When Having Some Trouble
If you are having a problem with the projector, first check the projectors indicators.
The projector is provided with the following three indicators. These indicators alert you to problems with projector 
operation.
The following tables show what the indicators mean and how to remedy problems that they indicate.
    : lit   : flashing   : off
Indicator statusProjector statusProblem and remedyReference 
page
Internal problem Stop using the projector, disconnect the power cord from the 
electrical outlet, and contact your dealer.
Fan problem/Sensor 
problemStop using the projector, disconnect the power cord from the 
electrical outlet, and contact your dealer.
Lamp problem/
Lamp cover problemReplace the lamp with a new one.
When replacing the lamp, check that the lamp and the lamp cover 
are securely installed. If the lamp or lamp cover is not securely 
installed, the projector power will not turn on.p.48
Lamp operating 
errorThis can happen when the main power switch at the rear of the 
projector was turned off before the cool-down
 period had 
finished the last time the projector was turned off, and it was then 
turned back on again before one hour had passed.
When turning off the projector, wait 2 minutes. After about 2 
minutes, the cooling fan will stop. When the cooling fan stops, 
turn off the main power switch and then turn it back on again. 
When the main power switch is turned back on, the projector will 
return to its previous state, so press the [STANDBY/ON] button 
on either the remote control or the projectors control panel to 
turn it back on. If the lamp operating error happens again when 
the power is turned back on, remove the lamp and check if the 
lamp is broken. If it is not broken, reinstall it. If it is broken, 
replace it. Then turn on the main power switch at the rear of the 
projector and press the [STANDBY/ON] button on either the 
remote control or the projectors control panel.
If the indicators still show a problem, stop using the projector, 
turn off the main power switch, disconnect the power cord from 
the electrical outlet, and contact your dealer.p.48
