SAFETY CHECK-OUT

After correcting the original service problem, perform the follow-

ing safety check 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 TEST

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 microamperes.).

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” indica-

tion is 0.75 V, so analog meters must have an accurate low-

voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex-

amples of a passive VOM that is suitable. Nearly all battery

operated digital multimeters that have a 2 V AC range are suit-

able. (See Fig. A)

SECTION 1

SERVICING NOTES

The laser diode in the optical pick-up block may suffer electro-

static 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 emis-

sion, observe from more than 30 cm away from the objective lens.

HOW TO OPEN THE DISC TABLE WHEN POWER

SWITCH TURNS OFF

Insert a tapering driver into the aperture of the unit bottom, and

turn it in the direction of the arrow (to OUT direction).

table

tapering driver

*To close the disc table, turn the tapering

driver in the reverse direction (to IN direction).

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C dur-

ing 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.

NOTES ON CLEANING OF OPTICAL PICK-UP LENS

Do not clean up the optical pick-up lens.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous ra-

diation exposure.

Carry out the “S curve check” in “CD section adjustment” and

check that the S curve waveforms is output three times.

This set has the Aging mode for operation check of the mechanism deck.

• If a failure occurred

The aging operation stops and a faulty status is displayed on the fluorescent indicator tube.

• If no failure occurs

The aging operation continues repeatedly.

Note: Do not use the test disc when performing aging.

Aging will not be performed properly if discs with tracks shorter than 4 seconds are used.

Procedure:

1. Press the [POWER] button and turn ON the power.

2. Set discs on all trays.

(More than two discs if five are not available)

3. All mode:

Press the

[CHECK], [CONTINUE] and x buttons at the same time.

Disc table mode:

Press the [CHECK], [CONTINUE] and [DISC SKIP] buttons at the same time.

Loading mode:

Press the [CHECK], [CONTINUE] and [EX-CHANGE] buttons at the same time.

4. Aging starts, and the fluorescent indicator tube will display as follows.

(a) A : All mode

AD : Disc table mode

AL : Loading mode

NG : failure occurred

(b) Code No.

(c) Aging count (000001 to 999999)

5. To exit the mode, press the [POWER] button to turn OFF the power.

MECHANISM DECK CHECK MODE

For the mechanism desk check mode, two modes of the disc table mode and the loading mode are available.

In the mechanism deck check mode, the disc table rotating time and the loading time in each section are measured and displayed.

Disc Table Mode

Procedure:

1. Press the [POWER] button while pressing three buttons of H , [ OPEN/CLOSE], and [REPEAT] simultaneously.

2. Start the table mode, and turn to right then turn to left, and display rotating time as follows.

3. To release from this mode, press the

[POWER] button to turn OFF the power.

Loading Mode

Procedure:

1. Press the

[POWER] button while pressing three buttons of H , [ OPEN/CLOSE], and [TIME/TEXT] simultaneously.

2. Start the loading mode and display as follows.

Note:

1. CD Block is basically designed to operate without adjustment. There-

fore, check each item in order given.

2. Use PATD-012 disc (4-225-203-01) unless otherwise indicated.

3. Use an oscilloscope with more than 10MΩ impedance.

4. Clean the object lens by an applicator with neutral detergent when the

signal level is low than specified value with the following checks.

S Curve Check

Connection:

Procedure:

1. Set the test disc (PATD-012). Disc chucking operation is

complete, then press the [POWER] button to turn the power

off.

2. Connect an oscilloscope to test point TP (FE1) and TP (VC)

on the BD board.

3. Connect between test point TP (ADJ) on the MAIN board and

GND by lead wire.

4. Press the [POWER] button to turn the power on and enter the

ADJ mode.

Then playback the number two track automatically, press the

x button to stop the playback.

5. Press the [CHECK] button actuate the focus search. (actuate

the focus search when disc table is moving in and out)

6. Check the oscilloscope waveform (S-curve) is symmetrical

between A and B. And confirm peak to peak level within 2 ± 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.

5. Confirm that oscilloscope waveform is clear and check the level

of between RFDC top and VC is correct or not.

Note: A clear RFDC signal waveform means that the shape “◊” can be

clearly distinguished at the center of the waveform.
