Noise is heard
Check
Action
Refer to
Is the exhaust vent blocked?
Is the unit used near a heater or air-
conditioner?
Check the installation condition of the projector.
When the surrounding temperature of the projector is high,
the fan revolution speed increases to protect the projector
unit, hence a louder operating sound.
P. 20
Are you viewing 3D video images?
“LD Power” is set automatically to “High” to ease viewing
of 3D video images, hence a louder fan operating sound.
If you are bothered by the sound, set it to “Low”.
P. 57
Is “LD Power” set to “High”?
Setting “LD Power” to “High” increases the fan rotation
speed, and noise would be louder as a result.
P. 57
Is the “8K e-shift” setting for “MPC”
switched?
Switching sound is generated. This is not a malfunction.
