VT77LP lamp replacement and time  

Be sure to replace the VT77LP lamp when the message “The lamp has reached the end of its usable life.

Please replace the lamp.”appears. If you continue to use the lamp after the lamp has reached the end of

its usable life, 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.

Allow a minimum of 10 seconds to elapse after turning off the projector.

Then turn off the main power switch, disconnect the power cable and allow 60 minutes to cool the projector

before replacing the lamp.

After your VT77LP lamp has been operating for 2000 hours (up to 3000 hours in Eco mode) or longer, the LAMP indicator in the

cabinet will blink red and the message will appear. Even though the lamp may still be working, replace it at 2000 (up to

3000 hours in Eco mode) hours 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 10 seconds, turn off the main power switch and then disconnect the power cable. Allow at least one hour for the VT77LP lamp to cool before handling.

• DO NOT REMOVE ANY SCREWS except the lamp cover screw and two lamp case screws. You could receive

an electric shock.

• The projector will turn off and go into stand by mode after 2100 (up to 3100 hours in Eco mode) hours of

service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000 hours (up to

3000 hours in 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
