wibbled:

Umm. Dunno. Seems to be plasterboard then a space then brick. Its an
outside wall of a Barratt house (built in the last 10 years).

It's probably block, not brick behind the PB.

BTW. Its not a heavy TV. Its a 15" LCD.

I hung some speakers up in a similar build flat years ago - they were
probably about as heavy as your TV.

If you can find a "dab" where the plasterboard is fixed to the wall, mount
the bracket on that and through into the blocks - that dab will be enough
to prevent the plasterboard crushing when you do the screws up.

Allow an extra inch on the fixings to clear the PB and the gap. Frame
fixings might also work quite well in this scenario but I've not tried.

If there isn't a convenient dab, I'd fall back to previous suggesstions
about cutting the PB out and inserting wood - or perhaps glueing the PB
back on solid PB adhesive which would achieve the same effect.

Cheers
