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 assy, place the 
lamp cover correctly otherwise the projector can not turn on.
Thermal fuse (SW902)
There is a thermal fuse (SW902) inside of the projector to detect the 
internal temperature rising abnormally. When the internal tempera-
ture around lamp reaches near 113˚C, the thermal fuse will open to 
cut off the power supply to the lamp power circuit.
If the thermal fuse opens, the projector cannot turn on. Thermal 
fuse replacement is required. 
This projector provides the following circuit protections to operate in safety. If the abnormality occurs inside the pro-
jector, it will automatically turn off by operating one of the following protection circuits.
Fuse
(F601)
Circuit Protections
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 following type;
Fuse Part No.: 423 035 3004
TYPE T8AH 250V FUSE
LITTEL FUSE INC. TYPE 0215008.MXEP
or
How to replace the fuse
1.  The fuse is placed on the AC 1ST FILTER board. Remove the 
cabinet top, MAIN&AV board following the "Mechanical Disas-
sembly" . 
2.  Take the fuse off , and replace the old one with the specified 
type.

Circuit Protections
The projector will be automatically turned off when the internal temperature of the projector is abnormally high, or the 
cooling fans stop spinning, or the power supplies in the projector are failed.
Warning temperature and power failure protection
The projector is shut down and the WARNING indicator lights red.
When the projector detects an abnormal condition, it is automatically shut down to protect the inside of the projector 
and the WARNING indicator lights red. In this case, unplug the AC power cord and reconnect it, and then turn the 
projector on once again to verify operation. 
WARNING
DO NOT LEAVE THE PROJECTOR WITH THE AC POWER CORD CONNECTED UNDER AN 
ABNORMAL CONDITION. IT MAY RESULT IN FIRE OR ELECTRIC SHOCK.  
ü 
Note:
- If the WARNING indicator lights red, it may defect the cooling fans or power supply circuits. Check fans operation  
  and  power supply lines referring to the chapter “Power supply & protection circuit” and "Fan control circuit" in the  
  Chassis Block Diagram section.
When the temperature inside the projector reaches a certain level, the projector will be automatically shut down to 
protect the inside of the projector and the WARNING and ON(G)/STANDBY(R) indicators start blinking. When the 
projector has cooled down enough (to its normal operating temperature), the ON(G)/STANDBY(R) indicator stops 
blinking and lights red, The projector can be turned on again by pressing the  
button.
ü
Note:
The WARNING indicator continues to blink even after the temperature inside the projector returns to normal. When 
the projector is turned on again, the WARNING indicator stops blinking.
Check items
- Remove dust around  the air filter.  
  
- Ventilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation slots are          
  not obstructed.
- Check if projector is used at higher temperature.
The projector is shut down and the WARNING indicator is blinking red.
