SERVICING NOTES
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the lid (CD), use
Chuck Plate Jig.
• Code number of Chuck Plate Jig: X-4918-255-1
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown 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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Turn OPERATE switch on with to disc inserted and press
FUNCTION button to CD position.
2. Open the lid (CD).
3. Turn on S801 as following figure.
4. Press the ( (CD) button.
5. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Po wer Control circuit or
Optical Pick-up is broken.
Objective lens moves up and do wn three times for focus search.
S801
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 pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
This Compact Disc player is classified as a
CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT table is
location on the rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.

Notes on Adjustment
1. Perform adjustment in test mode.
After adjustments, be sure to release test mode.
2. Perform adjustments in the order given.
3. Use the disc (YEDS-18. Part No. 3-702-101-01) only when so
indicated.
How to Put the Set into Test Mode
1. Disconnect an AC plug cord. (Power is not applied to the set.)
2. Solder across the TEST1 terminal.
3. Close the lid (CD).
4. Connect an AC plug cord.

3. Put the set into test mode.
4. Press the + and = buttons to move the optical pick-up to
the center.
5. Press the ( button.
From focus searching, focus is turned ON while entering
CLV drawing-in mode. Tracking and sled are turned OFF.
6. Adjust R V703 so tha t the oscilloscope traverse wav eform is symmetrical, as shown in the figure below.
Note: Take long sweep time
VOLT/DIV: 0.2 V (with the 10:1 probe in use.)

for easy monitoring.
How to Release the Test Mode
1. Be sure to disconnect the AC plug cord and remove the solder
bridge at the TEST1 terminal connected before in setting.
2. The set thus becomes available for normal operation
Before Beginning Adjustment
Put the set into test mode and perform the following checks.
Repair if there are any problems.
• Sled Motor Check
Press the +, = buttons and confirm that the optical pick-up
moves smoothly from the innermost to outermost circumference
and back smoothly and with no catching or abnormal noises.
+ : Optical pick-up moves to the outer circumference
= : Optical pick-up moves to the inner circumference
• Focus Search Check
1. Press the ( button. (Focus search operation is performed continuously.)
2. Look at the optical pick-up objective lens and confirm that it
moves up and down smoothly, when no catching or abnormal
noises.
3. Press the p button.
Confirm that focus search operation stops. If it does not , press
the p button again longer.

6. Press the ( button.
[Both tracking and sled are turned ON.]

REFERENCE
Focus/Tracking Gain Adjustment
A frequency response analyzer is necessary in order to perform this
adjustment exactly .
However , this gain has a mar gin, so e ven if it is slightly off, there is
no problem. Therefore, do not perform this adjustment.
Focus/tracking gain determines the pick-up follow-up (vertical and
horizontal) relative to mechanical noise and mechanical shock when
the 2-axis device operate.
However, as these reciprocate, the adjustment is at the point where
both are satisfied.
• When gain is raised, the noise when the 2-axis device operates
increases.
• When gain is lowered, mechanical shock and skipping occurs
more easily.
• When gain adjustment is off, the symptoms below appear.
