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
lead-free 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.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINE
WITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND IN THE
PA RTS LIST ARE CRITICAL TO SAFE OPERATION.
REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE
PA RT NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN
SUPPLEMENTS PUBLISHED BY SONY.

SECTION 1
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 : 0.45 to 0.75Vp-p
D-FJ210/FJ215
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.

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.

VOLT/DIV : 100 mV (With the 10 : 1 probe in use)
TIME/DIV : 500ns
RF level
0.45 to 0.75 Vp-
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.
