SAFETY CHECK-OUT
1. Check the area of your repair for unsoldered or poorly-sol-
dered 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 transis-
tors, that were installed during a previous repair.  Point them
out to the customer and recommend their replacement.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
4. Look for parts which, though functioning, show obvious signs
of deterioration.  Point them out to the customer and recom-
mend their replacement.
5. Check the B+ voltage to see it is at the values specified.
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 ra-
diation exposure.
SAFETY-RELATED  COMPONENT  WARNING!!

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  PUB-
LISHED  BY  SONY.
CAUTION:
The use of optical instrument with this product will increase eye
hazard.
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.
 appliance is classified as a 
CLASS 1 LASER product. The 
CLASS 1 LASER PRODUCT 
MARKING is located on the rear 
exterior.
