Use and Replacement of Lamp
Lamp
The projector lamp has a normal operating time of approximately 1200 to 1500 hours, called the lamp
life. During the normal lamp life, the picture will be bright and the colors clear. If the lamp is used
beyond the normal lamp life, the picture will become dark and the colors poor. Always replace lamps
with new ones. Using an old lamp in the projector could cause a malfunction. When the power is
turned on, the LAMP indicator will light up red or a message will be displayed to indicate when it is
time to replace the lamp. Consult your dealer.
Lamp/Temperature Status LED Indicators
Lamp Exceed Service Hours — When this LED lights red continuously, it is warning you that the
lamp has exceeded 2000 service hours. Replace the projection lamp immediately.
CHANGE THE LAMP, AND RESET THE LAMP TIMER — The lamp has been operated
for 1200 hours.
CHANGE THE LAMP, THE POWER WILL TURN OFF AFTER 20 HOURS — The
lamp has been operated for 1479 hours, and the power will turn off after 20 more hours.
CHANGE THE LAMP! — The lamp has been operated for more than 1500 hours, and the
power will turn off automatically in 10 minutes.
All of these messages will not display for more than 3 minutes, but each message will be dis-
played whenever you turn on the lamp again.
Lamp is not well attached — When the LED blinks rapidly, it indicates that the lamp is not attached
properly.
Temperature is too high — When the projector’s internal temperature is too hot to operate safely, the
LED blinks slowly for one minute and the lamp goes off automatically.
If the LED light is off, it means that the projector’s lamp and temperature are operating under normal
conditions.
Caution
The LAMP indicator will light if the lamp becomes too hot. Turn off the power and let the projector cool
for 45 minutes. Turn on. If the LAMP indicator still lights up red, please contact your dealer.
