We bought a Sony picture tube HDTV (KV40XBR700S) in December of 2001. It works perfectly -- we've never had a problem and the HD is fabulous. We have never seen a better picture on plasma or LCD or any other format.
The question is this: what can we do to make this TV last longer -- specifically, should we leave it on if it is not going to be used for a while, like half an hour or an hour, or is it better to shut it off and re-start it?
Does the process of turning it on and off cause more wear and tear than leaving it on?
Your advice would be appreciated.
