I bought the TV from a pawn shop so have no book and am using a universal remote. I accidently messed up the original channel settings and had to reset it. Well, it reset with digital channels which means it does not follow the channel numbers. I am trying to move it into my brother's room and hook it upto a digital cable box and it will not accept a signal. I have tried setting it to cable and then I tried to set it to antenna and just sits there saying "no signal". I do not know what to do to get it to accept the signal from the digital box. It accepts the signal directly from the cable but will not accept the digital box signal.
