Flexible Circuit Board Repairing
• Keep the temperature of the 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 chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
TABLE OF CONTENTS
This Compact Disc player is
classified as a CLASS 1 LASER
product.
The CLASS 1 LASER
PRODUCT label is located 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.
Laser component in this product is capable of emitting
radiation exceeding the limit for Class 1.
DANGER
Invisible laser radiation when open and interlock failed or defeated.
Avoid direct exposure to beam.

D-EJ750/EJ751/EJ753/EJ755/EJ756CK/EJ758CK
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.
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, observe from more
than 30cm away from the objective lens.
Before Replacing the Optical pick-up Block
Please be sure to check thoroughly the parameters as per the “Optical
pick-up Block Checking Procedure” (Part No. : 9-960-027-11) issued
separately before replacing the optical Pick-up block.
Note and specifications required to check are given below.
• FOK output : IC601 yg pin
When checking FOK, remove the lead wire to disc motor.
• RF signal P-to-P value : 0.45 to 0.65Vp-p
SECTION 1
SERVICING NOTES
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser diode
is prohibited unless the upper panel is closed while turning ON the S801
(push switch type).
The following two checking methods for the laser diode are operable.
Method :
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. Push the S801 as shown in Fig. 1 .
3. Check the object lens for confirming normal emission of the laser
diode. If not emitting, there is a trouble in the automatic power
control circuit or the optical pick-up. During normal operation, the
laser diode is turned ON about 2.5 seconds for focus searching.

Focus bias Check
Condition:
• Hold the set in horizontal state.
Connection:
Procedure:
1. Connect the oscilloscope to the test point TP630(RF) on the
MAIN board.
2. Set a disc. (YEDS-18)
3. Press the >B button.
4. Check the oscilloscope waveform is as shown below.
A good eye pattern means that the diamond shape (◊) in the cen-
ter of the waveform can be clearly distinguished.
RF Signal reference Waveform (Eye Pattern)
To watch the eye pattern, set the oscilloscope to AC range and
increase the vertical sensitivity of the oscilloscope for easy
watch-ing.
5. Stop revolving of the disc motor by pressing the x button.
