Meaning
The temperature inside the projector is too high for some rea-
son or the outside air temperature is higher than the specified
one.
If the problem is inside the projector, check whether the pro-
jector is installed and operated normally, turn off the projector
to cool its inside, and retry projection. If the same warning
occurs again, the projector may be defective. Contact your
dealer.
The lamp has burnt out. Replace the lamp with a new one. If
the same warning is experienced again, the lamp drive circuit
may be defective. Contact your dealer.
The lamp cover is open. Check whether the lamp cover is
installed correctly. If it is installed correctly, the lamp cover
detection switch may be defective. Contact your dealer.
The cooling fan or another component may be defective. Con-
tact your dealer.
The abnormal voltage is applied to some parts in the power
supply or any other problem has occurred in the power supply.
Contact your dealer.
Some of the functions may be defective. Turn off the projector
