NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer
electrostatic breakdown because of the potential difference
generated by the charged electrostatic load, etc. on clothing and
the human body.
During repair, pay attention to electrostatic breakdown 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.
SAFETY CHECK-OUT
(US model only)
After correcting the original service problem, perform
the following safety checks before releasing the set to the
customer: |
Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
leakage. Check leakage as described below.
LEAKAGE
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any exposed
metal part having a return to chassis, must not exceed 0.5
mA (500 microampers). Leakage current can be measured
by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229
or RCA WT-540A. Follow the manufacturers’
instructions to use these instruments.
2. <A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for this
job.
3. Measuring the voltage drop across a resistor by means
of a VOM or battery-operated AC voltmeter. The
“limit” indication is 0.75 V, so analog meters must
have an accurate low-voltage scale. The Simpson 250
and Sanwa SH-63Trd are examples of a passive VOM
that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable.

Insert a tapering driver into the aperture of the unit bottom, and turn in the
direction of arrow (to OUT direction).
* To close the disc tray, turn the driver in the reverse direction

SECTION 3
ELECTRICAL BLOCK CHECKING
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 1OMQ impedance.
4. Clean the object lens using an applicator with neutral
detergent when the signal level is low than specified value
with the following checks.

oscilloscope
BD board
Procedure :
1. Connect oscilloscope to test point TP (FE) on BD board.
2. Connect between test point TP (FEI) and TP (VC) by lead
wire.
3. Turn Power switch on.
4. Put disc (YEDS-18) in and turn Power switch on again and
actuate the focus search. (actuate the focus search when disc
table is moving in and out.)
5. Check if the oscilloscope waveform (S-curve) is
symmetrical between A and B. And confirm peak to peak
level within 3+1 Vp-p. ,
S-curve waveform symmetry
within 3 + 1 Vp-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.
«Set sweep time as long as possible and set the
brightness to obtain best waveform.

Procedure :
1. Connect oscilloscope to test point TP (RFO) on BD board.
2. Turn Power switch on.
3. Put disc (YEDS-18) in and playback.
4. Confirm that oscilloscope waveform is clear and check if RF
signal level is correct or not.
Note :
A clear RF signal waveform means that the shape “(” can
be clearly distinguished at the center of the waveform.
