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 objective lens.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Noticethattheminus side of atantalumcapacitormay be damaged
by heat.
Flexible Circuit Board Repairing
•Keep the temperature of 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.

“Exiting the TEST Mode”.)
Turn on the main power. While pressing [TUNING +], press
[DBFB], release hand from [DBFB] then press [FUNCTION].
(Keep pressing [TUNING] all the way.)
Pressing these buttons again in the same order exits the TEST
mode.
* The small ATT segment lights in the center top of display during
the TEST mode.
* To exit the TEST mode, disconnect theAC power cord from wall
outlet, or use “How to Enter the TEST Mode - 2”.

Various CD tests
Pressing the two keys at the same time enables the various
adjustment and test as follows in the TEST mode, and “ATT”
segment is flashing.
1) Pressing [TUNING–] and [CD EJECT 6] at the same time :
The present normal tracking balance value (“31” to “36”) is
displayed when the above key operation is performed and
(TRBAL.) is displayed.
The tracking gain is fixed to “3F” (TOG1 to TOG2: all off)
2) Pressing [TUNING–] and [DBFB] at the same time :
(SHUFFLE) is displayed.
• ADJUSTMENT mode
When the above key operation is performed, the machine
enters the ADJUSTMENT mode. The “SHUFFLE” flashes
on display tube.
During the ADJUSTMENT mode:
The CLV gain is not switched to 8 cm. (The CLV gain is
fixed to 12 cm always.)
The machine is ready to enter theAF-ADJUSTMENT mode
as described below.
3) Pressing [TUNING–] and [FUNCTION] at the same time :
(SHUFFLE) and (PROGRAM) are displayed.
• AF-ADJUSTMENT mode
After the machine enters the ADJUSTMENT mode by the
key operation as described in step 2), the machine can enter
the AF-ADJUSTMENT mode by pressing the above key
operation. [TUNING – /FUNCTION]
The “SHUFFLE” and “PROGRAM” flash on display.
During theAF-ADJUSTMENT mode, the tracking and sled
servos are turned off in addition to theADJUSTMENT mode.
The machine stops the GFS error check which is normally
performed by software.
• Sled motor check
When disc is removed by pressing EJECT during the AF-
ADJUSTMENT mode, the sled can be moved to inner
circumferenceoroutercircumference by pressing [TUNING–
] or [TUNING+]. At this time, because the microprocessor
is not sensing the sled position, be careful when moving the
sled not to damage gears and other mechanism.
4) Pressing [TUNING–] and [VOL–] at the same time :
• No CDM mode
[1] is displayed.
When the above key operation is performed, the control on
the slot mechanism which takes in and ejects a CD disc is
stopped.
At this time “1” on the display flashes.
During the no CDM mode,
The TOC data is deleted by the [CD EJECT 6] key.
(When the TEST mode is cleared and a CD disc is inserted,
machine reads the TOC again.)

5) Pressing [TUNING–] and [VOL+] at the same time :
• Aging mode
The machine enters the aging mode by inserting a CD disc
and performing the above button
operation. The display starts counting the aging operation
with COUNT display, and “REPEAT” flashes.
Aging operation
1. Machine takes a disc into the machine.
2. Reads the TOC.
3. Accesses to the last track.
4. Plays back the last 2 seconds.
5. Ejects the disc.
The one complete operation from step 1 to step 5 is one count.
The cycle is repeated. However, steps 2 to 4 are skipped in all
modes other than the CD function.
Steps 1 and 5 are skipped in the no CDM mode.
The aging operation ends when an error occurs.
Aging error display
“Load Error” : Loading operation is not completed in four
seconds.
“Eject Error” : Eject operation is not completed in four
seconds.
“Q TOC Err” : The Q data could not be read during eight
seconds. (During TOC read)
“Q SRCH Err” : The Q data could not be read during eight
seconds. (During track search)
“Q PLAY Err” : The Q data could not be read during eight
seconds. (During PLAY)
“FOK UP Err” : Focus could not be locked in. (During
setup)
“FOK TOC Err” : Focus is un-locked many times. (During
TOC read)
“FOK SRCH Err” : Focus is un-locked many times. (During
track search)
“FOK PLAY Err” : Focus is un-locked several times. (During
play)
“GFS UP Err” : GFS error. (During setup)
“GFS TOC Err” : GFS error. (During TOC read)
“GFS PLAY Err” : GFS error. (During play)
Display selection during aging
The display can be switched by pressing the [TUNING–] and
[FUNCTION] at the same time :
Count display
Elapsed time display
Other errors
Normal display
Example of display
" COUNT 723 " (Machine has repeated for 723 times.)
" 12 : 05 : 35 " (12 hours 5 minutes 35 seconds have elapsed.)
" TW 2 SW 1 "
** Other troubles
“TW*SW*”
TW : Numbers of times that the machine could not read
TOC.
SW : Numbers of times that the machine could not
complete the track search within 16 seconds.
To exit the aging mode and to return the TEST mode, press
[TUNING – ] and [VOL +] at the same time.

CD SECTION
Note:
1. CD Blockisbasicallyconstructedto operate without adjustment.
Therefore, check each item in order given.
2. UseYEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use the oscilloscope with more than 10MΩimpedance.
4. Clean an object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
5. When optical pickupisreplacedduringrepair, perform the focus
bias adjustment.
Focus Bias Adjustment
This adjustment is to be done when the optical block is replaced.
Adjustment procedure:
1. Connect oscilloscope to test point TP (VC) and TP (RF) on BD
board.
2. Turned power switch ON. (Stop state)
3. Insert disc (YEDS-18) and press the ^button.
4. Adjust RV101 so that the oscilloscope waveform is as shown in
the figure below (eye pattern).
A good eye pattern means that the diamond shape (≈) in the
center of the waveform can be clearly distinguished.
•RF signal reference waveform (eye pattern)
When observing the eye pattern, set the oscilloscope for AC
range and raise vertical sensitivity.
S-Curve Check
Procedure:
1. Connect as oscilloscope to test point TP (VC) andTP (FEO) on
BD board.
2. Connect a lead wire between test point TP (FOK) and Ground.
3. Turned Power switch on.
4. Insert disc (YEDS-18) and turned Power switch on again to
actuate the focus search. (actuate the focus search when disc
table is moving in and out.)
5. Check the oscilloscope waveform (S-curve) is symmetrical
betweenA and B.And confirm that peak to peak level is within
2.4 ± 0.7 Vp-p.

•Select a longer sweep time and increase the brightness to
obtain best waveform.
RF Level Check
Procedure:

board.
2. Turned Power switch on.
3. Insert the disc (YEDS-18) and press the ^button.
4. Confirm thatoscilloscopewaveformis clear and checkRFsignal

Focus/Tracking Gain Adjustment
This gain has a margin, so even if it is slightly off. There is no
problem.
Therefore, do not perform, RV102 and RV103 adjustment.
Please note that it should be fixed to mechanical center position
