arm during the rewinding operation. Generally,
a projector has either spring belts or fabric belts.
The type is determined by the make and model.
The belts must be inspected for cleanliness
and kinks. The belts should be cleaned with a
naphtha-base solvent. Any kinks in the belts
must be taken out. Consult the operation
instruction manual for the specific make and
model of the projector for methods of removing
and installing the belts and for regulating the
tension applied to the belts.
FUSE REPLACEMENT.Make certain that
the projector power cable had been disconnected
from the power source before you attempt to
remove a projector fuse. Some projectors have
two fuses, the power fuse, and the amplifier
fuse. To remove a fuse, follow published
instructions for the specific projector. Usually, a
fuse may be removed by unscrewing the fuse
post with a screwdriver or by turning the fuse
cap slightly in a counterclockwise direction with
a screwdriver and then pulling the fuse out.
