We bought a TV a year ago with the intention of also mounting it on the wall. The wall bracket has been sitting in a corner of the spare room just staring at us, today I thought I'd tackle it.

And it wasn't so easy for me after all. First, there's a drywall (Probably? The house is from the early 1900s) then an empty space of 1-2CM, then there's wood 5-7CM.

I can't just screw through, then the drywall will probably "bend" in towards the wood. Let's say I carefully screw through, will the wall hold for screws that are 5-6CM into the wood, then "hang" in the drywall? The TV weighs about 22 kg by the way.

I'm so bad at this kind of thing, and I don't dare to just try either when it's the TV.

Regards, Fredrik
 
If your house is that old, it's probably not plaster you have in the wall but rather some kind of masonite board or similar.
How strange that there is a gap between probably the timber or wood to the boards.
If I were you, I would probably make a hole in the board where you want the wall mount. And then attach a stud to the timber which you can then screw the wall mount into.
That absolutely holds best because the TV must not fall down.

Do you have wallpaper or a painted wall? It's not so hard to cover the hole you make, especially since the TV covers it as well.
 
Did I understand you correctly that you have some sort of panel first, then a gap of about 2cm, and after that directly wood or is there another 5-7cm gap again?

A board, then a gap, and then 5-7CM wood. Then behind that, it looks like there's a gap again. I've only drilled one hole straight through for an antenna cable, so I can't see much else...
And it's painted on wallpaper...

As for making a hole and attaching a beam, that's far from my knowledge - worth mentioning is that this is a rental as well.
 
Okay! Then maybe tearing it down isn't so urgent. Unless you ask your landlord.
But I do think that if you use long, thick screws, it will hold really well.
There seems to be good wood to screw into, and I don't think the 1-2cm gap will matter since the mount is large and acts as a "washer" or support as well.

Does the board flex at all?

But I still think that if you use long, thick screws, it will hold like a rock anyway.

The screws that come with the booklet (4 pcs) are very thick. We put up a shelf on the same wall earlier, so I took some extra long screws, considering the gap and that it was plasterboard or something.. (So they would be set into wood then..)
And I tightened one a bit too much, then two plugs peeked out through the wallpaper, pretty annoying, unscrewed and tapped them back in, then tightened the screw a bit more gently.

I guess you might have to use the same method on the TV, tighten, but not too much.. In the worst case then we might break a TV, a TV stand, and a floor. Haha..
 
The main thing is that the screws are long enough to go a good bit into the wood.

Did you use plugs when you installed the shelf? You probably don't need plugs if you're attaching to the wood. Plugs are for the screw to grip and hold, which it already does in the wood.
The small gap between the plasterboard and the wood won't matter much; you can tighten it fairly hard.
Since the wall bracket will cover a large area of the wall, the force will be evenly distributed, and you can tighten it hard.

If you're unsure, you can screw in a screw and test it, pull downwards to see how it holds.
But it will surely hold well, you'll see.

How long is the screw?
You should have about 70mm for that so you'll go into the wood:)

The small gap between the drywall and the wood will not matter much; you can tighten it quite hard.

No, no plugs when I mounted the shelf.

Measured to be absolutely sure, should perhaps have done that from the start?

Drywall + gap 2-2.5cm. Then there is 3-4 cm of wood, hard to say exactly, there was no clear edge there, a lot of sawdust loosely behind the "wood part." The screws included with the bracket are 6cm and very thick, 4 of them.
 
Is it an interior wall? I thought so because you can determine how much wood there is.

It's probably fine to use the screws that come with it. As long as they go into the wood, it will hold. It would be different if you only had drywall..:)

Yes exactly, we drilled a hole straight through to the bedroom for the antenna cable.

Great, thank you so much for the response!
 
Make some sleeves from a piece of pipe or similar, long enough to go through the plasterboard into the wooden wall. Drill holes through the plasterboard so that the sleeves can bottom out against the wooden wall, then pass the wall mount screws through them. This way, the plasterboard can't be pushed in when you tighten.
The downside is that there will be slightly larger holes to repair if the TV needs to come down again sometime.
