Are the image signal format
settings correct?
If a composite video or S-Video is being input
If projection does not occur when the "Video Signal" menu
command is set to "Auto", select the signal format that matches the
signal source.
"Settings" - "Input Signal" - "Video Signal" p.34
If the signal source is connected to the [Component] input port
If projection does not occur when the "Component" in the "Input
Signal" menu command is set to "Auto", set the signal format that
matches the signal that is being projected from the connected
equipment. "Settings" - "Input Signal" - "Component" p.34
Does the mode match the
frequency and resolution of the
image signals?
Use the "Resolution" menu command to check the signals being
input, and check the "List of Supported Monitor Displays" to make
sure that the signals are compatible.
"Info" - "Resolution" p.29
"List of Supported Monitor Displays" p.49
Are the cables connected
correctly?
Check that all of the cables required for projection are securely
connected. p.12
Has the correct video input port
been selected?
Press , , or on the remote control or on
the projector’s control panel to change the image source. p.15
Is the power for the connected
equipment turned on?
Turn the power on for the devices.
Are the image signals being
output to the projector?
If the image signals are only being output to the computer's LCD
monitor, you need to change the output.
For some computer models, when the image signals are output
externally, they no longer appear on the LCD monitor.
Computer documentation, under a title such as "External
output" or "Connecting an external monitor"
If the connection is made while the power is already turned on, the
function [Fn] key that switches the computer's video signal to
external output may not work. Turn the power for the projector and
the computer off and then back on again. p.14
Has the focus been adjusted
correctly?
Adjust the focus. p.16
Is the lens cover still attached? Remove the lens cover.
Is the projector at the correct
distance?
The recommended distance from the projector to the screen is
within 87 to 956 cm (2.8 to 31.4 ft.) for a screen size of 16:9, and
106 to 1170 cm (3.5 to 38.4 ft.) for a screen size of 4:3. Set up the
projector so that the projection distance is within this
range. p.10
