· Never reuse a disconnected chip component.

· Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

· Keep the temperature of soldering iron around 270°C

during 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

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

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 emission, ob-

serve 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 waveform is output two times.
