WARNING!!
WHEN  SERVICING,  DO  NOT  APPROACH  THE  LASER
EXIT  WITH  THE  EYE  TOO  CLOSELY.  IN  CASE  IT  IS
NECESSARY  TO  CONFIRM  LASER  BEAM  EMISSION,
BE  SURE  TO  OBSERVE  FROM  A  DISTANCE  OF
MORE   THAN   25  cm  FROM  THE  SURFACE  OF  THE
OBJECTIVE  LENS  ON  THE  OPTICAL  PICK-UP  BLOCK.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
SAFETY-RELATED  COMPONENT  WARNING!!
COMPONENTS  IDENTIFIED  BY  MARK  
0
  OR  DOTTED
LINE  WITH  MARK  
0
  ON  THE  SCHEMATIC  DIAGRAMS
AND  IN  THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE
OPERATION.  REPLACE  THESE  COMPONENTS  WITH
SONY  PARTS  WHOSE  PART  NUMBERS  APPEAR  AS
SHOWN  IN  THIS  MANUAL  OR  IN  SUPPLEMENTS
PUBLISHED  BY  SONY.
CAUTION:
The use of optical instrument with this product will increase eye
hazard.
1. Check the area of your repair for unsoldered or poorly-soldered
connections.  Check the entire board surface for solder splashes
and bridges.
2. Check the interboard wiring to ensure that no wires are “pinched”
or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly transistors,
that were installed during a previous repair.  Point them out to the
customer and recommend their replacement.
SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
This appliance is classified as 
a CLASS 1 LASER product. 
The CLASS 1 LASER 
PRODUCT MARKING is 
located on the rear exterior.
4. Look for parts which, though functioning, show obvious signs of
deterioration.  Point them out to the customer and recommend
their replacement.
5. Check the B+ voltage to see it is at the values specified.
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.

Precautions
1 Handling the Optical Pick-up
The laser diode in the optical pick up may suffer electrostatic
breakdown because of potential static electricity from
clothing and your body.
The following method is recommended.
(1) Place a conductive sheet on the work bench (The black
sheet used for wrapping repair parts.)
(2) Place the set on the conductive sheet so that the chassis is
grounded to the sheet.
(3) Place your hands on the conductive sheet (This gives
them the same ground as the sheet.)
(4) Remove the optical pick up block
(5) Perform work on top of the conductive sheet. Be careful
not to let your clothes or any other static sources to touch
the unit.
◆ Be sure to put on a wrist strap grounded to the sheet.
◆ Be sure to lay a conductive sheet made of copper etc.
Which is grounded to the table.
(6) Short the short terminal on the PCB, which is in-side the
Pick-Up ASS’Y, before replacing the Pick-Up. (The short
terminal is shorted when the Pick-Up Ass’y is being lifted
or moved.)
(7) After replacing the Pick-up, open the short terminal on
the PCB.
