■ TO SERVICE PERSONNEL

1. Critical Components Information.

Components having special characteristics are marked and must be replaced with parts having specifications equal to those originally installed.

2. Leakage Current Measurement (For 120V Models Only).

When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits.

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

● Leakage current must not exceed 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

To Prevent Damage to the Laser Diode

Static electricity destroys the Laser Diode. Always take countermeasures to prevent static electricity damage when prerforming repairs around the Laser Pick-Up.

1. Do not touch the area around the Laser Pick-Up or the Actuator.

2. Do not check the Laser Diode with a tester or other device (the Laser Diode can be broken quite easily).

3. Short-circuit the Laser Pick-Up Solder the Land in the center of the flexible cable of the Laser Pick-Up. This will short-circuit the Laser Diode and help prevent damage from static electricity. If the flexible cable has no Land, short-circuit TP20 and TP21 (See Fig. 6). This will provide the same protection as when the Land is used for shorting the flexible cable.

Caution:

Do not forget to remove the soldered Laser Diode short-circuit after finishing repair, and leave the circuit open.

■ MAIN P.C.B. OPERATION CHECK

With PLAY operated in the test mode, even when the disc is played, the audio and video signals of the disc are not output from the audio/video output terminal. In order to check the Main P.C.B. while confirming the sound /image of a disc, use the following procedure.

a. Remove the top cover. b. Connect the power plug and then turn on the power

switch. c. Play a disc. d. Press the PLAYXCHANGE button.(This sets the tray

ejected without interrupting playing.)

Tilt Adjustment of Disc Motor

After replacing parts in the Traverse Unit, it is necessary to adjust the Tilt Adjustment of Disc Motor from bottom side. Please follow the following procedures for adjusting.

When the following parts have been replaced, disc motor adjustment will be required.

1. The disc motor.

2. The laser pick-up.

3. The traverse motor unit.

4. The parts around the laser pick-up (rail, etc.).

Preparation before adjustment (Installation of the traverse unit)

Be sure to make both your body and the work table grounded.

a. Connect the power plug and then turn on the power

switch.

b. When the clamp has moved up, turn off the power

switch and disconnect the power plug.

c. Remove the Tray referring to "Removal of Tray" on

page 7. d. Remove the Clamp Assembly. e. Remove the Traverse Unit.

(Take the protection measure against static electricity

for the Laser Diode except when replacing the Laser

Pick-up.) f. Place the Adjusting Box on the CM-200 unit (to

support the traverse unit). (Fig. 15) g. After replacing the parts, place the Traverse Unit on

the Adjusting Box. (Fig. 15)

Caution:

1. Optical adjustment inside the laser pick-up is not possible.

2. Prior to adjusting, take countermeasures to prevent damage from static electricity.
