This is my first post - so hello all - I am very much a novice at this new concept of LCD and plasma televisions! I hope I've got the right forum for my query! My faithful old telly that has lasted me for nigh on 20 years gave up the ghost recently so I've replaced it with a Sony KDL-40U2000 - and as I was decorating my lounge I thought I would also treat myself to a Home Theatre system! I purchased a Sony DAV-D2260. I've connected the two with an HDMI cable, and all seems well when playing a DVD ... I get wonderful surround sound. However, the surround sound does not work from the television channels. My question is - do I need another cable from the TV to the Theatre system? I hope this question makes sense!
