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.
Circuit Protections
Fuses are located inside of the projector. If all the indicators are not lighting, 
the fuse (F2601) may be opened. If the STAND-BY indicator is lighting and 
others are blinking, one of the fuses (F2602) may be opened. If fuse (F2602) 
opens, the power supply to the LAMP1/LAMP2 will be cut off.  
Check the fuses as following steps.
The fuses should be used with the following type;
Location : F2601
Fuse Part No. : K5E153BZA003
TYPE 15A 250V FUSE
0215015.MXEP, LITTEL
How to replace the fuses
1.  Remove  the  cabinet  top,  main  board  following  to  "Me-
chanical disassembly".
2.  Remove the fuses  F2601, F2602 on the line filter board.
To install the fuses, take reversed step in the above.

Circuit Protections
There are the thermal fuses (SW903, SW904) inside of the projector to de-
tect the internal temperature rising abnormally. When the internal tempera-
ture around lamps reaches near 128˚C, the thermal fuse will open to cut off 
the power supply to the lamp power circuit.
If one of the thermal fuses opens, the projector cannot turn on the lamps. If 
the <STANDBY> indicator is lighting and others are blinking, one of the ther-
mal fuses may be opened. Thermal fuse replacement is required. The re-
placement of the thermal fuses must be done with a set of 2 fuses at once.

Sensor switche (SW6581)
Lamp cover sensor 
switch (SW6581)
This projector provides a lamp cover sensor switch (SW6581). The lamp cover sensor switch detects whether the 
lamp cover is closed securely. If lamp cover is opened or not closed completely, the drive signal to the lamp circuit 
is cut off. After opening the lamp cover for replacing the lamp ass’y, place the lamp cover correctly otherwise the 
projector cannot turn on.
CAUTION
DO NOT LEAVE THE PROJECTOR WITH THE AC POWER CORD 
CONNECTED UNDER AN ABNORMAL CONDITION. IT MAY RE-
SULT IN FIRE OR ELECTRIC SHOCK.
Indicators
The projector is shut down; and the <STANDBY> indicator is 
lighting and other indicators are blinking.
When the projector detects an abnormal condition (SW903, SW904, - opens, 
or SW6581 - opens), it will be automatically shut down to protect the inside 
of the projector and the <STANDBY> indicator lights on and other indicators 
blink. In this case, unplug the AC power cord and check that the filter car-
tridge and lamp cover are installed securely, and the plug it, and turn on the 
projector once again to verify operation. If the projector cannot be turned on 
and these indicators are still lighting and blinking, unplug the AC power cord. 
See the troubleshooting chapter.
STANDBY indicator lights 
on and other indicators 
blink.
