- the VMU (100MH) connector A/4 and the TU (50MH) connector B/2 (C/2).
C. If the indications on the SCU and on the VTR(s) are normal, but two of the VIDEO MONITOR UNITS (VMU) 100MH (that are served by the same TAPPING UNIT (TU) 50MH) do not extend and/or retract:
(1) Replace the TAPPING UNIT (50MH) that serves the VMUs (100MH) which do not extend and/or retract, (Ref. AMM TASK 23-36-44-000-001) and (Ref. AMM TASK 23-36-44-400-001).
(2) If the fault continues:
(a) Do a check and repair as necessary the wiring between the VMUs (100MH) that do not extend and/or retract and the TU (50MH) that serves them, (Ref. ASM 23-36/02) and (Ref. ASM 23-36/02):
- the VMU (100MH) connector A/6 and the TU (50MH) connector B/7 (C/7)
- the VMU (100MH) connector A/7 and the TU (50MH) connector B/8 (C/8)
- the VMU (100MH) connector A/8 and the TU (50MH) connector B/6 (C/6)
- the VMU (100MH) connector A/2 and the TU (50MH) connector B/10 (C/10)
- the VMU (100MH) connector A/3 and the TU (50MH) connector B/9 (C/9)
- the VMU (100MH) connector A/5 and the TU (50MH) connector B/4 (C/4)
- the VMU (100MH) connector A/1 and the TU (50MH) connector B/1 (C/1)
- the VMU (100MH) connector A/4 and the TU (50MH) connector B/2 (C/2).

D. If the indications on the SCU and on the VTR(s) are normal, but more than two VIDEO DISPLAY UNITS (100MH) (that are mounted on the same side of the cabin) do not extend and/or retract:
(1) Replace the TERMINATOR (51MH1) if the related VMUs (100MH) are mounted on the LH side of the cabin (Ref. ASM 23-36/02).
(2) Replace the TERMINATOR (51MH2) if the related VMUs (100MH) are mounted on the RH side of the cabin (Ref. ASM 23-36/02).
(3) If the fault continues:
(a) Replace the TAPPING UNIT (50MH) that controls the VMU (100MH) which does not extend and/or retract and is mounted most forward in the cabin, (Ref. AMM TASK 23-36-44-000-001) and (Ref. AMM TASK 23-36-44-400-001).
(4) If the fault continues and there is another TU (50MH) mounted more forward in the cabin than the one you replaced:
(a) Do a check and repair as necessary the wiring between the replaced TU (50MH) and the TU (50MH) more forward in the cabin, (Ref. ASM 23-36/02) and (Ref. ASM 23-36/02):
- the replaced TU (50MH) connector A/8 and the more forward TU (50MH) connector D/8
- the replaced TU (50MH) connector A/15 and the more forward TU (50MH) connector D/15
- the replaced TU (50MH) connector A/5 and the more forward TU (50MH) connector D/5
- the replaced TU (50MH) connector A/12 and the more forward TU (50MH) connector D/12
- the replaced TU (50MH) connector A/13 and the more forward TU (50MH) connector D/13
- the replaced TU (50MH) connector A/1 and the more forward TU (50MH) connector D/1
- the replaced TU (50MH) connector A/9 and the more forward TU (50MH) connector D/9
- the replaced TU (50MH) connector A/2 and the more forward TU (50MH) connector D/2
- the replaced TU (50MH) connector A/10 and the more forward TU (50MH) connector D/10
- the replaced TU (50MH) connector A/3 and the more forward TU (50MH) connector D/3
- the replaced TU (50MH) connector A/11 and the more forward TU (50MH) connector D/11
- the replaced TU (50MH) connector A/4 and the more forward TU (50MH) connector D/4.
(5) If the fault continues, replace the VIDEO CONTROL UNIT (11MH) (VCU). (Ref. AMM TASK 23-36-34-000-001) and (Ref. AMM TASK 23-36-34-400-001).

301-399, May 01/05 CES (6) If the fault continues:
(a) Do a check and repair as necessary the wiring between the VIDEO MOUNTING (VM) of the VMU (100MH) and the first TU (50MH) on each of the two sides of the cabin, (Ref. ASM 23-36/01) and (Ref. ASM 23-36/02):
