Problem
The image is stretched when
displaying a 16:9 DVD
Image is reversed
Lamp is burned out or makes
a popping sound
The OSD does not appear on
the screen
The remote control is not
operating smoothly or works
only within a limited range
Possible Solution
The projector automatically detects the input
signal format and maintains the aspect ratio of
the projected image according to input signal
format with a default setting.
If the image is still stretched, adjust the aspect
ratio as follows:
• If you are playing a 16:9 DVD, select 4:3
aspect ratio type on your DVD player.
• If you cannot select 4:3 aspect ratio type on
your DVD player, select 4:3 aspect ratio in
the Set Up menu in the OSD.
Select Set Up from the OSD and adjust the
projector mode.
When the lamp reaches its end of life, it may
burn out and may make a loud popping sound.
If this occurs, the projector does not turn back
on. To replace the lamp, see on page 35.
Try to press the Menu button on the control
panel or remote control for 15 seconds to
unlock the OSD. Check the Menu Lock on
page 28.
The battery may be low. Check if the laser
beam transmitted from the remote is too dim.
If so, replace with 2 new AAA batteries.
