There is a member at Youtube "
schonhans1" (Simon Peter Schonhans), who's posted videos he's
captured of similar anomalies.
I haven't watched a lot of this member's Youtube videos, but he has in fact captured anomalies with his television set of the type you've mentioned
- more specifically, visual anomalies, as well as light balls leaping from people at him, etc.
He talks a lot about MK Ultra / mind control, CIA, FBI and cults, etc., and appears to be suffering from schizophrenia; although, I speak not having
any sort of mental health background.
What is fascinating is that some of the subjects he speaks about include verifiable information, and some of his videos compellingly back up at least
the fact that something paranormal / out of the ordinary is happening to him...
What's also very strange, and this is related, are accounts of people suffering from what they're calling
"
gang stalking" who report - and also videotape - this
strange television phenomena.
The victims of gang stalking often talk about regular people, seemingly involved in some sort of cults, involved in high tech, or paranormal assaults,
or surveillance, including shining odd lights into people's houses, messing with the television image, etc.
There is something truthful behind this and it echoes what's been said about cults / multidimensional mischief makers behind our governments,
churches, entertainment industry, etc.
It's all very bizarre...
