Black lines of pixels on an LG 55LM4700 LED TV?

I have an LG 55LM4700 55" 1080p 120Hz Cinema 3D Edge LED TV. My TV found itself the victim of an attack by a solid wood toy hurtling through the air (kids, sigh). Now, there is a vertical band of black pixels (5 inches across) as well as a horizontal band of black pixels (7 inches across) that intersect where the toy hit the TV.
