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.
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.
The CLASS 1 LASER
PRODUCT MARKING is
located on the rear exterior.
The following caution label is located inside the apparatus.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED
LINE WITH MARK 0 ON THE SCHEMATIC DIA GRAMS
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.

SERVICING NOTES
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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
Carry out the “S curve check” in “CD section adjustment” and
check that the S curve waveforms is output three times.
• RELEASING THE DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Releasing Procedure :
Press two buttons of Z (CD) and [GROOVE] sim ultaneously for
five seconds. The message “UNLOCKED” is displayed and the
tray is unlocked.

[GC TEST MODE]
•This mode is used to check the software version, FL tube, LED,
keyboard and VACS.
Procedure:
1. Press three buttons [ ], [DISPLAY], and [EFFECT] simulta-
neously.
2. LEDs and fluorescent indicator tube are all turned on.
3. When you want to enter the software version display mode,
press [GROOVE] . The model number and destination are displayed.
4. Each time [GROOVE] is pressed, the display changes stating
from MC version, GC version, DP version, CD version,
CDDM, CDMA, CDMB, BDA, BDB, ST version, TA version,
TM version, TC version, in this order , and returns to the model
number and destination display.
5. When [CD SYNC HI-DUB] is pressed while the version num-
bers are being displayed except model number and destination, year, month and day of the software creation appear. When [CD SYNC HI-DUB] is pressed again, the display
returns to the software version display. When [GROOVE] is
pressed while year, month and day of the software creation
are being displayed, the year, month and day of creation of the
software versions are displayed in the same order of version
display.
6. Press [EFFECT] button, and the key check mode is acti v ated .
7. In the key check mode, the fluorescent indicator tube displays
“K22 V0 C T”. Each time a button is pressed, “K” value decreases.
However, once a button is pressed, it is no longer taken into
account.
“V” value increases like 1, 2, 3...if rotating [VOLUME] knob
in the clockwise, or it decreases like 0, 9, 8...if rotating in the
counterclockwise.
Each time the “CD DOOR LOCK DETECT” or “CD DOOR

Volume check:
1. When the [VOLUME] knob is turned clockwise even slightly,
the sound volume increases to its maximum and a message
“VOLUME MAX” appears for two seconds, then the display
returns to the original display.
2. When the [VOLUME] knob is tuned counterclockwise even
slightly, the sound volume decreases to its minimum and a
message “VOLUME MIN” appears for two seconds, then the
display returns to the original display.

Procedure :
1. Connect an oscilloscope to TP (TEO) and TP (DVC).
2. Turn the power ON.
3. Load a disc (LUV-P01) and playback the number nine track.
4. Press the hH button. (Becomes the 1 track jump mode.)
5. Confirm that the level B and A (DC v oltage) on the oscilloscope
waveform.

6. After check, remove the lead wire connected in step 2.
Note: •Try to measure several times to make sure than the ratio
of A : B or B : A is more than 10 : 7.
•Take sweep time as long as possible and light up the
brightness to obtain best waveform.

Procedure :
1. Connect an oscilloscope CH1 to TP (RFDC) and CH2 to TP
(RF AC).
2. Turn the power ON.
3. Load a disc (LUV-P01) and playback.
4. Confirm that oscilloscope waveform is clear and check if RF
signal level is correct or not.

6. Adjust RV101 on the BD board so that the center of wav eform
becomes the same voltage of DVC. (i.e. A=0V)
