Sharp aquos 70 inch is dark at the bottom

[Groucho1]

My Sharp aquos lc70le733u has a problem. Lightning struck near my house. my cable box is dead and my tv would show anything from the hdmi inputs. I ordered a new mainboard and installed it. it had a 1-1 flasing power light. i reset it with the vol up channel down method. now i have menus but the screen is dark at the bottom and the input still don't work. it says i have the latest firmware via wifi.

Wrong Forum. But it sounds as though the lighting damaged more than just the mainboard.
