Circuit Protections
Lamp cover switch
The lamp cover switch 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 assy, place the lamp cover correctly otherwise the 
projector cannot turn on. 
Thermal switch 
There is a thermal switch inside of the projector to detect 
the internal temperature rising abnormally. When the 
internal temperature around lamp reaches near 120°C , 
the thermal switch will open to cut off the power supply to 
the lamp power circuit.
The thermal switch is not reset to normal automatically 
even if the internal temperature becomes normal. Please 
reset the thermal switch following to the procedure below.
How to reset the thermal switch
1. Remove the cabinet top case.
2. Press the reset button on the thermal switch. 
Caution:
Before press the reset button, disconnect the AC cord 
from the projector.
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. 
Fuse
(F2003)
Fuse (F2003)
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 following type;
Fuse Part No.: T2190011500
TYPE VBS UBM 6.3A 250V (PF) FUSE
CONQUER. TYPE VBS UBM
How to replace the fuse
1.  The fuse is placed on the filter board. Remove the 
cabinet top following the "Mechanical Disassembly". 
Remote the cabinet top following the "Mechanical 
Disassembly".
2.  Take the fuse off from the fuse holder, and replace the 
new one with the specified type.
