• The lamp replacement message is set to appear after the following 
periods of time in order to maintain the initial brightness and quality of 
the projected images. 
·When used at high brightness: Approx. 2000 hours
·When used at low brightness: Approx. 3000 hours
• If you continue to use the lamp after this period, the possibility of the 
lamp breaking becomes greater. When the lamp replacement message 
appears, replace the lamp with a new one as soon as possible, even if it 
is still working.
• Depending on the characteristics of the lamp and on the way it has been 
used, the lamp may become darker or stop working before the lamp 
warning message appears. You should always have a spare lamp ready 
in case it is needed.
• Contact Epson for a spare lamp (see page 57
).
• Lamp life results vary depending on mode selected, environmental 
conditions, and usage. Lamp brightness decreases over time. Turn off 
this product when not in use to prolong the life of the projector.

removing the lamp cover; broken glass could fall out of the lamp area 
and get in your eyes.
• Wait until the lamp has cooled down sufficiently (about one hour) before 
removing the lamp cover.

Problem Solving
If you are having a problem with the projector, first check the projectors indicators and refer to Reading the Indicators below.
If the indicators do not show clearly what the problem might be, see “

The projector is provided with the following three indicators which indicate the operating status of the projector.
The following tables show what the indicators mean and how to remedy problems that they indicate.
If all indicators are switched off, check that the power cable is connected correctly and that power is being supplied normally.

 If the air filters are blocked, clean or replace them. See page 44
.
Press the [Power] button to turn the power back on. If this does not solve the problem and the projector

the projector, disconnect the power cable from the wall outlet, and contact Epson (see page 57
).
Lamp problem

If the lamp is not broken, put it back in and then turn the power on. If the lamp still does not turn on, replace 
it with a new lamp.
If this does not solve the problem, stop using the projector and disconnect the power cable from the 
electrical outlet. Then contact Epson (see page 57
).
If the lamp is broken replace it with a new lamp, or contact Epson for further advice (see page 57). If 
replacing the lamp yourself, be careful to avoid pieces of broken glass. (Projection cannot be carried out 
until the lamp is replaced.)
Check that the lamp and the lamp cover are securely installed. If the lamp or lamp cover is not securely
