As of yesterday I am the proud owner of a Sony KDF-55WF655 and I am loving it! I have regular analog cable (coaxial from wall into TV) and no external antenna. Based on my location and the poor AM/FM reception I figured there would be little hope of getting OTA HD even with an antenna on the roof. To my surprise after running the auto-channel setup it found all the Digital and HD stations in my area (as per antennaweb.com). I now see what all the fuss is about - the HD picture on these TV is beautiful. I was up to 2AM watching HD-Discovery and PBS-HD nature shows. I'm not complaining but, how do I get these channels? When I hit the ANT/Cable button on the remote (to go to Antenna input) I get nothing. In regular cable mode I'm in HD heaven!
