4. Troubleshooting
Problem Solution
Static or other video
interference
Make sure unit is properly grounded. Use the
grounding connector on the rear panel of the
chassis.
Front panel buttons not
working
Make sure the front panel controls are not
locked. Refer to the RS232 command list to
Lock/unlock the front panel.
Screen is blank Verify the screen output is not set to blank.
Verify your source is emitting a proper signal.
Verify cable connections.
Outside edges of the image
are cut off (image
cropping)
Some displays may experience cropping issues
especially when dealing with PC resolutions on
the VGA input. This is usually an issue with the
particular display being used. Unfortunately,
there is no guarantee every resolution will work
with every display. If you are having trouble its
best to try with a different display model or
manufacturer.
Serial control not working Verify the correct com port settings. Refer to
the RS232 section of this guide.
Video colors not correct Check the color settings of the device. Reset
back to the factory defaults to eliminate any
misconfiguration of the picture settings.
