mode
Press three buttons m , [PUSH ENTER] and [POWER] simulta-
neously, The test mode becomes active. Then all segments of the
fluorecent indicator tube are turned on.
2. FL Tube Grid, Segments Check
Procedure:
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 sequentially
in the range of 5G 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 5G to 16G starting from the top.
3. Sircs Receive Check
Procedure:
1. The message “SIRCS CHECK” is displayed on the fluorecent
indicator tube.
2. With the machine in the status that is set in step 2, press any
on the remote commander. The machine enters the ke y check
standby state. (When the H key or the x key is pressed,
the reception check is canceled.)
4. Key Check
Procedure:
1. In the key check mode, the fluorecent indicator displays “KEY
CHECK**”. Each time a button is pressed, “**” value.
However, once a button is pressed, it is no longer taken into
account.
2. To exit from this mode, the message “JOG CHECK” is
displayed.
5. Jog Check
Procedure:
1. After the key check is completed, turn JOG clockwise to tur n
on the calendar segments sequentially . When the segment “15”
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.
6. Releasing Meted of Test Mode
1. After all the checks are completed, confirm to see that the
display “TEST-END” appears. The message indicates that
the check is ended normally.
2. Press the [POWER] button to turn off the main power and
disconnect the power plug from the wall outlet.

GENERAL DESCRIPTION
After parts to the circuit (OPTICAL PICK-UP (DBU-3), RF
BOARD, MAIN BOARD, EEPROM (IC702), MASTERCOM
(IC705), DSP (IC706), so on) are replaced, readjusting is necessary.
1. ROM Version Check
Procedure:
1. While pressing [PUSH ENTER] button and [MENU] buttons,
press the [POWER] button to turn the set on.
“DIAG MODE” is displayed on the screen.
2. Select “81 SYS-F VER” by tuning l AMS L knob.
3. Press [PUSH ENTER] button.
4. Check the version of ROM.
“SYS. VER X.XX” is displayed.
5. Select “82 I/F-F VER”
“I/F VER X.XX” is displayed.
Automatically return “81 SYS-F VER”
2. U-CON Check (The system version number is Ver
1.24 and higher)
This checking must be performed before any other checking.
CHECK DISC LIST
Use the following disc on this check.
SATD-S4: PART No. J-2501-184-A
SATD-S5: PART No. J-2501-215-A
Procedure:
1. While pressing [PUSH ENTER] button and [MENU] buttons,
press the [POWER] button to turn the set on.
“DIAG MODE” is displayed on the screen.
2. Push the Z button to open the tray.
3. Load CD to tray.
4. Push the Z button to close the tray.
5. Turn “JOG DIAL” clockwise until “B0” and press the [PUSHENTER] (Used time : 7 sec) “FFFF” is displayed.
6. Turn “JOG DIAL” clockwise until “B1” and press the [PUSHENTER].
Display shows “-9” and the numbering is counting down until
“-0” lastly, “****” (4 DIGITS VALUE) appears. (Used time :
33 sec)
7. Turn “JOG DIAL” clockwise until “B2” and press the [PUSHENTER].
Display shows the last number that appear at. STEP NO.7.
Confirm that the value is “08D0”>THE VALUE>“04D0”
8. Push the Z button to open the tray.
9. Unload CD from tray.
10. Push the Z button to close the tray.
11. Press the [POWER] button to turn the set off. (Do not continue
with another test mode without power off.)
3. Optical Sensitivity Check
CHECK DISC LIST
Use the following hybrid disc on this check.
HLXA-509 : PART No. J-6090-090-A
SACD HYBRID DISC (MARKET DISC)
Connection:
oscilloscope
MAIN board
CN702 (PIN27)
CN702 (PIN31)
+
–
Procedure:
1. Press the Z button.
2. Insert SACD hybrid disc (market disc).
3. Connect the oscilloscope to pin 27 and pin31 of CN702.
4. Observe the MIRR waveform immediately after the disc
chucking is completed when disc identification is made.
MIRR signal wavefor m
T
1V/DIV, 5ms/DIV
5. Read the measurement of ∆ T.
IF 7.5ms <∆ T<9.7ms> OK
OTHERS>NG
6. When the system version number is before ver.1.24, and if the
MIRR waveform is NG (No Good), change the values of R892
and R893, and then repeat step4 and after.
4. Mode Setting For Shipping (MAIN board on EEPROM
(IC702) is replaced.)
Be sure to set the unit to the specified modes as stated in the steps
below after sampling inspections by the QA dept.
Or before shipping.
Procedure:
1. While pressing [PUSH ENTER] and [MENU] buttons, press the
[POWER] button to turn the set on.
“DIAG MODE” is displayed in the screen.
2. Turn jog until the specified mode (According to version) is
displayed:
a) “8D SETUP” : CEL
b) “8F SETUP” : U & OTHERS
3. Press jog one single time.
“INIT START” is displayed and Mode setting for shipping
starts.
4. Wait until “INITIAL OK” appears on the display.
5. By this operation, the unit is initialized as follows:
PLAY MODEALL DISCS
COMMAND MODECD 1
REPEATOFF
SACD/CDSACD

6. After 2 to 3 sec., Press the [POWER] button to turn the set off.
Note : When EEPROM (IC702) is replaced, the initialization
is necessary.
