Fuses
There are no user-replaceable parts on any of the circuit boards. If you suspect
that an open fuse exists, there is no easy way of determining the cause of the
open fuse. Most of the fuses are surface mounted and attempting to change the
fuses with improper tools will result in damaging the circuit boards beyond
repair. You should return the circuit board to you local Tektronix service center
for corrective action.
