electrical problem
Im aware its a electrical problem. The fuses are still in good shape. I was kind thinking maybe the mother board is fried. Im wondering if maybe you know if there is anything I should look for? Or any ways to be sure it's the mother board. Wondering if this has happened to anybody and they fixed it inexpensively?
