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 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.

Flexible Circuit Board Repairing
