This section describes the simple maintenance procedures you
should follow to replace the lamp.
Replacing the Lamp
After your lamp has been operating for 1000 hours (1500 hours:
Eco mode) or longer, the “Status” indicator in the cabinet will
go on and the message will appear. Even though the lamp
may still be working, replace it at 1000 hours (1500 hours: Eco
mode) to maintain optimal projector performance.
CAUTION
• DO NOT TOUCH THE LAMP immediately after it has
been used. It will be extremely hot. Turn the projector
off, wait 90 seconds, and then disconnect the power
cable. Allow at least one hour for the lamp to cool
before handling.
• DO NOT REMOVE ANY SCREWS except the lamp
cover screw and three lamp case screws. You could
receive an electric shock.
• The projector will turn off and go into stand by mode
after 1100 hours (1600 hours: Eco mode) of service.
If this happens, be sure to replace the lamp. If you
continue to use the lamp after 1000 hours (1500
hours: Eco mode) of use, the lamp bulb may shatter,
and pieces of glass may be scattered in the lamp
case. Do not touch them as the pieces of glass may
cause injury. If this happens, contact your NEC dealer
for lamp replacement.
To replace the lamp:
1 Loosen the lamp cover screw until the screwdriver goes into
a freewheeling condition and remove the lamp cover. The
lamp cover screw is not removable.
