The CRT 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 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:
