Ideas for temporary stand for a 65" Viera?

[Musashi]

The wall mount doesn't get here till late March, so I'm trying to see if there's a safe way to raise it up till then.

I have a cedar chest that's almost as wide as the TV is. I've considered leaning in against the wall. I also have a couple of heavy L-shaped metal plates and some wooden planks leftover from a shelf I built. I thought about wrapping the metal plats in towels and using the planks to reinforce the weight and bracing the front side of the TV with them. But I would like to see if there is a danger in doing this.

Any knowledge would be appreciated.
