Troubleshooting
Following are some common problems, along with suggestions to help resolve them.
Also, check the www.lumagen.com website for updated troubleshooting information.
No picture is visible:
Are all components properly connected to power and power outlets switched on?
Are all components powered on?
Are all of the video cables connected to their respective inputs and outputs?
Is the menu visible when the MENU button is pressed? If it is, the problem is with
the inputs. If it is not, the problem is with the output connections or settings.
Does the display support the programmed vertical and horizontal timings?
Is the correct output color space (RGB or YP
B
P
R
) selected?
Is the correct synchronization type and polarity selected?
If used, are the separate horizontal and vertical sync signals misconnected? For
VGA breakout cables, the signal order at the BNC connectors is generally red,
green, blue, horizontal-sync and vertical-sync, but this may vary.
If there is still no picture, press

on the remote to reset
parameters to factory defaults. Then connect an analog VGA computer monitor to
the video output. After the monitor warms up, press the
MENU button on the
remote control. The on-screen menu should be visible. Select each input in turn to
make sure they are working properly. If the inputs work properly, the problem is
with the display, display cabling, or output setup.
If these steps fail to resolve the problem, contact a home theater specialist for
additional assistance.
Objects appear to be too tall or too wide:
Make sure the video output aspect ratio is programmed correctly.
Make sure the correct input aspect ratio is selected.
Make sure input size is adjusted correctly.
Make sure the “television aspect ratio” setting is 16:9 in the setup menu of all
source devices that support this feature (DVD players, satellite receivers, etc.),
even if the screen is not 16:9.
Colors are way strange:
Is the correct output color space (RGB or YP
B

) selected?
