using DHCP and no DHCP server is
available.
Faulty Ethernet cable connection.
The unit is configured to use a static IP
address, but no IP address has been
entered in the address field.

Preferences : LCD Contrast setting. The default setting (6) is recommended.
If the colors on the display appear incorrect verify that the RGB cable is properly connected

data displays. Connect the necessary input or choose a different input as described in
"Selecting Input" on page 16.
