How is it that our old TV gets fixed after I slapped it?

I just remembered when I was a kid(Im on my 30’s now) we had this old “box style” television. As it got older, there were times that a white thing will appear on the screen. You can still watch the show but its annoying. Imagine watching your TV while having a white curtain in front of it. One day, I got extremely furious because I was watching Smackdown and slap the side of the TV. Then, it returned to normal. I kept doing the same solution I discovered every time the white thing appears on screen until one day it stopped functioning. 😂

It could be a loose solder connection but probably not. More than likely, it was a corroded connector. Metal/metal contact with electric current is subject to fretting corrosion. Fretting is where tiny current paths move around on a microscopic scale giving corrosion a chance to disconnect them. A lot of engineering time and materials go into connector design to combat fretting but they still occasionally fail. Your consumer TV probably did not use the most expensive, gold plated beryllium copper high force, connectors. A little vibration is all it takes to restore connection.
