It would be a tragedy to have a beautiful 60" Pioneer fall of the wall and get splattered on the floor.
Fully agreed. And it would be an even bigger tragedy to have that 120+ lb. Pioneer land on your two-year-old.
One horizontal 2X4 is not sufficient to support that kind of weight. I would double any weight-bearing vertical studs that were installed in the rough opening - or better yet, use 4X4s - and I would toenail them VERY thoroughly.
The bottom line is that you need to build a new area of wall with sufficient framing to support the display, that also looks good enough to keep your wife from screaming that you've wrecked the house. This is a fairly advanced task for most DIYers as it involves both rough carpentry and interior/exterior finish work. If you have any doubt whatsoever about your own skills, you need to hire a professional carpenter. And in most states, you will need a building permit before undertaking any structural work like this.
