LG part 6871QZH033A is what you most likely need.
There's a chance I might be wrong, of course.
But that would be my first guess.
There's a a guy having it REALLY cheap right now on eBay. I'd bit on it if I were you...starting price is like $10 and normal price is more like $70.
If it's not that then the second one is the YSUS board...he likely has that too.

You need to pull the power supply out and replace the damaged caps on the board. Look for swollen, pushed up tops and leakage around the base of the caps.
You need soldering and basic electronics skills. You also need to pull apart that big tv and pull the power supply board!
You can look on Ebay for pullout boards from people who have broken their screens. It can get you a working board for cheap sometimes!
Good luck and be careful!
