This section describes the replacement of the CRT/MDI controller PCB
fuse of the Power Mate–D. The table below lists the drawing number of
the CRT/MDI control PCB. The CRT/MDI control PCB is mounted on
the back of the CRT/MDI unit or separate MDI unit.

The CRT/MDI control PCB contains a +24 V power input fuse, FU1. If
nothing appears on the screen when +24 V power is supplied to the
CRT/MDI control PCB, fuse FU1 may have blown. In such a case,
remove the fuse from its socket, then check its continuity using a
multimeter (or visually check whether it has blown). If the fuse has
blown, investigate the cause, take appropriate action, then replace the
fuse. The capacity, part number, and location of the fuse are as follows:
