1. Check the area of your repair for unsoldered or poorly-sol
deredconnections. 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, particularlyt ransis
tors, 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.
SAFETY CHECK-OUT

safety checks before releasing the set to the customer.
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 270°C
