I have a Sony 50" flat screen tv. All I have hooked up to it is a standard cable box. One day the sound went out. I was able to kinda tap the back and the sound came back. Then later it went back out for good. Will I have to have it repaired? Or is there away to hook up some other component like surround sound or some kind of external speaker to be able to hear sound again?
