For the last year or so, our cable tv has had an intermittent problem in which the video is covered by jagged rainbow static, and the audio is replaced by a VERY LOUD buzz. Seriously, vuvuzelas have nothing on it. Sometimes turning the tv off and then on again helps; other times not.

It's been like that for the last two weeks; at least, every time in the last couple of weeks I've turned on the tv it's been doing that.

I am a doofus.

It was the cable running from the cable box to the tv. At least it was Dale who discovered and fixed the problem, rather than a cable company tech. (I hadn't ever called them about it because it was always intermittent. And I didn't want to call about it this time because our house is squalorish and I couldn't stand the idea of someone else being in it.)
