to install the fuse, take reversed step in the above.
There are the thermal switches (SW903 and SW904) inside of the projec-
tor to detect the internal temperature rising abnormally. When the internal
temperature reaches near 80˚C, the thermal switch opens to cut off the error
detection signal supplied to the system control part and then the projector will
set in the power failure mode.
The thermal switch will automatically return to normal condition when the
internal temperature becomes normal.
