Mounting TV

[rsbhj]

Hi

I am planning to mount TV on the wall in kitchen/diner.

The wall is outside brick, and I plan to raggle the wall and fit in trunkin big enough to feed 1 x power cable and 1 x hdmi 1 x cat6 down it.

Top and bottom will be a single pattress box for the cable entry/exit.

My question is where do I have the cables coming out behind the TV? I've attached a photo of the rear of the TV and marked red X where I think would be best area behind the TV.

Thoughts?

I previously used D line trunking surface run which was fine but since the walls are getting plastered thought best to raggle in some trunkin.

i would have the cables exit the wall in the area of the left hand x in the pic and then route the cables over the top of the centre to the connections on the other side. if you use stick on cable tie bases you can keep the route across the top of the centre bulge tidy and the cables wont sag down and show

Thanks @Sureitsoff? great advice, never thought of that way to take the cables, will bring the cables out on the left side.

Other option I guess is in the middle, above the bit that sticks out towards top of TV blue X. Above option tho prob gives more room for error or play.

I had originally though to bring them out at the bottom of the TV in the middle as thats how it was done last time with the surface D line trunkin but wasnt until I was look at the back of the TV that space where the X is seemed the most logical space for room.

Is there anything smaller than a single socket pattress box that coule be used?

Above and centre line of the bracket. Tye TV should be on a bracket with a bit of tilt anyway, so there'll be more space above the bracket compared to anywhere else.

Don't bother with socket face plates. Bury a backbox as normal, but use a brush plate to finish off. Leave enough speared cable to reach a foot or so past your present TVs socket positions. This spare cable hides in the wall or under the floor. Doing it this way means the signal cables are always the right length since you just pull out what's needed.

Thanks @Lucid

My phone plan was to chase the wall and install trunkin and plaster over however am I mad to think I might be better to drill a larger hole through the wall take the cables externally down the outside wall and back in?

I could have conduit or outdoor cable protecter guard over what would be tv power lead and hdmi cable.

Where its an outside wall then there should be a cavity between the inner and outer skins of block/brick-work.Depending on the age of the property there may be insulation in some of that space, but it may still be possible to pass cables down without going outside.

It's worth mentioning that running power cables close to or through insulation can create an electric blanket effect with small cross sectional area conductors, so it's a good idea to overrate to something thicker with larger CSA conductors. An LCD LED TV won't draw a lot of power - 200W at most unless gigantic - so the cable size doesn't need to be massively overspec'd.

Running outside is a possibility, and certainly the conduit will help by offering some protection

I think the walls have been filled with cavity wall insulation, its a 1960s property.

The power cable would be the lead from the power pack that is through the wall. It might be easier just to chase the wall and put in a new power socket behind the TV, then trunkin in for the HDMI, just need the HDMI for the SKY Q mini

Don’t forget an aerial cable.

no need for aerial, all through sky q mini, or netflixs, amazon, Disney etc, no need for freeview

you can get a box smaller than a single, it is known as an architrave box and is about half the width of a normal box. but i dont think i have seen a brush plate to fit, unless you make your own

One day you will realise sky is an expensive ripoff, then you will need an aerial.

If it comes to that then its easy enough to run the aerial cable trough the wall

Thanks @Sureitsoff? they smaller ones look idea

 

[rsbhj]

wonder if this knock out hole will fit an hdmi through it though? Anyone used it?

The gap i need to cover is 35cm from bottom of TV to top of table wonder if I ma better just using D line again!

 

[rsbhj]

Is there something else I can use rather that this type of pattress box? I just dont think those circle cut outs will fit an hdmi end through easily?

Trunking in the wall is fine, but just dont want the cables to just hang out the wall.

I thought about a plastic surface box an cut the full bottom section from it .
