We literally had a TV where you had to do this. It was a black and white set and it was ancient even when I was a kid. My parents refused to buy a new one though so we had this thing until the mid eighties. They had bought it some time in the sixties. Sometimes the picture went away and you had to hit it in a certain place to bring it back.

That's usually just a pin making bad contact with the socket due to oxidation. Reseating all of the tubes usually fixes it. If not, then it's probably a cracked solder joint.

Thanks for telling me. Only 40 years too late ;)
