Installing TV on media wall

[budest]

Hey all,

Family member needs a TV hung on this media wall and I am seeking some advice on how to do it. The wall behind is solid block with paster but what lies between the back of the media wall and the main wall?

Whilst I've hung a TV before, I just haven't done so on a media wall.

Thanks

You are fixing to wall ? Not media wall which is a description of finished project, just drill plug and fix bracket .
