A&E HD, DSC HD, and HGTV HD are coming in distorted on a new box I just received. Initially BTN HD and ESPNU HD were not coming in at all. I removed the cable connector from the wall and installed a new one. Now those two channels come in fine. These others channels though are coming in distorted. Anyone have any suggestions? Also curious if Verizon charges for a tech to come out and resolve the issue.
