Troubleshooting
Be sure that the power cord of the projector is connected.
Be sure that the proper input source is selected.
Check that the connectors are properly connected to the ports
at the back of the projector.
Check the Remote Control batteries.
Be sure that the <Color>, <Brightness> settings are not at their
lower limit.
Adjust the <Tint> and <Contrast>.
Adjust the focus.
Check that the projection distance is either too far or too near
to the screen.
If a strange sound continues, contact our service center.
Refer to Corrective Actions According to LED Indications.
Because noise may occur when using your PC, adjust the fre-
quency of the screen.
Check the operating status for the external device and check
whether the adjustment items, such as the <Brightness> and
the <Contrast> have been changed correctly in the <Mode>
command screen of the Projector menu.
Be sure to properly connect the external devices. Check the
connection cables again.
As mentioned above, check the adjustment items such as the
<Brightness>, <Contrast> and <Color> in the menu.
If you want to restore various settings to their factory defaults,
run <Factory Default>from the menu.
Set the resolution and the refresh rate for your PC display to
800x600 and 60Hz respectively.
See the "2-7 Setting up the PC Environment" section here in
for details on the setting.
Check the audio format of the concerned video file.
The sound effects are not available for non-supported formats
