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.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous ra-

diation exposure.

SECTION 1

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

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.

LASER DIODE AND FOCUS SEARCH OPERATION

CHECK

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

check that the S curve waveforms is output three times.
