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. 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”

This checking must be performed before any other checking.

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 [PUSH

ENTER] (Used time : 7 sec) “FFFF” is displayed.

6. Turn “JOG DIAL” clockwise until “B1” and press the [PUSH

ENTER].
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 [PUSH

ENTER].
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.)

Use the following hybrid disc on this check.
HLXA-509 : PART No. J-6090-090-A
SACD HYBRID DISC (MARKET DISC)
Connection:

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.
