Ok so recently I got directv the tech came out and installed it about two weeks ago on the day of the install the tech fried three hd receivers two in my bedroom and one in my living room. Come to find out I had three electrical sockets with reverse currents in my bedroom the tech tells me this caused the receivers to fry and that I should have electrician come out to fix it. So he gets an extension cord to plug the receiver up to a good socket and everything is fine with the bedroom receiver now so he moves on to the living room and he blows another receiver in there but this time there isn't any reverse currents in electrical sockets. He goes ahead and hooks up another receiver and everything is fine. I call an electrician to fix the reverse currents in my bedroom and to check out the electical sockets in my other rooms and everything checks out fine. A couple a days ago the receiver in my living room frys again and call directv to have a tech come out and replace it. So the tech comes in and starts hooking up the new receiver and as soon he hooks up the HDMI cord from the receiver to my tv it pops fire and my tv goes off and won't come back . The tech says I have electrical problem going on and that it wasn't his fAult my tv was fried. Here's the problem I had my tv, blu ray, and Xbox 360 hooked up I didn't have a problem but as soon as directv receiver is hooked up theres a problem. I had an electrician come out he said everything is ok. So what should I do ?
