Drilled too big hole in brick - how best to recover it

    Heya guys,

    I have a chimney breast, was going to hand a TV on it, however I didn't know previous decorators plastered over what seems like pebbledash (when drilling in the first 1/2 inch has random pebbles/stones with maybe sandstone or something).
    Anyway, the first hole went ok to a point, and then went a bit wrong towards the end, meaning my 10mm hole is now an 11mm hole and the plug rotates.

    I am wanting to recover the first hole, and don't just want to use "Polly filla" or shine some matchsticks in, as I'll be hanging my TV off of it.

    I have tried searching online and not been able to find much on repairing holes for reuse, but have seen 2 or 3 methods I think seem good:
    1) clean the hole and put in some sort of epoxy, let it dry, drill pilot hole with wood bit, screw into epoxy.. basically making epoxy my anchor - and it should do well by filling the hole really well.
    I like this, might be a tad expensive compared to normal plugs - but it would allow me to use the large hole and ensure the screw is in the right place.

    2) use some mortar or repair cement or something similar.. I think the repair cement will be too hard for my current tools, while the mortar will probably be too crumbly?

    3) some sort of resin. Same idea, but the screw gets set in place.. really don't like this idea, the screw needs to be put in place prior to the resin drying, and then can't really be removed after.

    The holes are just over 3 inches deep, and I'm definitely into the brickwork.

    Any help would be appreciated (brands/products/solutions).

    Thanks

    Frame fixer or expanding bolt? Or find a new location for the hole.

    10mm fixings will be capable of supporting a van full of TVs

    10mm is way over the top to mount even the largest tv.

    Use a vacuum cleaner to suck any dust out and buy some gripfill. Fill the hole and insert the rawl plug
    Allow it to dry and carry on

    Quite. I think most people massively overestimate what is required to hold the average modern LCD TV up. A £10 bracket from amazon and half a dozen (if you're feeling generous) plain old screws and rawlplugs is all you need.
