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, outlets switched on, and 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 type (DVI-D, or analog) and color-space (RGB or YP
B
P
R
)
selected?
For analog output, is the correct synchronization type and polarity selected?
For analog output, 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.
Is the source HDCP encrypted? Then the display must have HDCP capability.
If these steps fail to resolve the problem, contact your home theater specialist for
assistance.
