installing a flat-screen TV

I wanted to install a flat-screen TV on the chimney wall (brest?) where the old gas fireplace used to be, now just an empty space. I thought it was the perfect space since the unused chimney provides a space to run the wiring invisibly. (I’d then have a carpenter make a little shelf thing in the fireplace opening for the cable box and stuff.) The electrician I’ve used in the past says it can’t be done. I didn’t quite understand the reason (I’m sort of a dolt when it comes to such things) but I thought I’d get a second opinion, as there really is no other space in the room where it can go. Anyone know if I can do that, and/or have a recommendation of another electrician to advise me? Thanks
