When we re-started our cable in Florida we were able to get HD TV by adding an HDMI cable to the box. The cable is on the outside of the wall and I would like to snake it inside the wall to the cable...
As I read it we are discussing an HDMI cable. These are about the worst cables to pull through existing work. BTDT & have the t-shirt. In my case I cut the existing paneling @ the edges of the cabinets. I ran the HDMI cable first (DO NOT DO IT LAST) I used 12awg building wire as a tag line, cut it 2½ times the run. Bead chain with a nut for weight & a strong magnet to find it can be a great aid for this type of work.
Good luck in getting it done.
