Larry, He can not hook is cable directly to HD INPUT 4(by-passing the box)..I'm not sure what he's saying here. You will almost have to have something to input an HD signal into those jacks...a DVD player may be a good choice to see if the problem is the HD cable box. Also, Hitachi offers free acces to their manuals and technical support.
