Replacing the Lamp 
The projection lamp typically lasts for about 2000 hours of use 
(in High brightness mode) or 3000 hours (in Low brightness mode). 
It is time to replace the lamp when: 
The projected image gets darker or starts to deteriorate.
The 
 warning light is flashing red at 0.5-second intervals. 
The message 
Lamp Replace
 appears on the screen when the 
lamp comes on. To maintain projector brightness and image 
quality, replace the lamp as soon as possible.
Contact your dealer or call EPSON at (800) 873-7766 in the United 
States for a replacement lamp. Request part number 
V13H010L27
.
In Canada, please call (800) 463-7766 to locate a dealer. 
Follow these steps to replace the lamp:
1. Turn off the projector.
2. When the power light stops flashing and remains orange, unplug 
the power cord.
3. If the projector has been on, allow it to cool down for at least half 
an hour (or until the lamp is cool). 
4. Turn the projector upside-down to access the lamp compartment.
5. Use the screwdriver included with the replacement lamp to slide 
the edge of the lamp cover towards the side of the projector. Then 
lift off the cover.
