SECTION 1

SERVICING NOTES

CHUCK PLATE JIG ON REPAIRING

On repairing CD section, playing a disc without the CD lid, use

Chuck Plate Jig.

• Code number of Chuck Plate Jig: X-4918-255-1

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.

LASER DIODE AND FOCUS SEARCH OPERATION

CHECK

1. Turn POWER switch on with no disc inserted and make Func-

tion switch to CD position.

2. Open the lid for CD.

3. Turn on S701 as following figure.

4. Press the ubutton.

5. Confirm the laser diode emission while observing the object-

ing lens. When there is no emission, Auto Power Control cir-

cuit or Optical Pick-up is broken.

Objective lens moves up and down three times for the focus

search.

Tape Speed Adjustment

Setting:

Function: TAPE

Procedure:

1. Playback WS-48A (tape center) in the FWD state.

2. Adjust the volume in CAPSTAN/REEL motor (M301) so that

the frequency counter reading becomes 3,000 Hz.

Specified Value: 2,985 to 3,015 Hz

3. Confirm that the frequency at the beginning and that at the

end of tape winding are between 2,955 to 3,045 Hz.

CD SECTION

CD section adjustments are done automatically in this set.

In case of operation check, confirm that focus bias.

Focus Bias Check

1. Connect the oscilloscope to TP (RFO) and TP (GND) on the

CD board.

2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)

3. Press the [ ] (CD) button.

4. Confirm that the oscilloscope waveform is as shown in the

figure below. (eye pattern)

A good eye pattern means that the diamond shape (◊) in the

center of the waveform can be clearly distinguished.

• RF signal reference waveform (eye pattern)

VOLT/DIV: 0.2 V (with the 10: 1 probe in use)

TIME/DIV: 500 ns

1.2

±

0.1 Vp-p

When observing the eye pattern, set the oscilloscope

for AC range and raise vertical sensitivity.
