DANGER

Invisible laser radiation when open and interlock failed or defeated.
Avoid direct exposure to beam.

CAUTION

Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation
exposure.

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.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free 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 MARK

Unleaded 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 viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

• Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

SERVICING NOTES

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.

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 : 0.4 to 0.8Vp-p

D-EJ250

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
S809(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 S809 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.

Procedure:

1. Connect the oscilloscope to the test point TP601(RF) on the
MAIN board.

2. Set a disc. (YEDS-18)

3. Press the u button.

4. Check the oscilloscope waveform is as shown below.
A good eye pattern means that the diamond shape (

) in the

center of the waveform can be clearly distinguished.

TIME/DIV : 500ns

RF level

0.4 to 0.8 Vp-p

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.

• A : B+ Line.

• Power voltage is dc 4.5 V and fed with regulated dc power supply
from battery terminal.

•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.

• Circled numbers refer to waveforms.

• Signal path.
