TROUBLESHOOTING
No sound
Out of focus
Top/bottom or left/right reversed
Cause
Countermeasure
The audio cable is not connected
properly.
Check whether the audio cable is connected properly.
(P24, 43)
The [MUTE] function is selected.
Press the [MUTE] button on the remote control. (P40)
The volume level is adjusted to the
minimum.
Adjust the [VOL+] button on the remote control or top con-
trol to adjust the volume level. (P40)

Cause
Countermeasure
The image is out of focus.
Adjust the focus. (P30)
The lens cap is not removed.
Remove the lens cap. (P92)
The distance to the screen is too
short.
Check whether the distance to the screen is proper.
If the distance is shorter than about 3.9' (1.2 m), the image
cannot be brought to a focus. (P20, 85)
The projector is not placed straight in
front of the screen.
Check whether an image is obliquely projected to the
screen. A slight error in the projection angle can be cor-
rected through keystone adjustment. (P21, 31)
The projector has been moved to a
place where the difference in tempera-
ture is large.
When the projector is moved from a low-temperature
place to a high-temperature place, dews may form on the
lens. Dews will evaporate a while later and the projector
will be able to project a normal image.
Cause
Countermeasure
An image is projected with its top and
bottom or left and right reversed.
The ceiling mounted/rear projection setting is incorrect.
Check the "Image flip H/V" setting in the Display settings
menu. (P61)
