The lights on top of the projector indicate the projector’s 
status and let you know when a problem occurs. 

If no lights are on, make sure the power 
cord is connected securely both at the 
power outlet and the projector. If you have 
just replaced the lamp, make sure the cover 
is securely fastened

.

projector is in sleep mode. Press the Power 
button to turn it on.

When the power and temperature lights 
are flashing, the projector is getting too hot 
and is in rapid cooling mode. You can 
continue running it in this condition, 
however, verify that the air filter is not 
clogged. Clean or replace it as described on 
page 19.

Make sure the room temperature is not 
above 95 

°

F (35 

°

C) and there is plenty of 

space around and under the projector for 
ventilation.

When the power and temperature lights 
are red, the projector has overheated, 
which turns off the lamp automatically. 
Wait about 5 minutes for the projector to 
cool, then unplug the power cord. 

Verify that the air filter is not clogged. 
Clean or replace it as described on page 19.

Make sure the room temperature is not 
above 95 °F (35 °C) and there is plenty of 
space around and under the projector for 
ventilation. Then plug the power cord back 
in and press the 

P

Power

 

button. 

If the projector continues to overheat, 
contact EPSON for help.

When the 

P

power light is red and the 

temperature light is flashing red, there is a 
problem with a fan or temperature sensor. 
Unplug the power cord and contact EPSON 
for help.

When the 

P

power light is green and the 

lamp light is flashing orange, the lamp has 
been used for at least 1900 hours. To 
ensure continued operation, you should 
replace it as soon as possible (see 
page 19).

When the 

P

power light is red and the 

lamp light is flashing red, the lamp has 
burned out. Replace it as described on 
page 19.

If these lights come on after replacing the 
lamp, make sure the lamp is fully inserted 
and the lamp cover is attached. 

If all three lights are red, the projector has 
an internal problem. Unplug the power 
cord and contact EPSON for help.
