The power cable management tie has nothing to do with fixing your problem. To echo Jeffrey, it is really poor form to ask a question & then insult the forum by attaching conditions to the answers. JVC's tube TV's were quite good, but when it comes to flat panel HDTV's, they are below par. From your description, it sounds as though the TV has died, and the only remedy is replacement. For someone who knows so little about the subject, your arrogance is quite misplaced.
