 - replace the CONTROLLER-LIGHTING (16LF) (Ref. AMM TASK 33-13-51-000-001) and (Ref. AMM TASK 33-13-51-400-001). (Ref. Fig. 202/TASK 33-13-00-991-001)
 1 If the fault continues:
_
 - do a check and repair the wiring related to the defective lighting circuit (Ref. ASM 33-13/01).
 (b) If the fuse is not correct:
 - replace the defective fuse.
 (3) If all the integrally lighted panels do not operate correctly:
 - do a check of the circuit breaker (4LF) status.
 (a) If the circuit breaker is closed:
 - do a check for 115VAC at pin A/A of the lighting controller (16LF) (Ref. ASM 33-13/01).
 1 If there is 115VAC:
_
 - replace the CONTROLLER-LIGHTING (16LF) (Ref. AMM TASK 33-13-51-000-001) and (Ref. AMM TASK 33-13-51-400-001).
 a If the fault continues:
_
 - replace the POT-INTEG LT/MAIN PNL & PED (17LF) (Ref. IPC 331308).
 b If the fault continues:
_
 - do a check and repair the wiring between the lighting controller (16LF) and the INTEG LT/MAIN PNL & PED potentiometer (17LF).
 2 If there is no 115VAC:
_
 - do a check for a ground signal at pins A/C, B of the lighting controller (16LF) (Ref. ASM 33-13/01).
 a If there is no ground signal:
_
 - repair the defective wiring between the lighting controller (16LF) pin A/C or A/B and the ground terminal (Ref. ASM 33-13/01).

 b_ If there is a ground signal:
 - replace the C/B-LIGHTING/INST LT/MAIN INST/PNL AND/PED
 (4LF)
 . if the fault continues:
 * do a check and repair the wiring between the lighting
 controller (16LF) pin A/A and the C/B (4LF) (Ref. ASM 33-
13/01).

 - close the circuit breaker.
 1 If the circuit breaker trips:
_
 - replace the CONTROLLER-LIGHTING (16LF) (Ref. AMM TASK 33-13-51-000-001) and (Ref. AMM TASK 33-13-51-400-001).
 a If the fault continues:
_
 - do a check for a short to ground at the wiring between the lighting controller (16LF) pin A/A and the circuit breaker (4LF) (Ref. ASM 33-13/01) . if there is a short to ground:
 * repair the related wiring. . if there is no short to ground:

 * replace the C/B-LIGHTING/INST LT/MAIN INST/PNL AND/PED (4LF).

 B. Do the test given in Para. 3.

__________________
 A. Test Do the operational test of the instrument and panel integral-lighting (Ref. AMM TASK 33-13-00-710-001). (Ref. Fig. 203/TASK 33-13-00-991-005)
 NOTE : Do this test for the overhead-panel integral lighting only.

_______________
 A. If during the operational test when you turn the INT LT/OVHD INTEG LT potentiometer (7LF) from OFF to BRT.
 (1) One light of the related integrally lighted panel is inoperative:
 - remove the defective lamp or LED of the PLATE-INT LIGHTED IDENT (Ref. IPC 331308).

 - make sure that there is a voltage at the lamp socket.

 (a) If there is a voltage:
