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.

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 HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

IC502 OF VIDEO BOARD

IC502 of the VIDEO board consists of the former type and new

type. The following table shows the differences between the two

types.

Only spare parts for the new type IC502 are supplied.

Units using the former IC502 will not function when replaced with

the new type without performing the following procedure.

Consequently, replace IC502 of units using the former type ac-

cording to the following procedure.

Table of Differences

Replacing Procedure

1. Remove IC402.

2. Solder JW421 and JW422, or short-circuit with a lead wire,

etc.

3. Replace IC502 with a new one.
