1) buy some metal studs or make them by cutting down threaded rod and adding nuts and washers. 6mm or 8mm diameter rod will be fine for hanging a plasma screen as long as the wall is sound and you fix with 6 points.
2) buy a suitable drill bit approx 4mm bigger than the diameter of the studs being used. i.e. 6mm stud = 10mm drill bit
3) offer up bracket and mark the fixing points (normal caveats apply about ensuring you watch out for pipes and cables, and that you have a sound wall to fix to.
4) drill holes to the depth of the stud's length. Know the depth of the wall you are fixing to. Don't drill deeper than the thickness of the brick or block. If necessary cut down the length of the studs to suit. Allow for 10-15mm of the stud to be proud of the hole - this is what you'll fix to.
5) clean debris from holes - use vac attachment
6) check alignment of holes with bracket
7) set up your resin anchor in a mastic gun and ensure you have the studs to hand. Get a cloth for cleaning excess resin. You can use masking tape to protect the wall finish and also use it to make a support sling if you find the studs drooping after being inserted
8.) read the setting time in the instructions for your resin compound. Take note of the room temperature
9) working one hole at a time - part
fill a hole with some resin, then take a stud and insert it with a clockwise screwing motion. Set the depth so that enough stud is left exposed. Clean off any excess being careful not to get it on the thread of the rod. Dried resin will be difficult to remove.
10) Clean your hands before moving on to the next hole, and repeat the process
Notes - avoid the temptation to fiddle with the studs as they are setting.
