SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostaticbreak-down because of the potential difference
generated by thecharged electrostatic load, etc. on clothing and
the human body.During repair, pay attention to electrostatic
break-down and alsouse the procedure in the printed matter which is
included in therepair parts.The flexible board is easily damaged
and should be handled withcare.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
onthe disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emission,
observefrom more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the S curve check in CD section adjustment and
checkthat the S curve waveform is output several times.

2. Turn the adjustment screw and check output peaks. If the
peaksdo not match for L-CH and R-CH, turn the adjustment screwso
that outputs match within 1dB of peak.
3. Mode: Playback
4. After the adjustments, apply suitable locking compound tothe

CD SECTION
Note:1. CD Block is basically designed to operate without
adjustment.
Therefore, check each item in order given.2. Use YEDS-18 disc
(3-702-101-01) unless otherwise indicated.3. Use an oscilloscope
with more than 10MW impedance.4. Clean the object lens by an
applicator with neutral detergent
when the signal level is low than specified value with
thefollowing checks.
S-curve CheckConnection:
Procedure:1. Connect an oscilloscope to test point TPO102 (FE1)
and TP
117(VC) on the CD board.2. Turn the power on.3. Put the disc
(YEDS-18) in and turned power switch on again
and actuate the focus search. (actuate the focus search whendisc
table is moving in and out)
4. Check the oscilloscope waveform (S-curve) is
symmetricalbetween A and B. And confirm peak to peak level within
2.4 1 Vp-p.
S-curve waveform
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.

RFAC Level CheckConnection:
Procedure:1. Connect an oscilloscope to test point TP124 (RFAC)
and TP
117(VC) on the CD board.2. Turn the power on.3. Put the disc
(YEDS-18) in to playback the number five track.4. Confirm that
oscilloscope waveform is clear and check RFAC
signal level is correct or not.Note: A clear RFAC signal
waveform means that the shape can be
clearly distinguished at the center of the waveform.

E-F Balance CheckConnection:
Procedure:1. Connect an oscilloscpe to test point TPO103 (TE1)
and TP117
(VC) on the CD board.2. Turn the power on.3. Select the function
CD.
4. Press three buttons of [ENTER], M , and[SURRUUND MODE]
simultaneously to set the CD servicemode.
5. Put the disc (YEDS-18) in to playback the number five track.
6. Press the . button. The message TRAVERSE is
displayed. (The tracking servo and the sledding servo areturned
OFF)
7. Check the level B of the oscilliscope's waveform and the A(DC
voltage) of the center of the Traverse waveform.Confirm the
following :A/B x 100 = less than 22%
Traverse Waveform
8. Press the . button. The message TRAVERSE isdisplayed. (The
tracking servo and sledding servo are turnedON)Confirm the C (DC
voltage) is almost equal to the A (DCvoltage) is step 5.
9. To exit from this mode, perform as follows.1) Move the
optical pick-up to the most inside track.
2) Press three buttons of x , [CLEAR], and
[DISPLAY]simultaneously. (cold reset)
Notes: Always move the optical pick-up to most inside track
when exiting from this mode. Otherwise, a disc will notbe
unloaded.
Do not run the sled motor excessively, otherwise the gearcan be
chipped.
