Lamp/Maintenance Indicators
Lamp
The lamp in this projector operates for approximately 2,000 cumulative hours, depending on the usage environ-
ment. When the lamp has been used for 1,900 hours, the LAMP REPLACEMENT indicator will light red and
“LAMP” will flash in yellow on the screen. It is recommended that the lamp be replaced after 1,900 cumulative
hours of use or when you notice a significant deterioration of the picture and color quality.
If the lamp has been used for 2,000 hours, the projector power will automatically turn off and the projector will
enter standby mode. If you turn on the power after the lamp has been used for 2,000 hours, “LAMP” will flash in
red on the screen and the power will turn off. See pages 30 and 31 for replacing the lamp. The lamp usage time
can be checked with the On-screen Display (see page 19).
• As the usage environment can vary significantly, the projector lamp may not operate for 2,000 hours.
CAUTION
• Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.

WARNING
indicator
• The warning lights on the projector indicate problems inside the pro-
jector.
• There are two warning lights: a TEMPERATURE WARNING indicator
which warns that the projector is too hot, and a LAMP REPLACE-
MENT indicator which lets you know when to change the lamp.
• If a problem occurs, either the TEMPERATURE WARNING indicator
or the LAMP REPLACEMENT indicator will light up red, and the
power will shut off. After turning off the power, follow the procedures
given below.
• If the TEMPERATURE WARNING indicator lights up, follow the above possible solutions and then wait until the projector
has cooled down completely before turning the power back on. (At least 5 minutes.)
• If the power is turned off and then turned on again, as during a brief rest, the LAMP REPLACEMENT indicator may be
triggered, preventing the power from going on. Should this occur, take the power cord out of the wall outlet and put it
back in again.
