my old tv was almost ten years old and was able to pick up my hd channels just fine. Now my brand new westinghouse won't pick them up what am I not doing right? I do not have a cable box, it's connected straight from the wall. Also my surround will only work through the mic jack on the back. But then it has to be surround only, sound won't come through the tv. If anyone can help me figure this out I would greatly appreciate it. Thanks in advance.
