CD SECTION
Note:
1. CD Block is basically constructed to operate without adjustment.
Therefore, check each item in order given.
2. UseYEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10M impedance.
4. Clean the objectlensby an applicatorwith neutral detergent when
the signal level is low than specified value with the following
checks.
S Curve Check
oscilloscope
BD board
TP (FEO)
TP (VC)
Procedure :
1. Connect oscilloscope to test point TP (FEO).
2. Connect between test point TP (FOK) and Ground by lead wire.
3. Turn Power switch on.
4. Put disc (YEDS-18) in and turned Power switch on again and
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 be-
tweenAand B.And confirm peakto peak level within3 ± 1Vp-p.

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.
• Takesweep time aslong as possibleand light up the bright-
ness to obtain best waveform.
Procedure :
1. Connect oscilloscope to test point TP (RF) on BD board.
2. Turned Power switch on.
3. Put disc (YEDS-18) in and playback.
4. Confirm that oscilloscope waveform is clear and check RF sig-
nal level is correct or not.
Note: Clear RF signal waveform means that the shape “◊” can be
clearly distinguished at the center of the waveform.

2. Turned Power switch on.
3. Put disc (YEDS-18) in to play the number five track.
4. Press the “P(Pause)” button.
5. Check the level B of the oscilloscope's waveform and theA (DC
voltage) of the center of the Traverse waveform.
Confirm the following:

NOTE :
rDue to standardization, replacements in the
parts list may be different from the parts speci-
fied in the diagrams or the components used on
the set.
r-XX, -X mean standardized parts, so they may
have some difference from the original one.
rRESISTORS
All resistors are in ohms
METAL : Metal-film resistor
METAL OXIDE :Metal oxide-film resistor
F : nonflammable
rItems marked “ * ”are not stocked since they
are seldom required for routine service. Some
delayshould be anticipated when orderingthese
items.
rSEMICONDUCTORS
In each case, u : µ, for example :
uA.... : µA.... , uPA.... : µPA....
uPB.... : µPB.... , uPC.... : µPC....
uPD.... : µPD....
rCAPACITORS
uF : µF
rCOILS
uH : µH
The components identified by mark !
or dotted line with mark !are critical
for safety.
