Hello everybody I'm new here but I am in need of some trouble shooting ideas. I bought the latest LG 3d LED 47" TV with compatible LG surround sound 5.1. I have it for over a year with this problem of " sometimes" the TV output of surround sound does not work! Yes I mean it works most of time but.. It conks out regularly. Weird I know. All other surround sound functions work eg: bluray sound, DVD sound, radio works but when I use the "ARC" function on surround sound( this is the function that allows sound through my system to TV only)it sometimes works and sometimes it doesn't! Pisses me off when u have the boys over to watch a game and the surround sound decides it's not gonna function that day. Now my HDMI is a cheap one, should I buy a new and better HDmi?? HELP!!!!
