Meaning
The temperature inside the projector is too high
for some reason or the outside air temperature is
higher than the operating range. If the problem is
inside the projector, check whether the projector
is installed and operating normally, unplug the
projector from the power outlet to cool down the
projector interior and then restart projection. If the
air intake or exhaust vent is blocked, remove the
obstacle. If the air filter is clogged, replace it
(P191). If the same warning occurs again, there
may be a malfunction in the projector.*
The light source does not illuminate. Restart the
projector and check projection. If the light source
does not illuminate after this, the light source
drive circuit may be damaged.*
The air filter is not installed correctly. Install the
air filter correctly and restart the projector. If the
same warning occurs again, there may be a
malfunction in the projector.*
There may be a malfunction in the cooling fan or
another component. Unplug the projector from
the power outlet, then plug it back into the outlet
and turn on the projector again. If the same
warning occurs again, there may be a
malfunction in the projector.*
Abnormal voltage is applied to some parts in the
power supply or another failure may have
occurred. Unplug the projector from the power
outlet, then plug it back into the outlet and turn on
the projector again. If the same warning occurs
