Question DetailsAsked on 12/12/2015

Question about wall mounting my TV/cable routing on/in a drywall?

Not sure if this is the right place to ask this kind of question, but giving it a try.
I want to wall-mount a TV on my wall. Previous owner had a cable hole at the top and there are 3 holes
right next to each other at the bottom.(Not sure why they did 3 holes)
I bought a TV wall mount kit from HomeDepot(
I am wondering, if I should fill up the bottom 3 holes with drywall watch and then after it dries out, make a single new hole on it for the power socket of the kit or make a 4th hole little above the existing 3 holes.

Any suggestion? Is it advisable to make hole on a drywall patch area(would it provide enough strength to hold the plate) or any other solution?

Not quite sure I visualize your situation fully - but I would guess the three holes down low may have been from attempts to feed the cable to the prior wall mounting location - or one or may have gone into a stud or on the wrong side of a stud so took 3 tries to get the cable fed right. Or he dropped the wire from above and was trying to fish for it at the bottom, and took 3 tries to find it - who knows.

Anyway, I would FIRST locate where the mounting plate or bracket needs to go - except for very light TV's it should bolt into studs - read the instructions. IF feasible, I would also avoid mounting it in a patch if rated for drywall mounting with your weight TV - you do not know how well that patch was done.

Then feed the cable to where the cord needs to come out to be the right place based on that mounting plate location, so you have the wire sticking out of the wall where you want it - THEN install the mounting plate. Then, finally, spackle or drywall compound to seal up the holes to prevent household air from getting into them - especially on outside walls where moisture in the wall can equal mold if you get cold at any time of the year in your area.

You did not say if the cable is in the wall now or not - otherwise you may have more feeding of coaxial cable or such to do.

When you say power socket - I hope you mean the low-voltage video cable to the TV - cable TV coax, HDMI, SVGI, etc. If you mean a 120V power cord - that should go to a proper wall outlet nearby and definitely should NOT be embedded in the wall. If no outlet within reasonable reach, then you can get an Electrical contractor to install one, or with a safely routed extension cord.

Hello LCD,

Thanks for your reply.

In my case, none of the holes at the bottom are on stud. They just made three holes for different things. One for a DirecTV cable, one has audio/video socket and other for internet connection(cable/dsl) socket.

Thanks for your suggestion. I will try to do something along the line you suggested.
