I recently bought a new tv and plugged it in to my cable box upstairs and then plugged the tv into the outlet. Then the tv downstairs went out and something in the main cable connecting equipment to the house (outside) blew up. The cable guy came out and said there was a short to ground in my NEW tv. He went on to say that this was the third one this week.
So, this morning, skeptical of his diagnosis, I checked voltage from the ground plug in the receptacle to the ground (outer metal covering) on my HDMI cable, which was plugged into the cable box. I read 118VAC. Seeing as how I can touch the outer metal covering of the HDMI cable without my hair standing up, I suspect I have voltage on my ground leg.
I have an old house with k&t wiring upstairs, but Romex downstairs. Seeing as how not everything that was plugged in was destroyed (only the stuff connected to CATV) the problem must be in that circuit. However, everything worked fine until I plugged in a new tv upstairs. The other tv was connected exactly the same way.
Im perplexed. Please HELP!!!
Thank you
