Plasma Wall Mount Bracket I Have A Flat-screen TV, I Tried Wall-mounting It But It Fell Down, So Am I Doing It Wrong?

I have a flat-screen TV, I tried wall-mounting it but it fell down, so am I doing it wrong? - plasma wall mount bracket

I have this in the TV area, but nobody answered.

I bought a wall mount for it and everything and put it on the wall like the instructions said, but the TV is turned on, and broke down the retaining wall on the right wall. I know it can be done, because they can say that all flat panel TVs are wall-mounted. Luckily, the TV is still functioning.
This is the mounting bracket to the wall, I've used: http://www.amazon.com/Small-midsize-Plasma-Mount-Bracket/dp/B000YM9GU4
