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
damaged by heat.

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 breakdo wn 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 objectiv e lens in the optical pick-up
block. Therefore, when checking the laser diode emission, observe
from more than 30 cm away from the objective lens.
Before Replacing the Optical Pick-Up Block
Please be sure to check throughly the parameters as par the “Optical
Pick-Up Block Checking Procedures” (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 : IC501 @∞ pin
When checking FOK, remove the lead wire to disc motor.
• S curve P-to-P value : 2.0Vp-p IC501 $• pin
When checking S curve P-to-P value, remove the lead wire to
disc motor.
• RF signal P-to-P value : 0.6 - 1.3Vp-p
• Traverse signal P-to-P value : 0.8 - 2.8Vp-p
• The repairing grating holder is impossible.
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper lid is closed while turning ON
the S808 (push switch type).
The following checking method for the laser diode are operable.
Emission of the laser diode is visually checked
1. Open the upper lid.
2. Push the S808 as shown in Fig. 1.
3. Chec k the objective 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.
S808
Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the objective lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc.
Therefore, be sure to keep your eyes more than 30 cm apart from
the objective lens when you check the emission of laser diode.

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 between IC501 pin #¡ (TP552 (RF))
and GND on Main board.
2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01)
3. Press the ^ 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 : 200 mV (10 : 1 probe in use)
TIME/DIV : 500 nS
RF level :
0.8-1.8 Vp-p
π
When observing the eye pattern, set the oscilloscope for AC range
and raise vertical sensitivity.

• U : B+ Line.
• Power voltage is dc 3 V and fed with regulated dc power
supply from battery terminal.
• Voltages and wav eforms are dc with respect to ground in
playback mode.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Signal path.
