NOTE: Immediately after turning on the projector, screen flicker may occur. This is not a fault. Wait 3 to 5 minutes until the lamp
lighting is stabilized.
When the Lamp mode is set to Eco, the Lamp indicator will light green.
If one of the following things happens, the projector will not turn on.
•If the internal temperature of the projector is too high, the projector detects abnormal high temperature. In this
condition the projector will not turn on to protect the internal system. If this happens, wait for the projectors internal
components to cool down.
•When the lamp reaches its end of usable life, the projector will not turn on. If this happens, replace the lamp. See
page 107.
•If the lamp fails to light, and if the STATUS indicator flashes on and off in a cycle of six times, wait a full minute and
then turn on the power.

ing that might appear and to reduce video noise, dot interference or cross talk (this is evident
