■ The maintenance indicators (power, lamp and temperature warning indicators) on the projector will let
you be aware of problems inside the projector. If any of the indicators illuminates, follow the relevant
procedures given below.
About the temperature warning indicator
If the temperature inside the
projector increases, due to
blockage of the exhaust or
intake vent, or the setting loca-
tion, “
” will blink in the lower left corner of
the picture. If the temperature keeps on rising,
the lamp will turn off and the temperature warning
indicator will blink, the cooling fan will run, then
the projector will enter the standby mode. After
“
” appears, be sure to perform the measures
described on the table below.
About the lamp indicator
■ When the remaining lamp
life becomes 5% or less,
(yellow) and “Change
The Lamp” will be dis-
played on the screen. When the percentage
becomes 0%, it will change to
(red), the lamp
will automatically turn off and then the projector
will automatically enter standby mode. At this
time, the lamp indicator will illuminate in red.
■ If you try to turn on the projector a fourth time
without replacing the lamp, the projector will
not turn on.
