Yep, that could do it. Video doesn't like an unterminated connection. You should have noticed a brighter than normal picture. That is what causes the hum.

I connected the cable box to a different TV and the problem was not replicated but I eventually found the cause of the problem and eliminated it.  The hum was related to a S-Video cable that was connected to an input on the TV but was disconnected at the other end.  Removing the S-video cable got rid of the hum.  No hum occurred when connecting video/audio from a dish receiver or a DVD player, just the cable box that did not like the S-Video cable.

Listen to Chuck, not to me.  I didn’t read the question carefully enough!

Some video equipment will automatically drop everything upon loss of video
and blank the screen.

If you are hearing a raspy buzz it could be that the video level is too
high. Does this happen when the picture has a lot of bright background in
it? If so, there's too much video level for some reason.
