Maintenance Indicators
• The warning lights on the projector indicate problems
inside the projector.
• There are two types of warning lights: a TEMPERATURE
WARNING indicator that warns you when the projector
is too hot, and a LAMP REPLACEMENT indicator that
warns you when to change the lamp.
• If a problem occurs, either the TEMPERATURE
WARNING indicator or the LAMP REPLACEMENT
indicator will light up red. 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, for example during a brief rest, the LAMP REPLACEMENT indicator may
be triggered, preventing the power from going on. Should this occur, unplug the power cord from the wall outlet and plug it
back in again.
