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 breakdo wn 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.

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 A C leakage. Check leakage as
described below.

LEAKAGE

The A C leakage from any exposed metal par t 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. Follo w 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 v oltmeter . The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd ar e examples of
a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2V AC range are suitable. (See
Fig. A)

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 pick­up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

This unit is able to display the test data (character information) written in the CD on its fluorescent indicator tube.
The CD-TEXT TEST DISC (TGCS-313:4-989-366-01) is used for checking the display.
To check, perform the following procedure.

Checking Method:

1. T urn ON the po wer , set the disc on the disc table with the side labeled as “test disc” as the right side, close the front cover , and c huck the
disc.

2. Press the ” button and play back the disc.

3. The following will be displayed on the fluorescent indicator tube.

Display : 1kHz/0 dB/ L&R

4. Press the = and + buttons to switch the track. The text data of each track will be displayed.
For details of the displayed contents for each track, refer to “T able 1 : CD-TEXT TEST DISC TEXT Data Contents” and “Table 2 : CD­TEXT TEST DISC Recorded Contents and Display”.

Restrictions in CD-TEXT Display

In this unit, some special characters will not be displayed properly. These will be displayed as a space or a character resembling it. For details,

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 10MΩ 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.

S Curve Check

oscilloscope

BD board

TP (FE)
TP (VC)

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.

Note :

A clear RF signal waveform means that the shape “ ◊ ” can
be clearly distinguished at the center of the waveform.

TP (VC)

Procedure :

1. Connect test point TP1 (ADJ) to ground with a lead wire.

2. Connect oscilloscope to test point TP (TE) on BD board.

3. Turned Power switch on.

4. Put disc (YEDS-18) in to play the number five track.

5. Press the “3” button. (The tracking servo and the sledding servo
are turned OFF.)

6. Check the level B of the oscilloscope's waveform and the A
(DC voltage) of the center of the Traverse waveform.
Confirm the following :
A/B × 100 = less than ± 22%

A

within 3 ± 1 Vp-p

B

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.

RF Level Check

Procedure :

1. Connect oscilloscope to test point TP (RF) on BD board.

2. Turned Power switch on.

4. Confirm that oscilloscope waveform is clear and check if RF
signal level is correct or not.
