I am working with a white Macbook, made sometime in 2007, and it was recently dropped, we replaced the screen and it was working fine, the light came on and everything. We finally shut it, and re opened it, the backlight will not work, and it doesn't detect that it is closed, but anyways, we figured it was the inverter board, we replaced the inverter board, but the black cord did not fit with my logic board, so we hooked the old black cord onto the new one and still nothing, I really need help. I cannot find the original black inverter cord anywhere.
