SAFETY CHECK-OUT

After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:

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, par-
ticularly transistors, that were installed during a
previous repair. Point them out to the customer
and recommend their replacement.

SAFETY-RELATED COMPONENT WARNING! !

LINE WITH MARK A ON THE SCHEMATIC DIAGRAMS

LISHED BY SONY.

4. Look for parts which, though functioning, show
obvious signs of deterioration. Point them out
to the customer and recommend their replace-
ment.

5. Check the B+ voltage to see it is at the values
specified.
