Problem: The image is stretched when displaying 16:9 DVD.
The projector automatically detects 16:9 DVD and adjusts the aspect
ratio by digitizing to full screen with 4:3 default setting.
If the image is still stretched, you will also need to adjust the aspect
ratio by referring to the following:
Please select 4:3 aspect ratio type on your DVD player if you are
playing a 16:9 DVD.
If you can't select 4:3 aspect ratio type on your DVD player, please
select 4:3 aspect ratio in the on-screen menu.
Problem: Lamp burns out or makes a popping sound
When the lamp reaches its end of life, it will burn out and may
make a loud popping sound. If this happens, the projector will not
turn on until the lamp module has been replaced. To replace the
lamp, follow the procedures in the "Replacing the Lamp". See
page 29.
