The last time I watched TV regularly, I only watched Star Trek: The Next Generation (not yet in rerun). But it was an old TV and had a bad electrical connection somewhere. It had something like a 14" screen.
But I had a belt that would just reach from where I sat. I would hit the TV with the belt when the connection got wonky. I finally realized that I was whipping my TV when it did not please me, so I tossed it in the dumpster rather than risk somehow corrupting myself.
