Unsolder and remove component.
Clean pads.

coating residue from the area.  Use care to avoid damage
to traces or pads.
Clean the area around the top and bottom component lead

pads with cotton swabs (item 16, App. D) and the cleaning
solution (item 14, App. D).
Insert the new component in the CCA and trim leads to the

proper length.
Solder the new component in place.
(9)
(10) After soldering all leads, clean the connections with the
stiff brush (item 3, App. D) and cleaning solution (item
14, App. D).
(11) Retest the CCA to verify successful repair and proper
operation.
(12) Determine the type of conformal coating used on the

strips away from the coating, the coating is humiseal 1B31
(item 9, App. D); if it does not strip away, the coating
is humiseal 1A33 (item 9, App. D).

(13) Patch the conformal coating with the appropriate type of
humiseal in the test and repair areas.

proceed as follows:
(1)
Remove the four screws (17) and flat washers (18) that
secure the heat sink and voltage regulator (16) to the
chassis, then remove the heat sink and voltage regulator.
(2)
Disconnect connector A1P1 (67) from voltage regulator
(16) by unscrewing screws in screw lock assemblies (68).
Attach connector A1P1 (67) to voltage regulator A1 (16).
(3)
(4)
Aline voltage regulator A1 (16) with the mounting holes
and secure with the four screws (17) and flat washers
(18) .
