1.

Check the area of your repair for unsoldered or poorly-sol-
dered 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.

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

4.

Look for parts which, though functioning, show obvious signs
of deterioration.  Point them out to the customer and recom-
mend their replacement.

5.

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