Depending on the size of the box, you may be able to “hang” it off the TV mount itself. Check that your remote is RF so it will still work without direct line if sight.

It is really easy to have someone do an inset shelf between two studs and then frame that, so you hav ea little hidden storage for the box and whatever.

Most remotes still use IR signals, so if you cannot see the cable box, you will not be able to control it.

Why do you need to this?

I think the Command Picture-Hanging Strips idea is the best one.

I don’t know if I understand, you want the tv to hang off the wall a bit so the box can fit back there? I guess get an articulating tv mount, pull it out a bit, and then stick the box back there. Probably with 4 screws (like pegs holding it from top and bottom) or command strips or something.

We just upgraded to Fios 1. The box is now much smaller and could fit behind the TV if I could figure out how to put it back there (tv hanging on wall). Anyone else able to put their Fios 1 behind the tv? If so, how did you do it?
