I have a t.v. that's connected to converter box with a coaxial cable. When I turned it on and t.v. message said 'no signal,' I noticed the cable was loose. I noticed the pin that's in the center of the cable (end that connects to t.v.) was bent all the way down and to the side. Managed to fix it, but cannot figure out how it happened. Would anyone here know how it could've become bent like that? As the pin's INSIDE, I don't know any explanation other than someone tampered with it. Is there some other explanation?
