Troubleshooting::

No Picture::

Ensure that the video source is on and generating a signal.
Ensure that the TV and the modulator are tuned to the
same channel. 

Herringbone Interference on Modulated Channels::

Ensure that the channel that you are modulating to is
completely vacant. Distant UHF stations may sometimes
appear open but will cause interference if you try creating
a new channel at the same frequency.
