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.
ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFÉS PAR UNE MARQUE 0 SUR LES
DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT
CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE
REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY
DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU
DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.
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.
4.
Look for parts which, through 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.
6.
FLEXIBLE Circuit Board Repairing
• Keep the temperature of the soldering iron around 
350
˚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.
Unleaded solder
This unit uses 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
Be careful to the following points to solder or unsolder.
Set the soldering iron tip temperature to 350˚C approximately.
If cannot control temperature, solder/unsolder at high
temperature for a short time.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
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.
Be sure to control soldering iron tips used for unleaded solder
and those for leaded solder so they are managed separately.
Mixing unleaded solder and leaded solder will cause detachment
phenomenon.
SAFETY  CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer.
CAUTION
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type.
Dispose of used batteries according to the instructions.
