Is it time to replace the lamp?
When the lamp is nearly ready for replacement, the images become darker and the color quality becomes poorer. When
this happens, replace the lamp with a new lamp.
s
Has the projector been left unattended without an image signal being
input?
If no operations are performed on the projector while no image signal is being input, the lamp is automatically dimmed
to prevent electricity being wasted. When an image signal is input or an operation is performed on the projector, the
projector returns to the previous brightness setting.
Is
Sleep Mode
set to
On
?
If no operations are performed on the projector for approximately five minutes while no image signal is being input, the
lamp is automatically dimmed to prevent electricity being wasted.

Remedy
Did you press the [
] button on the remote control or the [
t
]
button on the control panel?
Press the [
] button on the remote control or the [
t
] button on the control panel to turn on the projector.
Are the indicators switched off?
The power cord is not connected correctly or power is not being supplied.
Disconnect and then reconnect the power cord.
Check that your electrical outlet or power source is functioning correctly.
Do the indicators turn on and off when the power cord is touched? There is probably a poor contact in the power cable, or the power cable may be defective. Reinsert the power cable. If this
does not solve the problem, stop using the projector, disconnect the power cable from the electrical outlet, and contact
your local dealer or the nearest address provided in the Epson Projector Contact List.
