I recently bought a new flat screen tv that I hooked up directly to the
cable line coming into the house( no cable box). The sound quality was
crummy so I returned it and went with a different manufacturer and still
the sound quality is bad...sounds like its coming from an empty can,
that is, it sounds hollow. I am wondering if its because I don,t have a
cable box. I tried to tweak the bass and treble but it still sounds
hollow, for lack of a better word. Anyone else have a similar problem?

Thanks, CJ
