-
Improper termination of the Program Output of
the Video Toaster card.
Solution: Properly terminate the output with 75ohm
terminator or if the monitor they are using has
a 75ohm termination switch make sure the switch
is on.
If termination is on, but the output is hot anyway,
you may need to have the termination level in the
device (monitor or deck) checked by qualified service
staff. If the termination level is incorrect, even
by a small amount, then the output from the Toaster
will be hot (One user reported that a level of
76.2 Ohms produced the problem).
-
A signal passing into the Toaster is unterminated.
Check the Toaster Preferences screen to see that
termination is turned on for the input. Unless
you are using a T-connector on it, each Toaster
Input should have termination turned on. If you
are using a T-connector, and the video is hot,
then the signal may not be properly terminated
at the end device. Check that device and terminate
properly.

A defect or malfunction of the Flyer BNC (4000)
or Flyer cable (2000).
Solution: Replacement of the BNC or cable.
-
Video level of the source being used could be
too hot entering the inputs, especially if a TBC
is being used to correct the source.
Solution: Test input video with a Waveform and
vectorscope to insure that input video is proper.
Adjust to proper levels.
-
Luma gain is set improperly on source deck or
TBC.
Solution: Adjust setting until problem is gone.
-
Horizontal position of video is off, causing active
video top be present where the Toaster expects
blanking or "back porch".
This happens commonly with TBCs that "kick
up" the overscan of throughput video. The
solution: Adjust setting to eliminate problem.
