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, particularly transis-
tors, that were installed during a previous repair. Point them out to
the customer and recommend their replacement.
