If the LCD screen is broken, you should consider selling your set for parts. The cost of a LCD replacement is not cost effective. Examine the screen to verify.
If the LCD screen is good you can check to see if the "image" is being "sent" to the screen.
1) Take a bright flashlight and place it against the screen with the set on.
2) If you see an image around the edge of the flashlight the problem is in the inverter/CCFT or the power to it.
3) If you do not see an image the problem is probably in the LCD Controller (TCON) or its connections.
