I've been having an issue with my coaxi cable giving off strong electrical shocks. In fact, it's fried two cable boxes, my TV and three cable techs.
I had out an electrician and he told me that it's probably the coaxi ground (grounded to the junction box by the meter) and said the the only wires running thru there are a hot and a neutral and that it could get getting back feed. He went on to test the outlets with a plug in meter and they all read "correct", so he claimed that it's not the wiring and that I should have them ground the cable to a water pipe.
SO, the cable company sent out two more techs who I briefed on everything I had been told by the electrician. They said that the ground is not the problem and that "company policy" states that they cannot ground to water, so they replaced all the cable in the apartment and outside. When they tried to hook up the tv they got the predictable shock.
They left telling me that they were sending out a supervisor this week. In the mean time, I started to do a little trouble shooting of my own. Here's what I found.
I took a look at all of the components that I have hooked up to my entertainment center and all of them with the exception of my PS3 are two prong plugs, the PS3 on the other hand is a three prong. I grabbed an old DVD player and hooked it up like normal to the television, the PS3 was also connected to the tv via HDMI. When I touched the coaxi to the back of the dvd player it shocked like hell. I then unplugged the HDMI from the PS3 to the tv and repeated the process,,,no shock at all. SO, I'm thinking that the PS3 must have a short of some type, but just to confirm I decided to pull the only other three prong source in my apartment, my pc. I ran the pc into the tv via S-video and had the hook up the same way to the dvd player. Touched the coaxi to the dvd and boom!,, unhooked the S-video from the pc and nothing.
So, I've concluded that the coaxi only gives off a shock when a grounded plug piece of equipment is hooked up. Does this sound like a wiring issue or could it really be a bad ground on the coaxi?
