Have 42 inch LG flat screen...for about 3 years...

Main Control Board bad !

well if you could please give out the model nuumber thank you

Buffer boards or Y-SUS main needs to be replaced. What do you mean by motherboard? The power supply board or the Logic or X main.... They YBU/YBL and the YSUS work in unison. Y-Buffer upper controls top half, Y Buffer lower control bottom have YSUS controls both of those. There is also D, G, E F boards that can split screan. But they to are controlled with the Y-SUS Main. Hope this helps...

Bad x-address board.
