I'm moving to a new place. Yesterday I connected the TV to the coax connector on the wall and accidentally short circuited it. I saw an electic arc and the TV tuner stopped working. I'm afraid it was busted. I touched the conductors and felt a shock.
Is it supposed to carry a voltage high enough to cause a shock? I later connected another TV that I don't care to bust and was able to get over the air channels. Should I use a surge protector in the future?
