This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the
projector, it will automatically turn off by operating one of the following protection circuits.
A fuse(F601) is located inside of the projector. When
the POWER indicator is not lightning, the fuse may be
opened. Check the fuse as following steps.
The fuse should be used with the following type;
●
Fuse

How to replace the fuse
1.
Remove the cabinet top and main board following to
"Mechanical Disassemblies".
2.
Remove the fuse from fuse holder on the Filter
Board.
To install the fuse, take reversed step in the above.
There is the thermal switch (SW902) inside of the pro-
jector to prevent the internal temperature rising abnor-
mally. When the internal temperature reaches near
90°C, the thermal switch cuts off the drive signal to the
lamp circuit automatically. The thermal switch is not
reset to normal automatically, even if the internal tem-
perature becomes normal. Reset the thermal switch fol-
lowing procedure.
Check the resistance between terminals of thermal
switch by using a tester. If it has high impedance, ther-
mal switch may be open.
How to reset the thermal switch
1.
Remove the cabinet top ass'y following to
"Mechanical Disassemblies".
2.
