Fuse(F601)
A fuse is located inside of the projector. When the ON(G)/
STANDBY(R) indicator is not lighting, the fuse may be
opened. Check the fuse as following steps.
The fuse should be used with the type listed right;
How to replace the fuse
1. The fuse is placed on the filter board behind the main
board. Remove the cabinet top, AV panel and main
board.
2. Take the fuse off, and replace the old one with the
specified type.
Lamp cover switch(SW901)
The lamp cover switch (SW901) cuts off the drive signal
to the lamp circuit when the lamp cover is removed or
not closed completely. After opening the lamp cover for
replacing the lamp ass’y, place the lamp cover correctly
otherwise the projector can not turn on.
Thermal fuse(SW902)
There is the thermal fuse (SW902) inside of the projec-
tor to detect the internal temperature rising abnormally.
When the internal temperature reaches near 94˚C, the
thermal fuse opens to cut off the power to the power
circuit.
If the thermal fuse opens, the projector cannot turn on.
Thermal fuse replacement is required.
