SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK 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 alsouse 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 OPERATIONCHECKCarry out the S curve check in CD section adjustment and

check that the S curve waveforms is output three times.

PART No.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARKUnleaded solder has the following characteristics.

Unleaded solder melts at a temperature about 40 C higher than

ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 C.

Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

Strong viscosity

Unleaded solder is more viscou-s (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges oc-

cur such as on IC pins, etc.

Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

CD SECTION

Note:1. CD Block is basically designed to operate without adjustment. Therefore,

check each item in order given.

2. Use YEDS-18 (3-702-101-01) unless otherwise indicated.

3. Use an oscilloscope with more than 10Mimpedance.4. Clean the object lens by an applicator with neutral detergent when the

signal level is low than specified value w ith the following checks.

S-CURVE CHECK

Procedure :1. Connect an oscilloscope to TP (FE) and TP (VC).

2. Turn the power on.

3. Load a disc (YEDS-18) and actuate the focus search. (In

consequence of open and close the disc tray, actuate the focus

search)

4. Confirm that the oscilloscope waveform (S-curve) is

symmetrical between A and B. And confirm peak to peak level

within 3 0.5 Vp-p.

Note: Try to measure several times to make sure than the ratioof 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.

RF LEVEL CHECK

Procedure :

1. Connect an oscilloscope to TP (RF) and TP (VC).

2. Turn the power on.

3. Load a disc (YEDS-18) and playback.

4. Confirm that oscilloscope waveform is clear and check if RF

signal level is correct or not.
