dot and dab is usually pretty uniform (ie if i find a dot then i can assume they'll be in line?)
Not in my experience. It all depends on who put it up. Often it is job given to a knuckle dragging labourer because it's messy and no skilled labour wants to do it. You may be able to find where the dots are by knocking on the plasterboard - if it's hollow sounding there will be a void behind it. In reality often the only real way to find out is to cross fingers and hope for the best.

Got a new TV arriving on Thursday (fitting Friday) which is completely flush mount (zero gap / full panel flat).
Two things need doing:
is going
The wall is dot and dab plasterboard to the internal outside wall (breeze block).
Job 1 seems pretty simple but wanted to check i'm not about to start a housefire:
I'm not going to plaster over the box hole as i may need it in future so i'm just going to cover with masking tape or something similar for now (it will be completely hidden behind the TV).
Second job, dot and dab is usually pretty uniform (ie if i find a dot then i can assume they'll be in line?). Does that mean if i cut a whole i should just be able to drop the cables vertically? They're only going about 40cm into a cabinet...
Edit: this is what i mean by zero gap btw...
