The projector will not turn back on even 
when pressing the <POWER ON> button on 
the remote control or the <

the side control. When the projector returns 
to the normal operating temperature, the 
standby indicator <ON(G)/STANDBY(R)> will 
change to on. The projector will turn back on 
when pressing the <POWER ON> button on 
the remote control or the <

A problem has been detected within the 
projector.
The projector will not turn back on even when 
pressing the <POWER ON> button on the 
remote control or the <

> button on the side 

control. Remove the power plug from the outlet, 
and plug it back in again.
If the power turns off, or the indicator turns on 
or flashes again, remove the power plug from 
the outlet and contact your dealer to request an 
inspection and repair. Do not leave the projector 
plugged in with the indicator on or flashing. 
Doing so may cause a fire or electric shock.

*1: The indicator will flash in approximately 0.5-second intervals.

Projector provides a protection circuit to prevent the secondary failure when the power failure, fans failure or tempera-
ture failure occurs on the projector. The power failure detection lines "PF_3.3V_AD", "PF_3.3V_GAM", etc. are con-
nected to the main power supplies. When the failure occurs, IC301<SYSTEM CONTROL> receives an error informa-
tion through IC5201<FPGA>,  and then outputs the signal "LAMP_DC_ON" from pin 32. The signal "LAMP_DC_ON" 
is supplied to power supply circuit to control the power supply operation.
