SOURCE: CRACK LCD TV SCREEN
I had one broken a few months ago. I got a couple quotes.. it was about $200 less then a brand new one. I'd just buy a new one.
For the new TV I'd pickup a screen protector for it. My son threw a toy at my TV the other day and I nearly had a heart attack from the flashbacks. Thank God I picked up one of these a few weeks earlier. It stopped it. LCD screens really break easily as you know. http://www.tv-armor.com

I have a 52" Samsung Series 5/ 530 Model LCD Flat Panel and I cracked the screen. The screen on the outside is not broke nor scratched but something hit it and now when I turn the tv on- it looks like i hit it with a hammer. How is this fixed? Can I do it myself?

Most LCD's just went down in price by around 2-400 dollars. I would suggest buying a new one. The cracked screen might mean that the liquid will ooze out and get worse and worse as it ages. However, it may only have a crack and not get any worse than it is now. If you can live with it and it doesn't get worse, you can view it that way for another 10 years and be fine.
The fact that the LCDs are cheaper now and you only have a 37 inch, you might consider getting a larger one that you have had your eye on for a long time. (Note: even though I am a firm believer in LCD's over Plasma, plasmas are a few hundered dollars cheaper and if you know your children are prone to breaking things... it might be the way to go.)
Replacing the screen is possible, but more costly than the new T.V.

If you still have back light, then the T-con is probably defective. If you don't have back light, then you either have a bad power board/inverter or a defective panel
