A:AnswerSo I already had my mounts installed the guys just put my TV up and set it up for me and it was $100 I think it’s 200 to do the mountain as well but well worth it
A:AnswerIn most cases you will be able to speak with a home theater employee and they can sell you everything you will need. Purchase a long enough coax cable for your xfinity service. You will need one from the wall to the cable box and the employee will sell you the mounting services plus any additional cables you will need such as a long hdmi cable.
A:AnswerI don't know what they would charge, but Best Buy tas a swivel base mount that uses wall mount features that would really make your job lot easier and would be able to work on futurer set replacements, too.
A:AnswerYes the service squad mounts the TV after measuring and securing the mount to the wall. They also connect all the cables to the TV and cable box and DVD player.
A:AnswerA lot! Best Buy does not do electric, nor would I trust them to anyway. If you're okay patching some drywall, buy a Datacomm power relocation kit. It's UL listed and you can run the wiring yourself to an existing outlet.
