If the recommended actions listed below do not result in satisfactory operation, please
consult your Dealer or contact the FSR Technical Support Department directly by phone
at 973-785-4347 or by email at [email protected].

the output
monitor.

wrong on the
output monitor
Too much
smearing
No color on the
output monitor,
only a black and
white image
None of the controls
appear to function
If pressing the power switch does not cause the
power LED to light, check that the proper AC Power
Cord is properly connected. If the Power LED is
illuminated, check that there is a correct Video Input
signal and that the display device connected to the
output is switched on and set to the correct input and
its Brightness and Contrast are set correctly. Check
to make sure the unit has been switched to the
correct output pin mode – HD15 or BNC.
Try adjusting the Color, Tint, Contrast and Brightness
settings on your display. These are usually set up for
viewing computer images, which may be somewhat
different from viewing images that have been up-
converted from video. Make sure the correct output
format is set (RGBHV or YCbCr). Make sure your
output cable assembly is not faulty, which could
prevent either the Red, Green or Blue signal from being
passed through the cable.
Smearing usually occurs when a Composite Video input
is used and is generally unavoidable, unless you can
switch to using S-Video. Using good quality video cable
will help towards reducing this affect. Smearing that
may not be noticeable on a small video monitor may
become objectionable on a large screen video projector.
Check the condition of the cables being used. A faulty S-
Video cable can often cause a black and white image.
Ensure that the color controls on your computer monitor
or video projector are all set correctly. Ensure that the
color adjustment on the Video Scaler is not adjusted
completely down. It may be necessary to reset the video
levels via the Menu functions.
The ON SCREEN DISPLAY (osd) has been turned off and
the front panel has been locked out. Just depress both the +
and - buttons for 3 seconds to unlock the front panel and then
the osd will be enabled.
