So I have multiple TVs in our house but recently had to buy a new one.  We have cable but no cable boxes.  I have straight coax cables going into the back of the TVs so I can get the HD channels for the networks (4-1, 6-1, etc.).  On the new TV, however, I cannot get the -1 HD channels from the networks but I can get them from the CW and PBS.  I’ve searched everywhere for a reason/solution but haven’t found anything yet.  Is anyone familiar with this and do you have a solution?
