SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety checks before releasing the set to the customer:
Check the area of your repair for unsoldered or poorly-
soldered connections, Check the entire board surface for
solder splashes and bridges.
Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
Look for unauthorized replacement parts, particularly
transistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
Check the B+ voltage to see it is at the values specified.
‘SAFETY-RELATED COMPONENT WARNINGI!
COMPONENTS IDENTIFIED BY MARK A\ OR DOTTED LINE WITH
MARK A\ ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS
LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE
‘COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR
