There was a TV show of which I saw one episode. Details are fuzzy, but it was a small town and there were two police officers. Someone was demonstrating a new robot in town. It had a TV for a belly. It did useful things, but eventually it had some sort of internal meltdown and was going to explode. (Probably some nuclear explosion?) One of the cops is able to disconnect the battery at the exact second the robot is saying "Zeerroooooooooo---".
What show was this?
It was in color, if that's helpful. I'm guessing 70s, perhaps early 80s.
