Maintenance Indicators
■ The warning lights on the projector indicate problems inside the projector.
■ If a problem occurs, either the temperature warning indicator or the lamp replacement indicator will
illuminate red, and the power will turn off. After the power has been turned off, follow the proce-
dures given below.
About the temperature warning indicator
If the temperature inside the pro-
jector increases, due to blockage
of the air vents, or the setting lo-
cation, “
” will blink in the
lower left corner of the picture. If
the temperature keeps on rising,
the lamp will turn off and the tem-
perature warning indicator will
blink, the cooling fan will run for
further 90 seconds, then the power
will be shut off. After “
” ap-
pears, be sure to perform the fol-
lowing measures.
About the lamp replacement indicator
■When the lamp ex-
ceeds 1,900 cumula-
tive hours of use,
“
” will be displayed on the screen in
yellow. When the cumulative hours of use
reach 2,000, “ ” will change to red, the
lamp will automatically turn off and then
the projector as well. At this time, the
LAMP REPLACEMENT indicator will il-
luminate in red.
■If you try to turn on the projector a fourth
time without replacing the lamp, the pro-
jector will not turn on.
