B. Test
Make sure that the display units stay off.
4. Fault Isolation
_______________
A. If the three display units stay off and if the EIS DMC selector switch (18WT) on the SWITCHING panel 8VU is at NORM:
(1) Do a check for 115VAC at pin AC/2 of the DMC1 (1WT1) (Ref. ASM 31-61/02).
(a) If there is 115VAC:
- replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
